5. X-ray OpticsThe Orbis product line can use a variety of collimating and total reflectance X-ray optics. In the standard Orbis
Micro-XRF Spectrometer, small spot mono-capillary optics are used to generate a semi-parallel beam. As an
option, large spot collimators can be added to the turret to expand the capability of the instrument. Large
spot collimators are useful in creating a homogeneous beam over a larger area for analysis of larger sample
features and sample volumes (e.g. powders and granulates) or fast mapping to cover large areas where a
small X-ray beam is too fine. In the Orbis PC Micro-XRF Spectrometer, an ultra-high intensity poly-capillary optic
is used to generate a high sensitivity convergent micro spot X-ray beam. Large spot collimators can also be
added in the turret as an option with the poly-capillary.
6. Fast XYZ StageThe Orbis product series uses the latest in piezo-electric stages to drive the
X, Y axes for fast sample movements while using a stepper motor on the Z axis
to handle more massive samples.

Orbis Micro-XRF Applications
Measuring Metal Distribution in CeramicCatalyst SupportsThe Orbis PC mapped the Pd distribution in an
extruded Alumina pellet with a reported Pd loading
of 5 wt%. The Pd(L) line was used to limit the
penetration depth of the analysis on the cross-
sectioned surface of the pellet. Standard thermal
image scaling shows the Pd to be primarily
distributed in a thick shell at the surface of the pellet.
Specialized image scaling available in EDAX software
reveals a lower level concentration of Pd in the core
of the pellet which is obscured in the standard
thermal scaling by the high Pd concentrations in the
pellet’s outer shell. With the optional 2 mm collimator,
average metal content can also be determined by
measuring the homogenized ceramic pellets.
Industrial
Measuring Pb on Printed Circuit Boards forRoHS ComplianceThe screening of samples for restricted or banned
materials and chemicals is becoming increasingly
important. European law, which has quickly spread
in various forms globally, restricts the use of Hg, Pb,
Cd, hexavalent Cr, and Br, in certain fire
retardants in consumer electronics and other
electrical appliances. Micro-XRF can be used to
determine Hg, Pb, and Cd levels and identify
components with significant levels of Cr and Br
requiring further definitive testing. In this case, a
printed circuit board has been mapped, showing the
use of Pb-based solder on the board.

Phase Identification Through Mapping and Spectrum Matching
IntroductionWith the addition of Spectrum Matching to the EDAX TEAM™ software package, another powerful and time saving tool isjust a few clicks away. Spectrum Matching is an automatic function that allows the user to search through a custom built spectrumlibrary to find similar spectra. This greatly simplifies identification of unknowns by comparing them to a group of potentialcandidates and reduces the complexity of finding discrepancies and similarities between spectra.
The matching of the active spectrum to those found in the libraryfile is based on a chi squared goodness of fit test, comparingeither concentrations or spectra directly. The match sensitivity isadjustable, giving the user full control over the match results,ranging from completely identical to roughly in the sameballpark. The potential matching spectra are overlaid on theoriginal spectrum with the match percentage giving a measure ofhow similar or dissimilar the spectra are along with a visualrepresentation of the differences. Figure 1 shows an examplespectrum with two overlaid spectra with a match value of 81.53%for SbS and 62.64% for CaSO4. A visualinspection quickly tells us that thediscrepancies between the sample and the bestmatching spectrum are to be found in the Si,Ti, Ba and Zr content.
Building a spectrum match library in theTEAM™ software is made easy through theincluded spectrum search utility. The user isable to search the full database of spectrastored on the system either through manual
selection of specific project nodes or byadding filters to identify spectra with thedesired characteristics. The filters includeacquisition date, presence of given elements(with range in atomic %, weight % or netintensity), sample name and kV used. Oncethe spectra are selected, they are saved to aSpectrum Matching Library file, which can beshared amongst users and systems. It is evenpossible to add all data in the system databaseto a Spectrum Matching Library file in orderto finally answer the nagging question of“Hmm, where did I see this before?”
Combining phase mapping and Spectrum Matching highlightsthe benefits gained from both techniques. In the current example,we have built a spectrum library based on 15 different mineralstandards and applied the library to a high quality 512x400 pixelmap of an automotive composite sample. During the one hourdata acquisition, the phase mapping routine automaticallyseparated and color coded the different phases of the sample asshown in Figure 2.
Figure 1. EDS spectrum with two matching spectra overlaid.
Figure 2. SEM Image (left) and phase map (right) of the composite sample.
Technical Note - EDS
Upon identification of the phases, the TEAM™ softwareautomatically generates a phase spectrum from the pixels in eachindividual phase. These phase spectra can easily be pulled up inthe software and compared to a match library. Figure 3 illustratesthe result of extracting the blue phase spectrum from the phasemap and matching it to the minerals library, resulting in an85.33% fit to a barite standard. Figure 3 also shows the Ba atomic% map alongside the phase map, confirming the presence of Bain the blue phase.
By matching the other phase spectra, we can rapidly identify thered phase as almandine garnet, steel blue as magnetite, turquoiseas strontium sulfate, yellow as a mix of barite and titaniumdioxide, and violet as lead sulfate, while fuchsia is assigned tothe carbon resin.
ConclusionWhile this example shows the matching routine applied to a mineral sample, Spectrum Match is a versatile tool that finds amultitude of applications. These include failure analysis and quality control where defects can be compared to a library ofpotential contaminants, process control where changes in distribution and composition can quickly be identified with thecombination of phase mapping and spectrum matching, or reverse engineering where material constituents can be matchedagainst a library of standard components found in the material. Whichever the application, users will now be able to find theirmatch with the click of a button.

GSR Analysis Using SEM/EDS
The discharging of a firearm initially produces a plume of airborne particulate from the burning primer mix that deposits on any available surface. It then solidifies into fine particles and settles onto the hands, clothing, and surfaces in the immediate proximity of the discharged weapon. The particulate of interest is composed of Pb, Ba, and Sb, in varying proportions, and other components of the primer compound The combusted material escapes the weapon through the openings as vapors and solidifies as particulate that vary in size from submicron to over 100 µm. GSR analysis determines the presence of these materials on the skin and clothing of the subjects as well as surfaces such as vehicle interiors and exteriors where the particulate may be deposited.

Fiber analysis by thermal desorption/pyrolysis DART® Introduction Analyzing fiber samples has always been difficult by DART®. The problem has been that there is no easy way to hold the fiber in the gas stream without losing it into the vacuum system. A fiber can be secured in the DART gas stream with forceps or other means, but if the DART gas is too hot, the fiber can break off and be lost into the mass spectrometer vacuum system through the atmospheric pressure interface.
A thermal desorption/pyrolysis stage (The Biochromato, Inc. “ionRocket™”) designed for use with DART produces highly reproducible thermal desorption profiles that show outgassing, additives, and high-quality pyrolysis DART mass spectra for materials. Because fiber samples placed in the disposable copper sample “pots” are not positioned directly in the DART gas stream, a single fiber can be analyzed without risk of loss into the vacuum system.
Experimental Mass spectra were acquired by using a JEOL AccuTOFTM-DART® 4G mass spectrometer (Figure 1) equipped with a Biochromato, Inc. ionRocket thermal desorption and pyrolysis system (http:// biochromato.com/ionrocket/).

A single fiber or a small clump of fibers was placed into a disposable copper sample stage (or “pot”) for the ionRocket (Figure 2).
Figure 2. A copper pot used as a sample holder for the ionRocket
The copper sample stage was placed onto the ionRocket heater (Figure 3) and moved into position between the exit of the DART ion source and the sampling orifice of the AccuTOF-DART 4G mass spectrometer. A glass tee positioned above the sample (Figure 4) guides the thermal desorption and pyrolysis products into the DART gas stream.

Figure 4. A sample mounted on the heater block, positioned below a glass tee.
The temperature ramp was programmed from ambient temperature to 600°C at a rate of 100°C min-1. Mass spectra were acquired at a resolving power of 10,0000 in positive-ion mode at a spectral acquisition rate of 1 spectrum per second for the m/z range 50-1000.
Results Carpet fiber A small tuft of fibers from the carpet in the JEOL booth at PittCon 2016 was placed onto a copper sample holder for the ionRocket and analyzed by the AccuTOF-DART. The thermal desorption profiles of selected components are shown in Figure 5. Oleamide, a common stabilizer shows a maximum abundance at temperatures below 200°C. The stabilizer 2,5-di-t-butylhydroquinone maximizes at temperatures just above 200°C, and high-m/z pyrolysis products from the polyolefin fiber maximize at temperatures above 400°C.

Fiber from a badge holder lanyard A single fiber from the badge holder lanyard from PittCon 2016 was placed onto a copper sample holder for the ionRocket and analyzed by the AccuTOF-DART (Figure 6). At temperatures below 300°C, we detect additives such as dibutyl phthalate plasticizer. At higher temperatures, we detect pyrolysis fragments from the polyethylene terephthalate (PETE) polymer.
Figure 6. Thermal desorption profiles and mass spectra for components in a badge holder lanyard.
Conclusion Thermal desorption/pyrolysis with the ionRocket offers a convenient solution for the analysis of single fibers with the AccuTOF-DART. Accurate-mass and isotopic data measured by the AccuTOF-DART system allows us to detect additives and identify the base polymer. Because the fiber is not held directly in the DART gas stream, there is no risk of losing the fiber into the mass spectrometer vacuum system if the fiber decomposes upon heating.

Applied Polarized Light Microscopy (1201)/Forensic Microscopy (1204) July 18–22 and September 12–16, 2016 Students will acquire the basic knowledge and practical skills to apply polarized light methods in their areas of interest and will appreciate the potential contribution of more advanced methods and techniques. The materials examined empha‐size particle analysis, including fibers, paint, glass, hair, explosives, soil, drugs, etc.
Microcrystal Tests for Illicit Drugs and Diverted Pharmaceuticals (1725)* New course August 15–19, 2016 This course teaches basic and advanced techniques for the identification of illicit drugs and diverted pharmaceuticals. An emphasis on polarized light microscopy and optical crystallography methods will allow students to recognize and identify specific microcrystals formed in the presence of targeted drugs. Major drug categories are covered, including narcotics, depressants, hallucinogens and stimulants. Street samples and pharmaceuticals will also be available for microscopical analyses.
Animal Hair Identification (1208) New course August 30–September 1, 2016 This course will introduce mammalian taxonomy, the importance and establishment of reference collections and hair atlases. Lectures explain the morphological and anatomical features of hairs that may be used for their identification. Demonstrations show how hairs can be sequentially prepared so that all of these characteristics can best be observed, if necessary, on a single hair. Students will prepare microscope slides, scale casts and cross‐sections and then microscopically examine them.
Comparative Microscopy of Soil (1710)* October 3–7, 2016 Students study the composition and origin of soils and approaches to scientific soil comparison through lectures, demonstrations and laboratory exercises. Small soil samples are literally taken apart and separated into clay, silt and sand size fractions, light and heavy minerals, and concentrates of pollen, spores, diatoms and phytoliths. At each stage appropriate methods of analysis are explained and demonstrated before students conduct their own laboratory exercises.
Introduction to Basic Human Body Tissues (1557) New course November 15–17, 2016 Taught by Lynne D. Herold, Ph.D., this three‐day course will introduce the seven basic human body tissues: nerve, muscle, bone, epithelium, connective tissue, blood, and cartilage. Instruction will include lectures, group viewing of prepared and unprepared body tissues, and individual hands‐on laboratory exercises for simple preparations and observations of body tissue at macroscopical and microscopical levels. This course bridges the gap between traditional trace evidence examinations and DNA analysis.
*The prerequisite for this course is McCrone’s Applied Polarized Light Microscopy (1201)/Forensic Microscopy (1204) course or equivalent.

A Modern Compendium of Microcrystal Tests for Illicit Drugs and Diverted
Pharmaceuticals
M cCrone Research Institute announces its new online publication,
A Modern Compendium of Microcrystal Tests for Illicit Drugs and Diverted Pharmaceuticals, which fulfills a critical need for reliable analytical methods and assists forensic scientists and other researchers in their work. This compendium contains 19 drugs for which microcrystal tests using various reagents have been previously developed. It describes in detail the microcrystals formed from each test and includes photomicrographs, morphology illustrations, optical properties, notes and infrared (IR) spectra of the microcrystals. Microcrystal tests, using polarized light microscopy (PLM), can identify most illicit drugs specifically and quickly, and they are inexpensive compared to other methods. In addition, proper use of the light microscope and microcrystal tests can check and confirm the results obtained by alternative methods. The photomicrograph (above) shows a microcrystal test for pseudoephedrine with dilituric acid. Learn more and download the Modern Compendium of Microcrystal Tests at www.mcri.org.
