Varian Vista-MPX ICP-OES

You asked us for an ICP that was moreproductive and more affordable. We listened.Today, Varian is proud to introduce the Vista-MPX™, delivering the productivity of simultaneous elemental analysis at anaffordable price.

The secret to this performance is theinnovative MPX megapixel detector, the firstto provide over 1.1 million pixels in a CCDarray detector design. The Vista-MPX givesthe benefits of full wavelength coverage and simultaneous measurement. Full wavelength coverage means spectralinterferences can be easily avoided.Simultaneous operation means better resultsprecision, improved background correctionand higher productivity. Quite simply, Vista-MPX gives you better answers, faster.

The Vista-MPX is ideal for environmental,chemical and industrial laboratories, offeringa host of benefits including:

• The productivity of simultaneous measurement of all elements from parts-per-billion to percent levels with the unique megapixel CCD array detector.

• Simple 'one step' analysis that saves you time and argon costs. The optimized plasma viewing systems of the Vista-MPX means that, unlike dual view systems, you don't have to analyze the sample twice.

• Rapid instrument set-up, operator training and method development from our powerful ICP-Expert™ software which is versatile and easy to learn.

• Fast optimization and hands-free operation, from full PC control of all instrument parameters.

• The confidence to analyze any sample typewith Varian's robust free running 40 MHz RF generator.

• The highest reliability from no moving parts optics and RF generator designs.

At Varian, our research challenge was to provide the productivityand performance benefits of a simultaneous ICP-OES at the priceof a sequential system. The solution was to create a CCD arraydetector with the ability to capture the entire wavelength spectrumin one reading without scanning. The MPX is the world's first ICPdetector to provide over 1.1 million pixels in a large area, CCDarray design

“Simultaneous ICP-OES”

With the Vista-MPX, you can experience all thebenefits of simultaneous ICP-OES. Because theVista-MPX captures the entire spectral image in one reading, you save time and argon costs.Whether you have tens or hundreds of samplesto analyze each day, Vista-MPX will save youmoney. Simultaneous ICP means simultaneousbackground correction and internalstandardization–resulting in more accurate and precise results with excellent long termstability. The unique MPX CCD array detector is cooled to -30˚C for the ultimate in low noise performance and best possibledetection limits. For the best valuesimultaneous ICP-OES–choose Vista-MPX.

The excellent long termstability of the Vista–MPXis shown over 20 hours of continuous aspirationwithout internalstandardization.Simultaneous ICP–OES with no moving opticalparts yields superiorstability without driftcorrection lamps.

To ensure data integrity and a wide dynamic range the Vista-MPX CCD features theClocked Recombination System(CRS) for anti-bloomingprotection.

Excellent long-term stability froman optimized optical design. Thegrating and prism are fixed andthe echelle polychromator is fullythermostatted, providing a reliable,no-moving-parts design that doesnot require correction lamps.

Spectral interferences are easilyavoided with the full wavelengthcoverage of the Vista-MPX.Choose any wavelength from175-785 nm. Unlike othersimultaneous ICP-OES designs,Vista-MPX covers all theimportant wavelengths in the visible region withoutcompromise.

The productivity of simultaneousICP-OES–all wavelengths arecaptured in one reading withouttime consuming scanning.

Varian Vista-MPX ICP-OES

Difficult sample measurementsmade easyNo matter what the sample, the Vista-MPXprovides excellent long-term stability. Toachieve this, Varian created the Direct SerialCoupling (DISC) system that improves thetransfer efficiency of RF energy into theplasma by eliminating inefficient secondarymatching networks. As a result, the Vista-MPXRF system produces a robust and stableplasma, suitable for the direct analysis ofsamples ranging from organic solvents toindustrial wastes and concentrated brines.Unlike crystal locked designs, Vista's freerunning RF generator respondsinstantaneously to changes in the plasmaimpedance for superior stability.

“Robust and Reliable RF Systems”Varian’s ICP systems have always provided stable and accurateanalytical results, even for the most challenging samples. Utilizingour established high performance RF generator, Vista-MPXcontinues this tradition of excellence, offering:

• Superior plasma performance from over 75% RF coupling efficiency. Directly analyze organic solvents and samples containing high levels of dissolved salts.

• Excellent long term stability through the elimination of inefficient secondary matching networks and reduced waste heat.

• Higher uptime, better reliability and lower service costs as there are no moving parts.

• The flexibility to easily analyze your full range of sample types. Varian's compact 40 MHz free running design responds quickly to any changes in plasma sample loading and volatility.

• Reliability and servicability are maximized by the elimination of water cooling.

Linear Dynamic Range from Parts PerBillion To Percent LevelsThe unique Vista-MPX CCD detector providesfull wavelength coverage from 175—785 nm.Our unique MultiCal feature then automaticallyassigns each result to the appropriatewavelength for that result. MultiCal extendsthe linear range of ICP-OES analysis fromparts-per-billion to percentage levels. Unlikedual view systems, Vista-MPX provides thislinear dynamic range without having to analyzethe sample twice. Vista-MPX provides one-stepanalysis from a single plasma view.

Automatic Results ConfirmationOne of the greatest challenges in thelaboratory is to prove that you have accurateresults for unknown samples. Vista's MultiCalcan help by providing automatic on-lineresults confirmation throughout the analysis.Use MultiCal to simply monitor your results at two or more wavelengths for each elementand you have automatic results validation.MultiCal offers an extra level of data qualitycontrol–giving you confidence in the accuracyof your results and confirmation of freedomfrom interferences. If you are not usingMultiCal confirmation today–how can you be sure of the accuracy of your data?

Vertical or Horizontal Plasma?Vista-MPX offers either optimized axiallyviewed or radially viewed plasma systems. The horizontal, axially viewed plasma is idealfor environmental applications that requireexcellent sensitivity and MultiCal provides thedynamic range needed from one plasma view.Varian's axially viewed plasma is suitable forthe routine analysis of samples with dissolvedsolids contents up to 5%.

If long term analysis of the most difficultsample types is required, the Vista-MPX radiallyviewed plasma offers the benefits of robustoperation with minimal maintenance. Theradially viewed plasma is vertically oriented,providing immediate venting of exhaustvapors for reduced injector tube blockage.Vertically orientated, radially viewed plasmasystems have become the accepted standardin many industries including chemicalsmanufacture, salt production, wear metalsanalysis, petrochemical production andprecious metals refining. Dual view plasmasystems, which feature horizontal torches,cannot match the rugged, high dissolved saltperformance of the Vista-MPX radial.

The advantages of MultiCal–results for Ca are automaticallyassigned either to the Ca 315.887 nm wavelength which iscalibrated to 30 mg/L or to the Ca 370.602 wavelengthwhich is calibrated to 600 mg/L. With MultiCal the InitialCalibration Verification standard is accurately recovered at 47.7 mg/L (%R = 106%) from the appropriate wavelength.

FACT’s power can also be used after the analysis has beencompleted. If any of the results appear inaccurate, FACTmodelling can be conducted after the analysis and appliedto the data to solve spectral interference problems andprovide greater accuracy. With FACT, your data is neverwasted.

For even greater productivity, our built-inFast Automated Curve-fitting Technique(FACT) achieves on-line spectraldeconvolution with no time penalties. Foryour most complex spectral interferenceproblems, simply aspirate a typical samplematrix and use the FACT wizard to solvespectral interferences. Traditional spectraldeconvolution techniques require spectralscanning methods that can triple orquadruple the analysis time. FACT'sproductivity means you can analyze moresamples per day and further reduce argonconsumption.
