Intoxilyzer 8000

Intoxilyzer 8000 (OH-5)

What You

Need to Know

Theory of Operation:

1. The Intoxilyzer 8000 uses the method of INFRARED ABSORPTION to

analyze the breath sample.

2. The IR light source is a PULSED INFRARED light.

3. The wavelength frequency is 3.4 and 9.4 MICRONS for alcohol and

other interfering substances.

4. The decrease in intensity of the JR light due to absorption by alcohol in

the breath sample is proportional to the amount of alcohol in the breath.

5. The sample chamber holds 29.4 cc=s of deep lung air for the analysis.

Difference from previous machines:

Previous machines, BAC DataMaster, BAC DataMaster CDM, BAC

DataMaster DMT, Intoxilyzer 5000, Intoxilyzer 5000 EN, all used infrared

absorption as the analytical method.

The sample chamber in previous machines contained

DataMaster 50 cc. in the BAC DataMaster and 38 cc. in the BAC

DataMaster CDM 38cc

Intoxilyzer 5000 EN 84 cc.

Intoxilyzer 8000 29.4cc

Of more significance is the light path length in the sample chamber.

Machine Sample chamber size light path length

Intoxilyzer 5000 EN 81.4 cc 11.4 inches

Intoxilyzer 8000 OH-5 29.4 cc not specified

DataMaster 50 cc 43.3 inches

DataMaster CDM 38 cc 33 inches

The length of the light path is significant in that the farther the energy

travels through the breath sample, the more time the energy has to react to

the sample. This translates into a greater sensitivity of the machines with the

longer light paths. Source DataMaster Supervisor Guide p. 2.

Both the DataMaster and the Intoxilyzer 5000 EN utilized a spinning

wheel containing multiple filters to test specific frequencies for infrared light

absorption. The Intoxilyzer 8000 does not use a wheel, but rather pulses the

light. The elimination of the wheel eliminates moving parts, hypothetically

decreasing the possibility of maintenance, but also requires a slower

processor, which results in a reduced number of samples of the breath,

which reduces the sensitivity of the machine to errors.

In particular, the short light path and slow operating speed, due to the

pulsed infrared lamp, makes the Intoxilyzer less able to reliably detect

mouth alcohol and flag invalid samples compared to existing older

technology.

The processor in the DataMaster series of machines runs at 525

megahertz which results in 125 samples per sec of the breath sample. The

Intoxilyzer 8000 only takes 4 samples per second of the breath sample. The

result is that the Intoxilyzer is not able to detect the negative slope with the

same accuracy or reliability as other machines on the market, including the

older Intoxilyzer 5000 EN and the DataMaster family of machines.

The result is that the Intoxilyzer 8000 is less able to detect mouth

alcohol in subjects. This has been verified by testing conducted by the

Alaska Department of Highway Safety, which after the testing, has not

approved the machine for use in Alaska. Similar testing in Minnesota has

caused that state to not approve the Intoxilyzer 8000 for use in Minnesota.

The Intoxilyzer does leap ahead in that the test sequence provides for

two breath sample and two external calibration checks. This is the “dual

testing” that has been recommended for forensic testing since at least the

1970s and utilized in many other states. This same capability has been

available in the existing breath testing machines, but has never been utilized

by the Department of Health, although it’s implementation would not have

increased the cost of breath testing and could have been enabled by the

pushing of a few buttons without even having to take the machines out of

service.

National standards for forensic testing utilizing other testing methods

used to test bodily fluids and substances, such as the gas chromatograph,

have been required to utilize multiple point calibration checks and quality

control samples to be run with at least two samples of the unknown sample

for years. Many states has used dual testing for years as a basic check of the

accuracy of their breath tests.

Another feature of the Intoxilyzer 8000 is that it will automatically

report the results of all breath tests and calibration checks to a database

maintained by the Ohio Department of Health, which is available on line to

the public. http://publicapps.odh.ohio.gov/BreathInstrument/ Anyone can

access the database and review information on all the machines and tests.

A similar online data collection has been utilized by several states for

several years, with the additional benefit of being able to compare the data

by the downloading of the data in spreadsheet format. This feature is not

available with the existing Ohio format. The online data collection feature

was also available on previous machines approved in Ohio, but ordered

either removed or deactivated. This is somewhat paradoxical in that the

whole concept of the DataMaster family of machines was the ability to

collect test data and report it to a central data base, as is now being done

with the Intoxilyzer 8000 (OH-5), but not the (OH-2) version utilized by the

Watercraft Division.

The Intoxilyzer 8000 also has some bells and whistles not available on

the older machines. It has a scanner that can read the magnetic strip on

driver’s licenses and automatically enter the data on various forms generated

by the machine. The machine can also read the operator’s access card,

which is used to automatically enter the operator’s information. The number

of forms that the Intoxilyzer prints out is dependent on what the operator

requests. Several standard OVI forms, including a BMV 2255 form can be

generated.

http://publicapps.odh.ohio.gov/BreathInstrument/

The test record printout also contains a significant amount of

information not available on the older machines approved by the Department

of Health. The specific information will be presented during the seminar

presentation.

A wealth of information on the Intoxilyzer 8000 (OH-5) and the tests

are available on line. In perusing test results a number of “impossible” test

results have been noted, together with a significant number of incomplete

tests with “ambient fail” results. Some of these tests will be displayed

during the presentation.

This test result is a classic example of mouth alcohol. The first test is well over the legal

limit and the second test is just under the legal limit. A single test would only have reported

the higher test result. Note that the machine did not report an invalid sample error.

This is a good example why single tests should not be admitted in OVI cases.
