intoxilyzer 8000 - ohio state bar...
TRANSCRIPT
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.
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.
