Colorado is preparing to upgrade its current evidential breath alcohol test instruments. The state has been using the Intoxilyzer® 5000, but will soon be replacing it with the latest infrared instrument manufactured by CMI Inc., the Intoxilyzer® 9000. The Colorado Department of Public Health and Environment (CDPHE) has already spent about $1.7 million on the new machines (not including the costs of training thousands of law enforcement officers.)
The Intoxilyzer® 9000 is a four filter infrared instrument measuring alcohol in the 9 micron range. The new software is based on Windows, unlike previous instruments that used other programming language.
The state of Georgia is making the same change and recent laboratory testing conducted by the Georgia Bureau of Investigation concluded that the machine was the most accurate among the available models on the market. A summary report appears here.
The new device incorporates an “exception message” function. Retesting may be required under a variety of circumstances, with a new 20-minute “deprivation period” required under certain circumstances. In addition, the operator is required to enter “comments” for other exception messages.
Key differences between the previous model and the I-9000 are as follows:
|Number of Filters||5 filters||4 filters|
|Filter Range||3.5 microns||9 microns|
|Infrared Source||Halogen lamp||Pulsed Light Emitting Diode (LED)|
|Logs||Paper: created, printed & managed||No printed paper logs|
|Solution changes||Changed every 28 days||“as needed”|
|Weekly Calibration checks||Manual||Automatic|
|Operator Certification||Paper driven via instructors||Access card driven|
|Data Management||Only current test reprintable||Previous tests reprintable directly from instrument|
|Report Signatures||Manual||Electronic signature pad|
|EBAT Test Printout||Only prints numerical results||Prints breath and alcohol histogram curve|
As with any other instrument, the results of the device in any particular case are only as good as the training and methods used by the operator and the training and certification process has taken longer than initially expected.
