The BreathScan® Alcohol
Detector
The BreathScan®
Breath Alcohol Test is considered by many to be the best example of these devices.
BreathScan® is a portable, disposable alcohol detector with an extremely
low unit cost that makes it suitable for general use in the workplace or other
remote locations. Various independent agencies have conducted validation
studies that examined the BreathScan® instrument's accuracy and suitability
as a preliminary screening device when used to determine probable cause for
more extensive testing. The following is a survey of their
findings.
U.S. Department of Transportation, National Highway Traffic
Safety Administration
The
NHTSA looked at the use of BreathScan® specifically as an aid to police
officers in making an objective evaluation in drunk driving cases. While not
intended as an evidenciary test, the NHTSA found BreathScan® suitable as a
first line of BAC quantification. The NHTSA determined that the BreathScan®
breath alcohol test was able to accurately distinguish between alcohol levels
below and above .10% BAC (or .08% BAC for BreathScan® units calibrated at
the lower BAC level). Several tests at different room temperatures were
performed in accordance with established methodology. Since evaluation
specifications for preliminary test devices do not exist, the NHTSA used the
guidelines "Specifications for Evidential Breath Testers", specifically the
precision and accuracy tests, the blank reading test, the breath sampling test,
the ambient temperature test and mobile test from existing NHTSA guidelines.
Using standard aqueous alcohol solutions contained in 34-degree thermostats,
researchers duplicated breath alcohol concentrations in controlled
conditions. This breath sampling detector was designed to yield maximum sampling
consistency and efficiency. The BreathScanŽ breath alcohol detector contains a
crystalline preparation which is hermetically sealed in a glass ampoule. The
subject breathes through the tube so as to deliver approximately two liters
of breath over the crystals. At .00% BAC (no alcohol present) the crystals
remain uniformly yellow. At .05% BAC, some of the crystals turn green.
Above .10% BAC, virtually all the indicators
showed all the crystals turned green. At precisely .10% most of them were
fully changed and a small number were partially changed with only a few
yellow crystals remaining.
