THE . SAMPLE CAPTJlRE OPTION
The Intoxilyzer SOOOR breath analysis instrument uses a nondestructive infrared absorption technique to find the alcohol concentration of a breath sample.
Consequently, one may preserve the alcohol in an analyzed sample by evacuating the contents of the sample chamber through a tube containing a desiccant, such as silica gel.
Since the desiccant collects alcohol, i t enableso~e to reanalyze a breath sample at a later date.
Some alcohol-capture techniques channel the analyzed sample through the collector tube' and into the room.
Occasion-ally,
-passing the breath sample, through the collector tube only once fails to trap all of the alcohol - a phenomenon known as blow-by.
Therefore, ,to prevent blow-by, the Intoxilyzer SOOOR breath analysis instrument recirculates an analyzed sample through the collector tube until no alcohol remains in the sample.
Following a breath test, the instrument automatically purges the sample chamber.
During a purge operation, the instrument's pump forces the breath sample out an exit port by sucking room air into the sample chamber through the breath tube.
following a breath test, one may preserve the alcohol in
Therefore, a breath sample by connecting one end of a collector tube to the sample chamber's exit port and the other end of the breath tube.
Thus, during the purge operation, the instrument's pump circulates the breath sample instead of exhaust1ngit into the room.
While the desiccant collects the alcohol and water present in the breath sample, the instrument's display shows "AIR BLANK" and a three digit (optional 2 digit) number.
The number is the alcohol concentration present in the sample chamber converted to an equivalent blood/breath alcohol concentration in percent weight by volume.
consequentl~,asthe desiccant traps' the alcohol, the number displayed with "AIR BLANK" decreases.
, "AIR BLANK .000," then-,indicates that the desiccant has captured all the alcohol.
.Following is the order of statements and commands given by the instrument's display when the Intoxilyzer SODOR breath analysis instrument is set with the Sample capture option activated (56

"PLEASE BLOW .###" followed by "PLEAS~ BLOW 0.###"
In order to provide a minimum acceptable breath sample, a subject must blow for a minimum of approximately 6 seconds.
As the subject blows into the mouthpiece, the instrument sounds a continuous tone and displays the message

The continuous tone tells you the subject is blowing with sufficient pressure.
When the zero appears before the
BAC/BrAC value {O.###}, the subject has delivered a minimum acceptable breath sample.
Do not instruct the subject to stop blowing when the zero appears.

If the subject stops blowing before providing a minimum acceptable breath sample,
