Prepared for use in a breath alcohol simulator which is capable of controlling
the solution temperature at 34 ± 0.2°C. When air (breath) is bubbled through
this solution, an equivalent BAC is generated based upon the 2100: 1 Breath
- Blood Alcohol Ratio.
Absolute ethyl alcohol (USP Grade) is mixed with distilled water to provide
an analytical concentration predictive of the equivalent BAC as noted
above. For example, a 100 mg% (0.10%) would have an analytical concentration
of 1.21 mg/mL. A tolerance of 0.00 to +0.02 mg/mL is maintained.
Each batch of solution is independently analyzed by gas chromatography
using the internal standard technique. The certification process also
includes a simulator test using a Breathalyzer model 900/900A and an Intoxilyzer
5000. A certificate is available upon request.
The solution is bottled in high-density polyethylene bottles and closed
with a poly seal cap. A neck seal is provided for integrity.
Ethyl alcohol standard solutions are available in standard concentrations
to provide alcohol breath instruments with the following readings: 0.04%
BAC, 0.05% BAC, 0.10% BAC, and 0.15% BAC. Other concentrations are available.
Each batch of standard solution is given a unique lot number and is further
identified by the equivalent BAC value (e.g. 0.10% BAC), the date of manufacture
and the expiry date for use. Each bottle and each box of six (6) bottles
is so labeled.
