The Effect of Non-Ethanolic Substances on the Alcolmeter S-L2

Pages 131-135 | Published online: 22 Nov 2013
 

ABSTRACT

The specificity of the Alcolmeter S-L2 was examined for any responses from selected non-ethanolic substances which have been used to challenge the accuracy of the Breathalyzer®. Two respiratory inhalers and selected OTC (over-the counter) products were given to human subjects before testing the subjects' breath with the S-L2. Nine common volatile substances: acetaldehyde, acetone, ether, ethylene glycol, isopropanol, methanol, methylene chloride, toluene, and trichloroethylene were sampled on the S-L2 via simulated breath samples. The resulting S-L2 READY, PASS, WARN, or FAIL lights and corresponding digital readings were recorded for each test. The only significant readings were those produced by toxic or lethal levels for acetaldehyde, ether, isopropanol and methanol.

RÉSUMÉ

La spécificité de l'instrument Alcometer S-L2 a été étudiée afin de déterminer si d'autres substances non-éthanoliques, déjà utilisées pour mettre en question l'exactitude du Breathalyzer®, pouvaient produire une réaction. Deux aérosol-doseurs et certains médicaments qui peuvent être obtenus sans prescription ont été administrés à des volontaires avant d'analyser leur haleine à l'aide du S-L2. Le S-L2 a été mis à l'épreuve à l'aide d'échantillons d'haleine simulés pour neuf substances volatiles communes: acétaldé- hyde, acétone, éther, glycol d'éthylène, isopropanol, méthanol, chlorure de méthylène, toluène et trichloroéthylène.
