Observations on ToxTrap silica gel breath capture tubes for alcohol analysis.
Experimental studies were carried out to investigate the accuracy, precision, and reliability of ToxTrap silica gel tubes relative to the capture, from Intoxilyzers, and subsequent analysis of alcohol derived from Simulator vapors or breath samples. Factors influencing analytical results, such as the presence of moisture in the tubes, were investigated. Comparisons were made between immediate, direct Intoxilyzer results and ToxTrap tube results obtained by a gas chromatographic technique.
