A method of screening air and water samples for the chemical-warfare
agent Sarin is developed using solid-phase microextraction (SPME)–gas chromatography
(GC)–mass spectrometry (MS). The SPME field kit sampler is ideal for collecting
air and water samples in the field and transporting samples safely to the laboratory.
The sampler also allows the sample to be introduced into the GC–MS system
without further sample preparation. Results of the tests with Sarin using the
SPME technique indicate that a sample collection time of 5 min is sufficient
to detect 100 ng/L of Sarin in air. For water samples, Sarin is detected at
a concentration of 12 µg/mL or higher. This method is ideal for screening
samples for quick response situations.
