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 microg/mL or higher. This method is ideal for screening samples for quick response situations.
开发了一种使用固相微萃取（SPME）-气相色谱（GC）-质谱（MS）对空气和水样进行化学战剂沙林筛查的方法。SPME现场试剂盒采样器非常适合在现场采集空气和水样，并将样品安全运送到实验室。该采样器还允许在无需进一步样品制备的情况下将样品引入GC-MS系统。使用SPME技术对沙林进行测试的结果表明，5分钟的样品采集时间足以检测空气中100 ng/L的沙林。对于水样，沙林在浓度为12 μg/mL或更高时可被检测到。该方法非常适合在快速响应情况下对样品进行筛查。
