“ Methanol is flammable and a dangerous fire and explosion risk. It is moderately toxic by ingestion and inhalation. Isopropanol is flammable and a fire risk. Wear appropriate protective clothing and work with these compounds in a well ventilated hood. ”

“ The atmospheres were generated by calibrated syringe pump. Desorption efficiency (DE) was determined to be 0.92 at 1.3 mg methanol and 0.84 at 0.65 mg methanol per sample. The breakthrough volume was 10.4 L (5% on back section) when sampling 3 a methanol atmosphere containing 541 mg/m in dry air at 0.2 L/min for 52 min. Data gathered using larger silica gel tubes (700 mg front section) under conditions of high humidity were published in P&CAM 247 [4] . ”

“ Under the GC parameters stated in the method, methanol may be identified based upon retention time and quantified. The working range is 0.4 to 1200 mg/m3 (0.3 to 916.0 ppm) for a 5-L air sample [1] . At high concentrations of methanol or under conditions of high relative humidity, a large silica gel tube (700 mg) is required [2] . ”
