Abstract
The development of a method for sampling and analysis of airborne 2-nitropropane is described. The 5% breakthrbugh volumes of several sorbents for the analyte were determined using a challenge atmosphere of 10 ppm (36 mg/m3) 2-nitropropane in humid air at a flow-rate of 0.2 liter/minute. Chromosorb 106 (60/80 mesh), a cross linked polystyrene porous polymer, had the highest capacity - 10.4 liters. Samples collected on Chromosorb 106 were desorbed with ethyl acetate and analyzed by gas chromatography using a flame ionization detector. Recovery was quantitative at or above the 10 µg/sample level. The precision of analysis was 0.05 relative standard deviation for eighteen 3-L samples of 2-nitropropane taken from humid atmospheres over the range 1.0-10 ppm (3.6-36 mg/m3).This publication has 0 references indexed in Scilit:
