A method for sampling and analysis of 2-nitropropane in air.
Am Ind Hyg Assoc J 1981 Jan; 42(1):18-22
A sampling and monitoring method was developed for airborne 2- nitropropane (79469). For breakthrough experiments 100 milligram (mg) beds of 12 sorbents were challenged at 200 cubic centimeters per minute with 36mg per cubic meter of 2-nitropropane in humid air. Chromosorb 106, a cross linked polystyrene porous polymer, had the greatest capacity, which was 10.4 liters for 2-nitropropane. Samples collected on Chromosorb 106 were desorbed with ethyl-acetate and analyzed via gas chromatography. The overall sampling and analytical precision was 0.05 for 2-nitropropane samples within the range 1.0 to 10 parts per million, and recovery was quantitative at or above 10 micrograms per sample.
