“ Calculate concentration, C, analyte in the air volume sampled, V (L) :
EVALUATION OF METHOD: Method S38 for methyl acrylate was issued on 12/6/74, and evaluated over a range of 13.9 to 58.4 mg/m 3 at an atmospheric temperature of 23°C and a pressure of 764 mm Hg, using 6-L samples [1] . Breakthrough was determined by sampling a generated atmosphere at a concentration of 59 mg/m 3 for 240 min at a flow rate of 0.190 L/min. Desorption efficiency (DE) was determined by spiking charcoal tubes at three levels, 0.087, 0.175, and 0.350 mg of methyl acrylate. ”

“ Methyl Acrylate, ACS reagent grade. Helium, purified. Hydrogen, prepurified. Air, compressed, filtered.
1. Sampler: glass tube, 7 cm long, 6-mm OD, 4-mm ID, flame-sealed ends, containing two sections of activated (600 °C) coconut shell charcoal (front = 100 mg; back = 50 mg) separated by a 2-mm urethane foam plug. A silylated glass wool plug precedes the front section and a 3-mm urethane foam plug follows the back section. Pressure drop across the tube at 1 L/min airflow must be less than 3.4 kPa. Tubes are commercially available. 2. ”
