“ Calibrate each personal sampling pump with a representative sampler in line. Add 15 mL isooctane to the bubbler. Sample at 0.5 L/min for 1 to 6 hrs (30 to 180 L) . NOTE: Check liquid level in the bubbler every 15 min. Maintain between 10 and 15 mL isooctane in the bubbler throughout the sampling period with a volume at the end of sampling of about 10 mL. Remove the bubbler stem and tap it gently against the inside wall of the bubbler to transfer solvent from the stem to the bubbler. Transfer contents of the bubbler to a vial. Rinse the bubbler with 2 mL isooctane. Add the rinse to the vial. ”
