“ Storage stability was determined to be at least seven days at room temperature. Breakthrough of the front section of the Porapak Q tube was not observed after sampling 8.1 L of a test atmosphere containing 852 mg/m 3 at ≥ 80% RH for 185 min at 0.044 L/min. Desorption efficiencies for samples spiked with methylcyclohexanone in the range 0.73 to 2.93 mg per sample were 0.91 to 0.94. ”

“ SPECIAL PRECAUTIONS: Acetone, methylcyclohexanone, and n-hexane are highly flammable. All work should be performed in a well-ventilated hood. SAMPLING: 1. 2. 3. 4. Calibrate each personal sampling pump with a representative sampler in line. Remove the end caps from the sampler immediately before sampling. Attach sampler to personal sampling pump with flexible tubing. Sample at an accurately known flow rate between 0.01 to 0.05 L/min for a total sample size of 1 to 6 L. Cap the samplers. Pack securely for shipment. SAMPLE PREPARATION: 5. 6. 7. ”
