This method describes the sample collection and analysis of propylene oxide. Samples are collected by drawing air through standard size Anasorb 747 adsorbent tubes. The Anasorb 747 is desorbed with carbon disulfide and the desorbate is analyzed by gas chromatography using a flame ionization detector.

| Hold Times, Preservatives, Preps, Collection, Analytical & Documentation | |
|---|---|
| Holding Time: | Up to 15 days. |
| Preservatives: | Stored samples should be kept at 0°C or colder to reduce migration. Reduced temperature shipment of samples to the laboratory is not necessary. |
| Required Preps: | Samples are collected with solid sorbent sampling tubes containing Anasorb 747: 140mg/70mg. Each tube consists of two sections of Anasorb 747 separated by a urethane foam plug. |
| Collection Method: | Anasorb 747 tube: 5 L at 0.1 L/min. |
| Analytical Methodology: | GC/FID. |
