| Sampling group | |
| Sampler/Sampling media | 2 Specially dried silica gel tubes in series; each tube has a single 600 mg section and a GFF, filter faces forward when sampling [SKC 226-183] |
| Sampling time* | 200 min |
| Sampling volume (TWA)* | 10 L (9 L if also sampling for diacetyl and/or acetoin) |
| Sampling flow rate (TWA)* | 0.05 L/min |
| Sampling volume (STEL/Peak/C)* | 3 L |
| Sampling flow rate (STEL/Peak/C)* | 0.2 L/min |
| Analytical method instruments | GC-FID |
| Method reference | OSHA 1016 (fully validated) |
| Notes | Use an opaque tube holder or wrap tubes with aluminum foil or other opaque material while sampling. Separate the 2 tubes and cap both ends of each tube as soon as possible after sampling. Individually seal the 2 tubes. Protect tubes from light after sampling.
|
| Special requirements | Samples should be kept cold and shipped cold to the lab by overnight shipping as soon as possible. |
* All sampling instructions above are recommended guidelines for OSHA Compliance Safety and Health Officers (CSHOs), please see the corresponding OSHA method reference for complete details.
