EQUIPMENT:
1. Sampler: Thermal sampling tube, ¼” s.s. tube,multi-bed sorbents capable of trapping organic compounds in the C -C range. Exact sampler configuration depends on thermal desorber system used. See Figure 1 for example.
2. Personal sampling pump, 0.01 to 0.05 L/min, with flexible tubing.
3. Shipping containers for thermal desorber sampling tubes.
4. Instrumentation: thermal desorption system, focusing capability, desorption temperature
appropriate to sorbents in tube (~300 C), and interfaced directly to a GC-MS system.
5. Gas chromatograph with injector fitted with 1/4"column adapter, 1/4" Swagelok nuts and Teflon
ferrules (or equivalent).
6. Syringes: 1-μL, 10-μL (liquid); 100-μL, 500-μL (gas tight)
7. Volumetric Flasks, 10-mL.
8. Gas bulb, 2 L
