Sorbent trap samples are collected at the sorbent trap station of the sampling manifold. Sorbent traps are pencil-size stainless-steel or glass tubes that contain vapor-adsorbing media. through the tube, which traps (by adsorption) virtually all the target analytes. The concentration of analytes in the vapor sampled is calculated from the quantity of analyte found in the sorbent media and the volume of vapor passed through the sorbent trap.

The sorbent trap station uses highly accurate mass flow controllers to measure and control the flow rate of sample vapor through the sorbent traps. The controllers FICV-1 through FICV-9 are mounted on top o f the sorbent station between the inlet and outlet valves. Controllers FICV-10 and FICV-I1 are located downstream of the sorbent trap station and the in-line driers, which remove moisture from the sample vapor before it i s metered. with the mass flow controllers were determined by the Westinghouse Hanford Company (WHC) Standards Laboratory before the SST 241-SX-105 sampling event (see Table 1). analytical 1 aboratories that supply and analyze the sorbent traps.

G. S. Caprio, VSS Technician R. D. Mahon, VSS Lead Scientist T. B. Utecht, VSS Technician R. A. Westberg, Field Scientist.

The VSS was set up at SST 241-SX-105 on July 25, 1995 and was allowed to warm up overnight. was completed by 12:OO p.m. the same day.

Sampling began shortly after 8:OO a.m. on July 26, 1995, and

3.3 INDUSTRIAL HYGIENE FIELD RESULTS

Before hooking up to SST 241-SX-105, an industrial hygiene technician field tested tank vapors. 5 minutes and then field measured vapor stream contents using a combustible gas indicator (CGI) and an organic vapor meter (DVM). verbally reported, LEL 056, NH, 0 ppm, O2 20.9%, and TOC 0.0 ppm.

The technician purged the vapor probe sample tube for

3.5 SAMPLE COLLECTION

The hot-water-jacketed sampling probe was located in Riser R11 of SST 241-SX-105. flange, was 7.3 meters.

All zones of the VSS were heated to 60 "C during setup of the VSS at SST 241-SX-105 on July 25, 1995. 8:OO a.m. on July 26, 1995, and the system was ready to collect samples. Measured according to the VSS operating procedure, the pressure and temperature of SST 241-SX-105 were 985 mbar (739.1 torr) and 35.4 "C, respectively. The sample log sheets in Appendix A provide a complete chronology of the sample event including start and end times, flow rates, volumes, and specific sample identifiers.

Approximately 17 hours before the first samples were collected, the team began heating the VSS transfer tubing and sampling manifold. period, the team began a purge o f all vapor transfer tubing and the sampling manifold with ambient ai;. Before sampling tank vapors on July 26, 1995, the team collected two SUMMA canister samples of ambient air, one manually

10 meters upwind of the VSS connection with SST 241-SX-105, and the other using the VSS sampling manifold. background levels o f trace organic vapors, and the latter was collected to establish the cleanliness of the sampling manifold.

A leak check of the VSS sampling manifold and transfer tubing (up to the connection to the sampling probe) was performed prior to opening the tank probe vapor sampling valve. The system was evacuated to 284 mbar (212.7 torr) and leakage of ambient air into the system was observed by monitoring system pressure for 15 minutes. Leakage resulted in an increase of 3.9 mbar (2.9 torr) in system pressure during t h e 15 minute test. Given a system volume of not more than 10 L, this pressure increase corresponds to a leak rate of approximately 9.1 mL/min. This leak rate was then estimated for average SUMMAT”, triple sorbent krap (TST), and sorbent sampling pressures. It was found that for the SUMMA canisters, dilution by ambient air was approximately 0.1%, for TSTs sampled at 200 mL/min the dilution was approximately 0.3%, and for sorbent traps the dilution was approximately 0.3%.

The tank probe vapor sampling valve was opened and the VSS was purged with sample vapor from SST 241-SX-105 for 30 minutes at a total flow rate of 5.46 L/min. This purge was performed to flush ambient air from the system and saturate the system’s active adsorption sites. Because the volume of transfer tubing and the sampling manifold upstream of the sampling devices i s estimated to be no more than IO L, this purge provided about 16.4 air turnovers in the system.

One analytical 1aborNatory provided sample media. (PNL) provided SUMMA canisters, TSTs, and sorbent traps for organic vapors, ammonia (NH,), nitrogen dioxide (NO2), and water vapor (H,O).
