Emission Test Report <br /> EMC WA-2-08 <br /> Section 4 <br /> Revision: 0 <br /> Date: September 30,IM <br /> Page 4 of 9 <br /> Sample recovery procedures followed those specified in the method, i.e., using acetone <br /> and methylene chloride for rinsing train components. The toluene QA rinses were also <br /> analyzed for dioxins and furans. The condensate collected in the impingers was not <br /> recovered. All samples were stored and shipped cold at water ice temperature. <br /> 4.1.6 Sampling for Metals <br /> Method 29 in Appendix A of 40 CFR 60 (basis for SOP MRI-8405) was used to <br /> collect samples for metals analysis. Clarifications of and modifications to the method are <br /> also included in the following discussion. <br /> Quartz glass nozzles and probe liners were used in water-cooled probes. The internal <br /> surface of the compression fittings used for connecting nozzles to probe liners are <br /> permanently coated with abrasion-resistant Teflong to prevent sample gas contact with the <br /> stainless steel, and the connections are positioned within the water-cooled section of each <br /> probe. <br /> Heat traced, %-inch O.D. with I/a- inch wall Teflong tubing was used as a sample <br /> transfer line (STL) between the probe liner outlet and the filter holder inlet in all of the <br /> trains because the proximity of adjacent test ports and other obstructions would not allow <br /> sampling with trains assembled in the normal manner. A glass coupling was used to <br /> connect the STL tubing to the probe liner outlet while the other end of the tube was <br /> connected directly to the filter holder inlet. The STL was maintained at 248±25°F during <br /> sampling. Samples were recovered from the STL in the same manner as for the probe, as <br /> specified in Method 29. <br /> No cyclone/flask assembly was necessary in front of the filter holder to prevent <br /> overloading the filter. Filter supports in the filter holders were 100% Teflong. Quartz <br /> fiber filters having the same specifications described in the method were used. <br /> Two silica gel impingers were used in each train. This was done to minimize any need <br /> to swap those components during a test run. <br /> Sample recovery procedures followed those specified in the method. Adequate <br /> quantities of recovery reagents uwd during recovery were saved for analysis for blank <br /> correction purposes. All samples were stored cold at water ice temperature at the test site <br /> (not required by the method), but were shipped and stored at the laboratory at room <br /> temperature. <br /> NM-AMMZ4951-08-03 s4.")d <br /> i <br />
