3.6 Sample Analysis and Management
Laboratories Utilized and Analyses Performed Inorganic analyses, which included MMVF, alpha-quartz, calcite, gypsum, lead, total dust, pH and total particulates not otherwise specified (NIOSH 0500) were performed by EMSL Laboratories (EMSL), at the corporate headquarters located at 107 Haddon Avenue, Westmont, NJ. The analyses for asbestos using PCM, PLM, and TEM were performed by EMSL Laboratories, 307 West 38th St., New York, NY. Organic analyses were provided by Paradigm Analytical, 2627 North Chase Parkway SE, Wilmington, NC. These analyses included PAH and DioxinsZFurans.
’’Pump flow rates were measured before and after sample collection. Pumps were calibrated before each use and the flow rate was confirmed following the sample period. A primary dry cell calibrator (BIOS DC-Lite) was used to establish the flow rates of the SKC person^ sampling pumps. A GiIibrator-2 High Flow Wet Cell Calibrator was used to establish the flow rates of the AirCon-2 high volume air samplers. Calibrating for alpha quartz, calcite, gypsum and dioxins/fiirans also required separate flow chambers. Flow rates were recorded on Air Sampling Data Sheets.
