PCM, PLM, and Mold analyses are performed on-site in our laboratory, which is NVLAP (Lab code 200515-0) and AIHA-LAP, LLC (Lab ID# 102666) accredited.
Phase Contrast Microscopy (PCM) is primarily used for estimating asbestos concentrations in air, though not differentiating between asbestos fibers and other fibers using NIOSH Method: 7400 but also used for the specific non-asbestos fiber measurements of fibrous glass.
Polarized Light Microscopy (PLM) is used for detection of asbestos fibers using EPA 600/R-93/116: Method for the Determination of Asbestos in Bulk Building Materials and EPA 600/M4-82-020: Interim Method for Determination of Asbestos in Bulk Insulation Samples. Microscopists can distinguish asbestos fibers from non-asbestos fibers utilizing specific optical properties.
Fungal Spore Identification of Air, Bulk, and Surface Direct Examination by Optical Microscopy using ASTM:D7381-17 and ASTM:D7658-17 supplemented by ALS-110, 111, and 112. Microscopists are highly trained in fungal spore identification and must maintain satisfactory performance in all proficiency testing.
OTHER LABORATORY ANALYSIS
Organic and inorganic chemicals, metals, silica dust, priority pollutants, TCLP, and a full range of specialized analysis are provided at off-site laboratory facilities.
