Sitelab’s GRO calibration kit, CAL-025, is used to measure volatile petroleum hydrocarbons in the C6 to C10 range. This test matches well to U.S. EPA and other regulatory methods for GRO, BTEX, VPH or VOCs using GC/FID instrumentation.
The UVF-TRILOGY and UVF-3100 analyzers are fitted with similar optical filters and produce accurate results over a wide range of contaminants. Samples only take a few minutes to extract in solvent and analyze. Minimum detection limit is 0.5 ppm.
