L2000DXT PCB Test Reagents for Surface Wipe Samples
The L2000DX Analyzer System offers environmental testing versatility including PCB testing of surface wipe samples. If waiting for laboratory results for surface wipes is not an option, the L2000DX system can provide on-the-spot screening in just a few easy steps with results in less than 10 minutes. This test method requires wiping an area 1000 cm2; results are provided in µg PCB/100 cm2 . Results are not specific to any Aroclor, they are determined by extracting and quantifying the chlorine associated with PCBs. The amount of chlorine is directly proportional to the amount of PCB.
Collected wipe samples are extracted and reacted with a sodium reagent to strip the covalently bonded chlorine from the analyte(s) converting it to inorganic chloride. The resulting chloride is then detected and quantified using a chloride ion specific electrode. The L2000DX then mathematically converts the chloride reading to the equivalent concentration of the target analyte based on the percent chlorine associated with the analyte. Conversion programs are available for all major Aroclors and most common chlorinated solvents and pesticides. Custom conversion programs can be built for less common analyte(s) not included in the L2000DX menu, instructions are included in the user manual.
The usable result range for the L2000DX is (MDL) 3 ppm - 2000 ppm. Results are displayed on the LCD screen and printed by the on-board thermal printer. The printed record can be customized to include project specific information such as site location, sample ID, technician’s name, etc. The L2000DX also stores the test data for later recall or reprinting.
In addition to test reagents, each wipe reagent pack include everything needed to collect 20 wipe samples; gauze pads, individually sealed glass ampules containing chromatographic hexane, sample vials, as well as PCB rated gloves and plastic goggles for safety.
