Field Test Reagents for PCB in Transformer Oil


On-Site Test Reagents for PCB Analysis in Transformer Oil

The L2000DX PCB/Chloride Analyzer is field portable, designed to screen dielectric fluid for PCBs, on-site, at a much lower cost than laboratory methods. The L2000DX PCB/Chloride Analyzer can reduce the number of laboratory samples by as much as 80%. The resultant chloride is measured with an ion specific electrode and the chloride reading is converted to ppm PCB by the L2000DX. Total testing time is less than 5 minutes per test. The L2000DX can quantify PCB in dielectric fluid from 2 ppm to 2000 ppm.

The L2000DX analyzer is preprogrammed with conversion factors for all major Aroclors. The precanned programs are easily selected from a menu to perform routine analysis. The built-in methods include corrections for extraction efficiencies, dilution factors and blank contributions.

The oil sample is reacted with a sodium reagent which strips the covalently bonded chlorine from the PCB molecule. The resulting chloride can then be measured by the ion specific electrode. The raw chloride reading is then converted to ppm of PCB. Analysis results are displayed on the LCD screen, but can also be stored for later print-out; up-loaded to a PC via the RS-232 serial port or sent directly to the on-board 40 column thermal printer. The on-board printer can be programmed to print customized information such as user name and sample number.

The usable measurement range for transformer oil is (MDL) 2 ppm to 2000 ppm.

NOTE: This test method is used for testing DIELECTRIC FLUID (transformer oil) ONLY. It cannot be used to determine PCB contamination of other types of used oils (i.e. used motor oil or other types of lubricants/industrial oils).
