LGC Standards' new PCB reference materials facilitate EPA compliance

Date:12 September 2011

LGC Standards, Europe's leading supplier of reference materials, has expanded its range of polychlorinated biphenyls (PCBs) and related compounds from ULTRA Scientific to include the five PCB congener mixtures and the native toxins/level of chlorination (LOC) stock solution required by EPA Analytical Method 1668A and 1668B.

PCBs are a class of organic compounds known to be the most persistent and widely distributed pollutants in the environment. EPA Method 1668A is used to determine the presence of PCBs in water, soil, sediment, bio-solids, tissue and other sample matrices by high resolution gas chromatography or high resolution mass spectrometry.

Where a laboratory prepares its own calibration solutions, there is potential for contamination because background levels of PCBs can be higher than the concentrations of PCBs in the calibration solutions. EPA Method 1668B specifies that these solutions should be manufactured in a chlorinated biphenyl contamination-free environment. If these requirements cannot be met, it further states that the laboratory should 'have a vendor prepare the calibration standards and guarantee freedom from contamination'.

LGC Standards meets this requirement by offering these PCB congener mixtures to laboratories as a reliable, ready-to-use standard, guaranteed free from contamination. These PCB mixtures are manufactured by ULTRA Scientific in accordance with ULTRA's ISO 9001 registered quality system and with the analyte concentrations verified by ULTRA's ISO 17025 accredited laboratory.
