Method 525.3

Method 525.3 was developed by the US EPA for the determination of semi-volatile organic chemicals in drinking water. This is an analytical method that uses solid phase extraction (SPE) and gas chromatography/mass spectrometry (GC/MS) for the identification and quantitation of 123 selected compounds. These compounds range from polychlorinated biphenyls (PCBs), poly aromatic hydrocarbons (PAHs), and pesticides. The standards can be purchased individually or as a complete set for your laboratory's particular needs. Additionally, the required surrogate and internal standards are also offered.
