Ultrapure Water Essential for Direct Determination of Bisphenol A by HPLC -MS/MS
9 Jun 2013Until recently, bisphenol A (BPA) was widely used in the manufacture of polycarbonate plastics and epoxy resins, and the risks associated with BPA remain highly controversial. As a result, numerous determinations of trace BPA are now carried out, creating the need for robust analytical processes. In this application note read how high performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) offers extremely high sensitivity for BPA detection and how ELGA® pure water systems offer effective removal of BPA.

Water PurificationThere are a number of water purification methods available to remove contamination from laboratory water. These systems include demineralization, reverse osmosis, filtration and ultrafiltration. A combination of methods is sometimes necessary to achieve purified water suitable for use in experiments.Ultrapure WaterUltrapure water is the highest purity water and contains the lowest levels of organic and inorganic contaminants, particulates and microorganisms.Water AnalysisAnalytical methods used to test the purity of drinking water include determining the level of contaminants abides to the level set by the Environmental Protection Agency (EPA).
