This paper presents a new LC-MS-MS method for the determination of the concentration of nonylphenol ethoxylates (NPEOs) and nonylphenol carboxylic acids (NPECs) in surface and drinking water using a reversed-phase column, which is fast and specific by nature. This method allows the simultaneous analysis of the two families of compounds in the same extract. Liquid-solid extraction of 100 ml of sample is performed on graphitized carbon black (GCB) cartridges. Reversed-phase chromatography is… CONTINUE READING
