Application Note: EPA Method 530: Determination of Selected Semivolatile Organic Chemicals in Drinking Water by SPE and GC/MS
19 June 2017
Recently the US EPA published a list of 30 UCMR4 (the 4th Unregulated Contaminant Monitoring Rule) analytes which may potentially be present in tap water but are not yet subject to EPA’s drinking water standards set under the Safety Drinking Water Act. 4 among the 30 UCMR4 compounds, including o-toluidine, quinoline, butylated hydroxyanisole (BHA), and dimethipin, are determined by EPA method 530 using solid phase extraction (SPE) and GC/MS detection. This application method demonstrates the analysis of a sample of preserved drinking water using SPE and GC/MS.
