We recently stocked custom EPA Method 530 standards made specifically for labs participating in Unregulated Contaminant Monitoring Rule 4 (UCMR4). Quantitative Certificates of Analysis with Data Packs are available for each item.

Cat# 572262 – Method 530 UCMR4 Standard (in Methanol)

Cat# 572265 – Method 530 UCMR4 Surrogate Standard (in Methanol)

Cat# 572266 – Method 530 UCMR4 Internal Standard (in Acetone)

The suggested analytical column for EPA Method 530, the Determination of Select Semivolatile Organic Chemicals in Drinking Water by Solid Phase Extraction and Gas Chromatography / Mass Spectrometry, is the Rtx-1701, though “any capillary column that provides adequate capacity, resolution, accuracy, and precision may be used.” 3 of the 4 Method 530 target analytes, butylated hydroxyanisole, o-toluidine, and quinoline have been included in UCMR4; dimethipin, the 4th target analyte, was included in UCMR4 as part of EPA 525.3. I’ve included example chromatograms collected at the method reporting limit (MRL) and at 10x the MRL below. The GC inlet, oven and detector settings were taken directly from the method, and the AutoSIM function in MSD Chemstation version D.03 was used to generate the SIM analysis windows.
