Extraction of a Full Suite of Semivolatile Compounds from Drinking Water Using Automated Solid-Phase Extraction

Drinking water is an important part of environmental exposure, especially for small children. Countries around the world have put regulations in place to monitor drinking water quality for a wide range of hazardous compounds.

A Simple Analysis of 4-Methylimidazole Using Automated Solid-Phase Extraction and High Performance Liquid Chromatography with MS-MS and MS–SIM Detection

Modern Hexane-Extractable Material (Oil and Grease) Analysis in Wastewater Samples

Initial precision was demonstrated by spiking four 1-L volumes with one Snip and Pour pre-measured standard, each (40 mg). The data for four replicates was collected for 47 mm Disks and 100 mm Disks. The average percent recovery is excellent and meets the criterion specified of 83–101% HEM recovery for both size disks. The standard deviation is better than the criterion specified of 11% for HEM.
