One-Step Extraction and Concentration for Identifying Pharmaceuticals and Personal Care Products in Water, Biosolids and Solids
Tom Hall, FMS, Inc.
The scope of human exposure to Pharmaceuticals and Personal Care Products (PPCPs) from the environment is complicated and increased monitoring is occurring to determine the effect on humans of long-term, low-level exposure to PPCPs. Due to their persistent nature and toxicity,monitoring water sources for PPCPs is a growing priority for both government agencies and consumers. The following procedure outlines the fully automated, sample-to-vial extraction and concentration of water matrices for the detection of these compounds in one rapid and efficient process. |

High Efficiency, Quantitative Dioxins Screening at the Level of Interest in Feed and Food using Advanced GC-MS/MS
Paul Silcock, Dirk Krumwiede, Inge de Dobbeleer, Hans-Joachim Huebschmann, Thermo Fisher Scientific
Current European Union regulations permit the use of GC-MS/MS and bioassay techniques for screening dioxins and dioxin-like PCBs at the level of interest in feed and food samples. GC coupled with triple quadrupole MS is particularly suitable screening technique as isotope dilution is retained as well as the high selectivity of the MS/MS experiment. This application note describes the use of a GC-MS/MS as applied to high efficiency screening of PCDDs/PCDFs in feed and food samples. at the levels of interest and the level of confirmatory analysis using GC-HRMS. |
