AN10451: Determination of Chlorophenols in Water According to U.S. EPA Method 528Instrument Type: GCMS
Phenolic compounds are involved in many industrial processes as either reagents or byproducts. Their ubiquitous presence and widespread use makes pollution with phenols very likely. Waters are particularly impacted and monitoring is necessary to detect this source of pollution as it can represent a serious threat to environmental and human health. U.S. EPA method 528 provides guidelines for the GC-MS analysis of phenols in water. This application note provides a workflow method for determination of chlorophenols in drinking water and can be used for U.S. EPA Method 528.
AN1097: Determination of Pesticide Residues in Drinking Water Using Automated Solid-Phase Extraction and Gas Chromatography with Nitrogen Phosphorus DetectionInstrument Type: GC
This application note addresses the detection of trace amounts of organophosphorus pesticides in water and optimizes the conditions for solid-phase extraction (SPE) and chromatographic analysis using the AutoTrace 280 Solid-Phase Extraction instrument and the Thermo Scientific™ TRACE™ 1300 Series gas chromatograph with a nitrogen-phosphorus detector (NPD).
AN1109: Rapid Determination of Nitrobenzenes in Drinking Water Using Automated SPE with GC-ECDInstrument Type: GC
Nitrobenzenes are precursors for the production of numerous industrial chemicals and may be released into the environment through wastewater discharge and may contaminate ground and surface waters. This AN demonstrates automated SPE with GC-ECD for the determination of 15 nitrobenzene compounds in drinking water. The automated Thermo Scientific™ Dionex™ AutoTrace 280 SPE instrument was used in conjunction with the Thermo Scientific™ TRACE™ 1310 GC.This work optimizes SPE and GC conditions and the results show high sensitivity for the 15 nitrobenzene compounds specified in HJ 648-2013.
Comparing LC and GC Triple Quadrupole MS for the Screening of 500 Pesticides in MatrixInstrument Type: LCMSMS
Modern pesticide analysis is extremely challenging due to the diversity of compounds required to be reported, especially in the area of food safety control. The pressure to report large numbers of pesticides quickly makes it attractive to use large single injection methods. Triple quad MS has emerged as a primary screening technique due to its high sensitivity and selectivity against matrix. Presented is a comparison of both LC and GC sample introduction techniques coupled to triple quad MS screening of over 500 pesticides at ppb levels.
