This study describes the simultaneous direct determination of endothall, glyphosate, AMPA, and glufosinate in
drinking water by IC-MS. The four pesticides can be determined sensitively and accurately using a Dionex
IonPac AS19-4μm column and an ISQ EC single quadrupole mass spectrometer.
This document provides a guide for carrying out the quantitation of volatile and condensable emissions in car trim in accordance with VDA 278, using the combined Thermo Scientific™ / Markes International TD-GC-MS system. In addition to describing the entire TD–GC–MS analytical process, advice on targeted aspects of sample preparation and the analytical procedure are included.
To demonstrate a simple and effective analytical solution for the direct analysis of volatile organic compounds (VOC) and semi volatile condensable compounds (FOG) emitted from car interior trim material referencing base parameters in the VDA 278 method, utilizing the thermal desorption sampling technique coupled to GC-MS and Thermo Scientific™ Chromeleon™ Chromatography Data System (CDS) software for data acquisition, processing, and intelligent reporting against hazardous chemical lists.
This application note (AN) demonstrates the determination of inorganic anions in water samples using a Thermo Scientific™ Dionex™ IonPac™ AS29-Fast-4μm anion-exchange column. The AN also show the benefits of this column compared to a Thermo Scientific™ Dionex™ IonPac™ AS4A-SC column, the column originally specified in U.S. EPA Method 300.0 Part A. It was found that Dionex IonPac AS29-Fast-4μm column has improved selectivity and higher capacity, making it a better choice for compliance monitoring of inorganic anions, especially for high-ionic strength water and other challenging samples.
An alternative chromatographic approach to US EPA Method TO-15 for the rapid determination of toxic organic compounds in ambient air using a combined TD-GC-MS solution from Markes International and Thermo Fisher Scientific.
