This application note demonstrates the performance of the VF-1701ms with EZ-Guard in the separation of pesticides.

This document describes the GC analysis of base/neutral compounds using an Agilent J&W FactorFour VF-17ms column with EZ-Guard. The EZ-Guard is an integrated guard column that optimizes system uptime and extends column lifetime. The document also provides specific experimental methods and results discussion.

This document describes the GC analysis of PAHs using an Agilent J&W FactorFour VF-17ms column with EZ-Guard. The EZ-Guard is a protective device used to trap non-volatile components from the sample matrix to restore column performance. The document also demonstrates the selectivity of the VF-17ms column in analyzing these important pollutants.

This application note describes a method for analyzing all 136 tetra- through octa- polychlorinated dibenzo-p- dioxins and dibenzofurans using an Agilent J&W FactorFour VF-Xms GC column. This method does not require a second column and allows separation of 16 out of 17 2378-substituted dioxins and furans from other close-eluted isomers.

This document describes the separation of fatty acid methyl esters (FAME) on an Agilent J&W Select CP-Sil 88 column. The column has a high polarity liquid phase, which effectively differentiates between multiple FAME isomers.

This application note describes a method for authenticating Scotch whisky using GC analysis. The method involves analyzing the alcohol components in the whisky to determine its authenticity.

A sensitive and reproducible gas chromatographic method for ethanol and other volatile organic compounds in serum or plasma was developed using the polar CP- Wax 52 CB column, creating good peak shapes; this can also be seen for ethylene glycol.

This article introduces the widespread use of fatty acid monoamides as slip agents (lubricants) in the production of polymeric films and as anti-adhesives in the food industry. The advantage of using fatty acid monoamides is their biodegradability. Unsaturated amides show better performance than saturated analogues. Some of these amides are also endogenous bioactive substances and cause sleepiness. The authors separated saturated and unsaturated fatty acid monoamides using GC-Capillary Wide Bore technique.

This document describes the analysis of antioxidants and UV absorbers using an Agilent J&W FactorFour VF-5ht UltiMetal column. Engineering plastics and other polymers used for consumer goods and technical applications often contain many additives that significantly influence the final properties of these products. Therefore, the quantitative determination of additives is important to provide a complete compositional analysis.

This document describes the method of high temperature simulated distillation analysis according to the IP507/07 standard. The method is applicable to petroleum products with a vapor pressure low enough to permit sampling at ambient temperature and a boiling range of at least 100 °C. The document provides detailed information on the instrumentation and software used.

This application note illustrates the successful use of an Agilent J&W FactorFour VF-17ms column from Agilent Technologies, Inc. for the fast GC/MS analysis of most PAHs listed in the EU and EPA regulations.

This article describes the method of analyzing volatile amines using the Agilent J&W Select CP-Volamine GC Column. The column is coated with a base deactivated non-polar siloxane type stationary phase, which provides a highly inert coating surface with minimal absorption for difficult basic compounds. The column exhibits good peak shape and excellent stability, making it suitable for the analysis of highly volatile and basic substances.

This document describes a method for using GC/MS to analyze off-flavors in wine

This application note describes the use of the Varian PIONA+™ Analyzer for the fast analysis of paraffins, iso-paraffins, naphthenes and aromatics in hydrocarbon streams.
