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

This application note describes the interference-free analysis of 16 PAHs listed in EPA 610 using the J&W Select PAH GC column.

This article describes the method for analyzing seven nitrosamines in the MS/MS configuration using the 220-MS Ion Trap GC/MS system and V:Results GC/MS software.

This document is an application note about the use of the Varian 210-MS ion trap mass spectrometer and V:Results™ GC/MS software for gas chromatography mass spectrometry analysis. The method is applicable for the determination of volatile organic compounds in various solid waste samples, including different water content samples such as air sampling trapping media, ground and surface water, aqueous sludges, caustic liquors, waste solvents, oily wastes, mousses, tars, fibrous wastes, polymeric emulsions, filter cakes, spent carbons, spent catalysts, soils, and sediments.

This note provides a basic overview of 25 key regulated compounds rapidly set up on the 210-MS Ion Trap GC/MS system for the analysis of water samples by EPA Method 525.2.

This application note describes a method using the Varian 220-MS ion trap mass spectrometer (Figure 2) to determine melamine and its analogs qualitatively and quantitatively based on the framework of the original FDA method.

This document describes the method of fast fingerprint analysis of perfumes using Agilent J&W FactorFour VF-WAXms high efficiency GC columns. The column shows excellent selectivity for the volatiles present in perfumes and allows significant reduction in analysis time without compromising on resolution of separation.

This document is an application note on the analysis of ylang oil using VF-WAXms GC columns. The components and characteristics of ylang oil samples are analyzed and identified.

This document describes the application of GC/MS analysis of brominated diphenylethers and brominated biphenyls (flame retardants) following ROHS guideline. It includes information on the technique, instrument setup, sample preparation, and peak identification.

This paper describes maximum sensitivity in the analysis of parabens using low temperature ELSD.
