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 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 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.

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 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.

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 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.
