This application note describes a non-targeted metabolomic analysis approach to the classification of wine varieties, employing LC/QTOF MS and MassHunter Workstation software. Molecular feature extraction, data filtering, and statistical analysis utilizing ANOVA and PCA identified 26 marker compounds that were then used to build a PLSDA prediction model. An overall accuracy of 95.6% in discriminating between Cabernet Sauvignon, Merlot and Pinot Noir red wine varieties was obtained using the model. This approach may be widely applicable to the analysis and characterization of foods.

This document describes the method of fast separation of oxygen and nitrogen using Agilent 490 Micro GC and a 4 m MolSieve 5A column channel. The Agilent 490 Micro GC has the advantages of ease of use and fast analysis.

The document describes the method of analyzing amitriptyline, fluoxetine, quetiapine, and sertraline using dried blood spots. Blood is spotted onto a blood spotting card and allowed to dry, then samples are taken from the spot for analysis. A new non-cellulose material can also be used for other biological fluids. The use of dried blood spot analysis for drugs is gaining popularity in clinical trials in the pharmaceutical industry.

This application note describes the use of the 490 Micro GC for the analyses of mine gas, especially carbon monoxide at low level, detection of which is essential for the safety of mine workers. Three independent GC channels analyze the sample in less than two minutes, including permanent gases and C1-C2 hydrocarbons.

This application note describes a method for analyzing fullerenes using Agilent PLgel columns and gel permeation chromatography.

This application note describes a method for analyzing phenolic resins using Agilent PLgel columns and gel permeation chromatography. The method can be used to analyze various types of phenolic resins, including those used in printed circuit boards, adhesives, coatings, and laboratory bench tops.

This application note describes how to use Agilent PLgel for the gel permeation chromatography analysis of silicone oils.

This article describes the analysis of oligosaccharides using gel permeation chromatography on Agilent PLgel. NMP is used as the solvent, allowing for the analysis of more polar oligosaccharides such as starch. The viscosity of NMP is extremely high, and operating at elevated temperature is recommended to reduce pressure and enhance resolution.

The application note shows the analysis of Tetrahydrothiophene (THT) in a Natural Gas matrix using the Agilent 490 Micro GC.

This application note investigates the ability of the Agilent Fish ID solution to detect mammalian or avian DNA using meat samples.
