Double 11 Stocking Guide - Agilent Gas Chromatography Column Fatty Acid Analysis Scheme
Date: 2025-11-06Read: 0
In the pharmaceutical industry, gas chromatography plays a key role in quality control such as residual solvent detection, excipient content determination, related substances, and fatty acid composition. In the field of food testing, in order to improve processing efficiency, flavor, taste, and extend shelf life, precise analysis of fatty acid methyl esters, fatty acids, and triglycerides in products is necessary.
Lipid excipient testing
Sterol determination: LC silica gel column separation+DB/HP-5ms UI
Fatty acid composition: Polyethylene glycol column (DB-FATWAX UI)
Trans fatty acid: Polydicyanopropylsiloxane (100m x 0.25mm x 0.20 μ m)
relevant standards
food testing
The most common analytical method is indirect analysis of free fatty acids or fatty acid methyl esters (FAME) using gas chromatography. The direct analysis methods for triglycerides, monoglycerides, and diglycerides also provide new ideas for the characterization of fats and oils, and can be used in conjunction with analysis methods for cholesterol and other lipids.
Used for fatty acid and oil analysis
Agilent's complete product line
Each Agilent J&W gas chromatography column undergoes strict industry QC standard testing in terms of column loss, sensitivity, and column efficiency, providing you with the most reliable qualitative and quantitative analysis results.
