Achieve better gas chromatography separations with an appropriate column. Review the most significant factors for gc column selection: stationary phase, internal diameter, film thickness, and column length.
Pistachios contain approximately 45% fat, which can result in a significant amount of coextracted matrix in the acetonitrile extract generated using the QuEChERS procedure. A zirconia based adsorbent significantly reduces coextracted matrix prior to LC-MS or GC-MS.
A sensitive, quantitative, and reproducible SPME-GC/MS procedure was developed by Supelco for the extraction of phthalate esters from oily food matrices, such as the flavored oils included with ramen noodle kits.
Bisphenol A (BPA) plastic is controversial in food and beverage containers. This study demonstrates SPME of BPA from an energy drink using an overcoated PDMS/DVB fiber, followed by GC/MS/MS analysis using SLB-PAHms GC Column.
This article explores the analysis of fats in food and beverage products. From derivatization of fatty acids to FAMEs, to analysis of FAME isomers, and more we are your one-stop shop for all of your food and beverage analysis needs.
The odor and pungency of ginger is due to the presence of terpenes, gingerols and shogaols. These compounds contribute to the highly complex matrix of ginger, which subsequently presents a challenge in low level analyses of contaminants. A novel 2-layer
Pesticide residue testing of turmeric and other (dried) spices is challenging due to their complex compositions and high matrix. An efficient SPE clean-up can be achieved by a new Dual-layer cartridge.
