Scientists from Tabriz University and the University of Tabriz explored cellulose acetate-UiO-66-COOH as an affordable coating sorbent for thin film extraction of biogenic amines from cheese and alcohol-free beverages using HPLC-MS/MS.
Tissue Sample Preparation — Not the Same Old Grind
February 1st 2004Extracting analytes from biological tissues often presents serious challenges for the analytical chemist. In this column, the guest authors provide an overview of human and animal tissue sample preparation, and compare conventional extraction technologies with novel approaches to these challenges.
Selective Sorbents for Solid-Phase Extraction Based on Molecularly Imprinted Polymers
September 1st 2001Highly selective sorbents for solid-phase extraction (SPE) are desirable tools for the development of selective and sensitive methods for trace analysis. Molecular imprinting is an emerging technique that can yield analyte- or group-selective polymeric sorbents.
