An international team of researchers has developed a liquid-liquid extraction method for extracting the residues of three drug compounds from samples of eel, flatfish and shrimp bought from a market.

Chinese scientists have developed a novel extraction method based on dispersing unsupported polymer fibers into an analyte-containing solution and then extracting them with tweezers as a single mass.

Chemists in Iran have developed a filter‐based emulsification microextraction method for extracting amphetamine and methamphetamine from human plasma and pharmaceutical wastewater, prior to analysis by HPLC.

Selected key technologies of the analytical science industry are discussed by Steve Down with reference to burgeoning application areas and the scope for future improvements.

We are proud to announce a new series of educational webinars run in collaboration with Chromedia, COAST, and SciMind, a product of the American Chemical Society. These webinars will build into a must-have set of tutorial materials for the analytical scientist.

While even the best analytical techniques cannot rectify problems generated by sloppy sample preparation, this less "sexy" step between the point at which analytes are transferred from the sample matrix to a form suitable for analysis is often overlooked. Read a free chapter from "Sample Preparation Techniques in Analytical Chemistry " here.
