Sample Preparation @ separationsNOW

The Sample Preparation channel covers all the techniques used to prepare solids, liquids, gases and suspensions for analysis.

Techniques covered include: liquid-liquid extraction (LLE), solid phase (micro)extraction (SPE/SPME), solid-phase and liquid trapping of gases and headspace sampling.

By combining a sample preparation method called turbulence flow chromatography with LC-MS, German scientists have been able to detect three metabolites of a sunscreen ingredient in urine.

In this literature review, chemists from Romania detail the main sample preparation techniques used for large-scale bioanalytical studies with liquid chromatography, including protein precipitation, liquid–liquid extraction, solid-phase extraction and derivatization.

Chemists in Iran coated a nanocomposite film onto a stainless steel fiber for solid-phase microextraction of linear aliphatic aldehydes from rice samples, prior to analysis by gas chromatography.

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.
