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.

Chinese scientists have used headspace solid-phase micro-extraction to sample the volatile compounds released by five different pathogenic bacteria for subsequent analysis by gas chromatography-mass spectrometry.

Using ionic liquid and cellulose, Chinese scientists have developed a method for extracting phenolic compounds from bee propolis that is faster, greener and more effective than previous methods.

Researchers from Iran and Norway have combined electromembrane extraction with dispersive liquid–liquid microextraction to extract the antimicrobial compound thymol from the herb Carum copticum.

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.
