Polymer Char are holding a “User Training Meeting” at the 6th International Conference on Polyolefin Characterization (ICPC), Shanghai, China, 6–9 November 2016.

Researchers from the China Pharmaceutical University in Nanjing, China, have published a review of the recent advances in the preparation and application of monolithic capillary columns in separation science.

A publication in TrAC Trends in Analytical Chemistry has covered the recent advances in microfluidic liquid chromatography.

Victor U. Weiss and Günter Allmaier from TU Vien discuss how combining molecular beacons with chip capillary electrophoresis (CE) offers scope to investigate viral RNA replication and improve gene therapy delivery systems.

Doping and cheating the competition may be as old as competition itself. Doping horses for chariot racing was reported during the Roman Empire and doping is now commonly reported in the press. Advanced technologies such as ultrahigh-pressure liquid chromatography (UHPLC) analysis coupled to ultrafast tandem mass spectrometry (MS/MS) detection provide excellent sensitivity for the analysis of horse doping agents.

How to optimize the key variables in HPLC analysis-sample preparation and column selection

Systematic toxicological analysis (STA) is an important step in medicolegal investigations of death, poisoning, and drug use. The primary goal is the detection and confirmation of potentially toxic compounds in evidence. This article describes a workflow using non-targeted liquid chromatography–tandem mass spectrometry (LC–MS/MS) for reliable compound identification. Tandem mass spectrometry was performed on a low-resolution quadrupole-quadrupole-linear ion trap instrument. Acquired spectra were submitted to automated library search, and positive matches were verified by expert reviewing. After validation, the non-targeted LC–MS/MS technique was integrated in the STA service provided by our laboratory.

Detectors based on ultraviolet absorbance are the most common detectors in use for liquid chromatography.

The past couple instalments of “Sample Preparation Perspectives” have looked at current trends in the field. Another recent trend is dried blood spot analysis and other analysis methods using minute sample amounts. This month we take a quick look at the role of sample homogeneity and the determination of sample size. Microsampling approaches, including dried blood spots, are discussed.

As Klaus Unger turns 80, we review his contributions to the field.

The future of biological and clinical research will depend on technological innovations and cross discipline cooperation as science seeks a deeper understanding of increasingly complex biological systems. The 2016 recipient of the AES Mid-Career Award, Amy Herr, and her team at the University of California Berkeley have explored these areas using a combination of chemical engineering, mechanical engineering, and electrical engineering with strong foundations in biology, material science, and analytical chemistry to innovate new microfluidic analytical technology. She recently spoke to LCGC about this work.
