HPLC @ separationsNOW

The HPLC channel covers all techniques used for the separation of liquids.

This includes multidimensional techniques (e.g. LCxLC) and hyphenated techniques (e.g. LC-MS). Also included are capillary LC, nano LC, SEC (Size Exclusion Chromatography) and GPC (Gel Permeation Chromatography).

Last Month's Most Accessed Feature: Metabolites of deadly NPS elucidated by LC-MS

Increasing amounts of new psychoactive substances (NPS), such as butyrfentanyl, are being used across Europe. Researchers from the University of Zurich used a combination of UHPLC and a QTOF (quadrupole time-of-flight) mass spectrometer to detect the metabolites of butyrfentanyl produced in-vitro and in-vivo.

Standard HPLC methods for many pharmaceuticals often use non-volatile salts, such as phosphates, which are incompatible with mass spectrometry. Scientists from Zhejiang University and Zhejiang Institute of Food and Drug Control employed two-dimensional HPLC, with phosphate being used for the first column and formate for the second, to detect novel impurities in the antibiotic cefonicid by mass spectrometry.

Cannabinoid research from an analytical viewpoint is rapidly developing as a more liberal approach to the medical, legal and social issues of the drug is adopted. Start reading our cannabinoid collection of papers here - free to access until the end of December.

Antibiotic residues in meat can be harmful to consumers and lead to increasing populations of antibiotic-resistant bacteria. Scientists from Jaume I University in Castelló, Spain, successfully developed a validated method using micellar liquid chromatography (MLC) to detect antibiotic residues in various types of meat.

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.

Ion source pressure plays a significant role in the process of ionization and the subsequent ion transmission inside a mass spectrometer. Pressurizing the ion source to a gas pressure greater than atmospheric pressure is a relatively new approach that aims to further improve the performance of atmospheric pressure ionization sources. A brief review on the development of super-atmospheric pressure ion sources, including high-pressure electrospray, field desorption and superheated ESI, and the strategies to...

In the current context of international conflicts and localized terrorist actions, there is unfortunately a permanent threat of attacks with unconventional warfare agents. Among these, biological agents such as toxins, microorganisms, and viruses deserve particular attention owing to their ease of production and dissemination. Mass spectrometry-based techniques for the detection and quantification of biological agents have a decisive role to play for countermeasures in a scenario of biological attacks.
