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: Hot Pepper Compounds Caught by Cool Coulometric Detection

Whether you love it or loathe it, you may well want to know how much of that hot pepper taste is in the food you buy. Scientists from Brussels, Tokyo and Osaka have developed a novel HPLC method using coulometric detection to quantify capsaicinoids, the compounds that give the hot sensation.

Analysis of Environmental Contaminants in Water Using an Agilent 6470 LC/TQ Instrument

The analytical demands for detecting organic contaminants in water at low ng/L level have pushed the development of new methodologies using LC/TQ instrumentation. In this regard, and in the last few years, advances in sensitivity and selectivity have made this challenge possible. This webinar will focus on the use of the new 6470 LC-MS-MS from Agilent Technologies for the sub ng/L level detection of several pharmaceuticals and pesticides in surface waters. Examples of optimization of several source...

Measurements of the levels of steroid hormones in live whales is crucial to understanding their health and breeding capacity. Researchers from Texas Tech University and the University of Alaska Fairbanks have devised a novel nano-LC-MS/MS method of steroid analysis that requires smaller blubber samples than existing techniques.

Linalyl acetate is found in a number of essential oils, such as those of lavender and bergamot, and in many perfumery products. However, its hydroperoxides have been implicated as sensitising agents. Scientists from the fragrance company Firmenich, based at their Plainsboro New Jersey site, used HPLC combined with chemiluminescence to detect these hydroperoxides.

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.
