The 54th International Symposium on High Performance Liquid Phase Separations and Related Techniques (HPLC 2025) will be held from Sunday through Thursday, June 15-19, 2025, in Bruges, Belgium.
Screening of Pollutants in Water Samples and Extracts from Passive Samplers using LC–MS and GC–MS
August 1st 2012This article describes the GC–MS and LC–MS screening methods developed by the Environment Agency for England and Wales for the analysis of both low-volumn water samples and extracts obtained from various designs of passive samplers.
Analysis of the State of the Art: Liquid Chromatography Instrumentation
August 1st 2012In honor of LCGC's celebration of 30 years covering the latest developments in separation science, we asked a panel of experts (listed in the sidebar) about the current state of the art of high performance liquid chromatography (HPLC) instrumentation and how the technology will develop in the future.
Interactive Liquid Chromatography of Olefin-based Elastomers
July 1st 2012The use of interactive liquid chromatography using porous graphite as a stationary phase and gradients of long chain alcohols and chlorinated aromatics to separate olefin-based elastomers according to their chemical composition is discussed.
"Green" HPLC with 100% Water Eluent for Analysing Melamine in Milk
June 1st 2012A novel "green chromatography" method for analysing melamine in milk is described. The method uses 100% water as the eluent and in the sample preparation stage and is reported to be a reliable and cost-effective method for laboratories in developing countries.
Advances in LC–MS for Food Analysis
May 1st 2012In this review, the most recent LC–MS approaches are discussed, as well as the technical requirements for linking an LC system to a mass spectrometer. The advantages of on-line 2DLC in the "comprehensive" mode are also illustrated and selected applications for the analysis of common foodstuffs, such as triacylglycerols, carotenoids and polyphenols, are described. Finally, future trends for LC–MS in food analysis are reported.
Advances in Multidimensional LC–GC for Food Analysis
May 1st 2012On-line heart-cut LC–GC and, more recently, comprehensive LC–GC (LC?GC) are very powerful analytical techniques because of the combination of the selectivity features of LC with the high efficiency of GC. This article presents an overview of the most recently used interfacing systems, as well as applications in the food analysis.
Synthesis and Applications of BEH Particles in Liquid Chromatography
How ethylene-bridged hybrid inorganic–organic (BEH) particles are prepared and how their special qualities can be used to improve separations
Using MS Data for Peak Tracking in Computer Supported HPLC Method Development
February 1st 2012A systematic way to develop HPLC methods consists of building up and running a useful set of experiments (DOE, design of experiments) to evaluate the influence of several factors or method conditions on the selectivity of a chromatogram. The crucial part here is the peak tracking between the chromatograms.
