The 9th International Symposium on Recent Advances in Food Analysis (RAFA 2019)
September 10th 2019The 9th International Symposium on Recent Advances in Food Analysis (RAFA 2019) will take place in Prague, Czech Republic, on 5–8 November 2019. This preview offers a glimpse of what to expect at the conference.
New LC–MS Detection Method for Short Peptides
September 10th 2019Researchers from the University of Rome have developed a strategy for the identification of underivatized short peptides in urine using graphitized carbon black (GCB) solid-phase extraction (SPE) and liquid chromatography–mass spectrometry (LC–MS).
The LCGC Blog: State of the Art in Microscale-LC Stationary Phase Formats
September 3rd 2019In an effort to better understand the current application potential of microscale liquid chromatography (micro-LC), I picked up a few recent review articles from the literature. What one immediately appreciates from glancing through the literature for such information, is that there are a lot of different configurations and alternative formats, which can be placed under the micro-LC umbrella.
The LCGC Blog: Using Hydrogen Carrier Gas with Mass Spectrometric Detection
August 12th 2019Our recent discussion on the use of hydrogen as a carrier for gas chromatography applications elicited many questions and comments, however one common question was “what are the considerations for using hydrogen carrier with MS detectors?”
Meeting Review: Emerging Separation Technologies 2019
August 6th 2019Organized by The Chromatographic Society and the Separation Science Group of the Royal Society of Chemistry’s (RSC) analytical division, the Emerging Separation Technologies meeting was held on the 28 March 2019 at the RSC’s central London headquarters in Burlington House.
Tips & Tricks GPC/SEC: High Temperature GPC versus Ambient GPC
August 6th 2019Gel permeation chromatography/size-exclusion chromatography (GPC/SEC) is the standard technique to determine the molar mass distribution of synthetic macromolecules. However, some kinds of polymers (for example, polyolefins) are often only soluble in special solvents and require high temperatures to be used during the analysis to keep the sample completely dissolved. Therefore, for the analysis of these polymers, dedicated high temperature GPC systems are used. This article will discuss the pros and cons of both high temperature GPC/SEC and ambient GPC/SEC.
