The development of a microfabricated comprehensive GC that can be used as a portable measurement device.
In this extended special feature to celebrate the 30th anniversary edition of LCGC Europe, leading figures from the separation science community explore contemporary trends in separation science and identify possible future developments. We asked key opinion leaders in the field to discuss the current state of the art in liquid chromatography column technology, gas chromatography, sample preparation, and liquid chromatography instruments. They also describe the latest practical developments in supercritical fluid chromatography, 3D printing, capillary electrophoresis, data handling, comprehensive two‑dimensional liquid chromatography, and multidimensional gas chromatography.

When the unique shape-selective properties of PGC are appropriately identified, PGC stationary phases can be harnessed for fine separations of structurally related compounds.
A hybrid HILIC–ion exchange column was used for the analysis of ultrashort-chain per- and polyfluoroalkyl substances (PFAS) compounds in environmental waters. This direct injection LC–MS method enables simultaneous measurement of ultrashort- chain, alternative, and legacy PFAS in potable and non-potable waters.
This automated SPE methodology is a solution that will reduce analyst labor, solvent usage, and turn-around-time while maintaining the high quality results required within today's laboratories.

A newly developed high-throughput method for the quantitation of vitamin D using both multiplexed LC and on-line SPE is discussed.
The authors characterized 12 SFC achiral stationary phases with 60 compounds from four chemical classes to establish guidelines for th rational selection of the optimum stationary phase for separations.
The different aspects of food metabolomics are described using tomato taste as an example.
A look at the role of system suitability tests (SSTs) during performance qualification (PQ).
Recent advances in stationary phases for hydrophobic interaction chromatography (HIC) permit HIC–MS analysis of intact antibodies and other proteins using direct flow to the mass spectrometer.
Metabolomics, the study of small molecule metabolites that are found within a biological sample, is an emerging field of study. Progress in this field depends upon technological advancement in the fields of LC–MS and separation technology.

The inclusion of time-resolved selected reaction monitoring (SRM) functionalities into mass spectrometer control software allows large numbers of peptides to be quantified using short LC–MS-MS methods.
Detection, analysis, and characterization of low-abundant metabolites remain an unresolved problem in metabolic studies. In this study, we report a novel approach to address this challenge. The current methodology is derived from the predictive multiple reaction monitoring (pMRM) mode available on triple-quadrupole linear ion trap mass spectrometry (MS) systems. The pMRM mode offers the highest sensitivity among various acquisition modes for studying trace levels of metabolites of the herbicide clomazone in plants. Additionally, this method allows for the identification of positional isomers of metabolites.
In this LCGC Blog, the author explores stationary phases that incorporate permanent or induced charges within, or alongside, hydrophobic alkyl silica type bonded ligands.

This study presents results of gel permeation chromatography (GPC) and analytical temperature rising elution fractionation (TREF) of polyethylene in butylal (dibutoxymethane, a halogen-free solvent).
Antibody related biopharmaceuticals represent one of the most dynamic segments of the pharmaceutical market. The analysis and monitoring of product titers in CHO cell cultures is one of the key tasks during development of new products. Cell line selection, optimization of expression rates, and process control need fast and efficient antibody quantification. Besides ELISA assays with known limitations with regard to reproducibility and precision, high performance liquid chromatography (HPLC) analysis using affinity chromatography is applied. This application note summarizes some performance data of a new Protein A affinity column for mAb titer analysis.
