In the late “noughties” we couldn’t avoid the webinars, seminars and online calculators which were being released by HPLC column manufacturers to extol the virtues of the “new” core-shell particle morphology that promised high performance at lower back pressures.

Knauer has been ranked as one of the top employers in Germany for 2019, according to a study by 3.works GmbH, a Düsseldorf-based employment research institute.

Virtually exclusively, liquid chromatography–mass spectrometry (LC–MS)-based assays for protein quantitation rely on bottom-up strategies, where the protein is initially digested into constituent peptides during sample preparation. Top-down intact protein quantitation, especially using affordable, low resolution triple quadrupole (QQQ) mass spectrometers, has been largely unexplored.

Solid-phase microextraction (SPME) was introduced nearly 30 years ago and since that time has matured into a widely used tool in the arsenal of sample preparation techniques. Simultaneously, it has spawned a host of related techniques where sorbent coatings are placed on stir bars, magnetic particles, vial walls, and so on. Over the past few years, several advances in SPME have been developed, including increasing the sorbent surface area available for extraction, accommodating direct analysis by mass spectrometry (MS), and sorbent overcoating to resist fouling by sugars, lipids, and other macromolecules present in some sample types. These advances are discussed in this month’s instalment. The use of SPME for microsampling of biological systems, so-called bio-SPME, will be the focus of Part 2.

One millimetre internal diameter liquid chromatography columns are available from many manufacturers. In this article, the utility of 1.0-mm internal diameter (i.d.) columns, and the arenas in which they play a relatively strong role, are investigated. Further, the advantages and disadvantages of 1.0 mm diameter columns are contrasted with both larger- and smaller-bore formats.

In the present study, a novel GC–MS TQ method was developed and validated for the simultaneous analysis of 2-MCPD, 3-MCPD, and glycidyl fatty acid esters in edible oil. This method was subsequently applied to quantitation of these contaminants in commercial edible oil samples.

In this study, we aimed to use a charge modulated HILIC stationary phase (iHILIC®-Fusion) to separate different siderophores of the Pseudomonas taiwanensis VLB120 bacteria.

This application note outlines a simple three-step method for the extraction of loperamide and its main metabolite, N-desmethyl loperamide, from blood. UCT’s Clean Screen® XCEL I column provides users with the same level of sample clean-up as traditional SPE while allowing the elimination of timely conditioning and wash steps.

For your highly sensitive UHPLC–MS analyses, how can you reduce noise and additional signals to a minimum?

The Application Notebook
Antibody-dependent cell-mediated cytotoxicity (ADCC) is a crucial mechanism of action (MoA) of anti-tumour therapeutic antibodies and FcγIIIa receptor plays a key role in this process by interacting with the N-glycans of IgG Fc regions. Hence, affinity chromatography on Fc receptor ligands can deliver valuable information about expected ADCC activity and mAb glycoform distribution.
