In 2009 I wrote an article on the emerging field “Bio Chromatography,” which for a small molecule analyst such as myself, perfectly described the situation. I realize that the separation of biomolecules had been happening for many years, but the expansion and development of protein based therapeutics from that point onwards has seen an avalanche of developments in instrumentation, sample preparation, and column technologies the like of which I have not seen in my 30 year career.

The recent introduction of high resolution, accurate mass (HRAM) OrbitrapTM technology coupled to GC brings a new level of performance and flexibility in full scan acquisition and more. Comparable sensitivity and selectivity of triple quadrupole GC-MS/MS, but with broad scope, and the capability for simultaneous targeted and non-targeted analysis of pesticides at low ng/g concentrations, in complex sample types. In this Q & A, Paul Silcock discusses the story so far, around the use of Orbitrap GC-MS for quantitative and qualitative multi-residue analysis of pesticides.

Gas chromatography (GC) is a powerful technique for environmental analysis. The articles in this new e-book look at both the technique and its application, providing essential information about GC fundamentals as well as an example of how the technique can be used in new ways in environmental analysis.

Researchers from Colorado State University have demonstrated the viability of exploratory metabolomics and HILIC–MS in identifying biomarkers associated with dengue virus (DENV) infections, such as dengue fever, dengue haemorrhagic fever/dengue shock syndrome (DHF/DSS).

In this Q&A, we will talk to Dr. Arthur Fitchett, Director of Sales Training at Thermo Fisher Scientific. We will discuss recent advances in ion chromatography technology, what they mean for different types of IC analyses, and how they can improve results in your laboratory.

Whole blood analysis is an emerging trend in the field of bioanalysis. We developed a fast and simple protocol to extract and analyze a peptide, hepcidin, from whole blood. Sampling and extraction were carried out using volumetric absorptive microsampling (VAMS), a novel blood collection device that allows the sampling of a known blood volume independently from hematocrit. The composition of the extraction medium was optimized using an experimental design to get the most intense signal of hepcidin, considering different organic solvents and acidic additives.

Ted Szczerba, Technical Director of Chromatography and SFC Separations at Regis Technologies, overviews incorporating Supercritical Fluid Chromatography (SFC) into his separations lab. With over 30 years experience working with chiral compounds and over 10 years running SFC, he assesses the value of the technique versus the drawbacks of what is available in the field today. Learn about a typical screening day and this industry veteran's advice on what is needed for an effective separations process.

Your current contract laboratory and instrument provider may be familiar and comfortable, but, maintaining the status quo doesn’t lead to greater rewards. In fact, it often involves putting up with less-than-desired results. Join us in this executive summary to hear how Ajinomoto Althea develops unsurpassed solutions for biopharma companies, and how a team at Thermo Fisher Scientific has challenged the status quo to deliver uncompromised UHPLC.
