Exploring Dengue Virus Infections with Metabolomics
May 6th 2016Researchers 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).
Identification of Synthetic Colorants Using HPLC–DAD and Chemometrics
May 6th 2016A team of researchers from the State Laboratory of Chemo/Biosensing and Chemometrics in China has developed a novel high performance liquid chromatography-diode array detection (HPLC–DAD) method for the identification of six synthetic colours in five beverages.
Technological Developments in Ion Chromatography
May 6th 2016In 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.
Volumetric Absorptive Microsampling for Hepcidin Peptide Extraction from Whole Blood
May 1st 2016Whole 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.
Challenges & Benefits of Using SFC
April 27th 2016Ted 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.
Development Partners for BioPharma
April 27th 2016Your 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.
Can SBWC Replace HPLC in Pharmaceutical Analysis?
April 25th 2016Subcritical water chromatography (SBWC) is seen as an increasingly enticing prospect to replace high performance liquid chromatography (HPLC) in industrial settings because of its low costs and environmental impact. Yu Yang of East Carolina University, in Greenville, North Carolina, USA, has conducted research into this process for two decades. He recently spoke to Lewis Botcherby of The Column about his work, why companies should consider SBWC, and its role in pharmaceutical analysis.
Investigating Alzheimer’s Using UHPLC–MS
April 25th 2016Researchers from Heilongjiang University of Chinese Medicine, China, have used ultrahigh-performance liquid chromatography coupled to mass spectrometry and metabolomics to investigate the metabolic networks of Alzheimer’s disease, identifying potential biomarkers and biochemical mechanisms.
A Stoichiometric Displacement Model for Proteins in Reversed-Phase LC
April 25th 2016The literature on reversed-phase liquid chromatography (LC) of proteins is reasonably well developed, but not taught in the college classroom much. Kevin Schug therefore wants to focus on a stoichiometric displacement model for reversed-phase LC of proteins and why it is particularly insightful from a practical perspective.
