The benefits of an analytical quality by design (AQbD) approach to method development cannot be underestimated. The Column spoke to Changqin Hu and Xia Zhang from the National Institutes for Food Drug Control, in Beijing, China, about their work developing a dual-gradient elution stability-indicating method for cloxacillin within an AQbD framework.

Mira Petrovic from the Catalan Institute for Water Research (ICRA) in Girona, Spain, reveals the advantages and practical applications of a novel method she developed for the multiresidue trace analysis of pharmaceutical compounds and their corresponding metabolites and transformation products using dual-column liquid chromatography (LC) coupled to tandem mass spectrometry (MS/MS).

The durian fruit is notorious for its unpalatable aroma, and yet the fruit is incredibly popular throughout Southeast Asia and amongst travellers. Holding the title of “the world’s smelliest fruit” attracts attention including that of Martin Steinhaus from the Aroma Research Group at the Deutsche Forschungsanstalt für Lebensmittelchemie (German Research Center for Food Chemistry). He spoke to The Column about his group’s research into the compounds responsible for the fruit’s uniquely unpleasant aroma.

Polyphenols are a well-known group of antioxidants widely diffused as secondary metabolites in plants, vegetables, and fruit. The Column spoke to Nicola Marchetti from the Department of Chemistry and Pharmaceutical Sciences at the University of Ferrara in Ferrara, Italy, about his research into the characterization of polyphenols in red chicory using high performance liquid chromatography–tandem mass spectrometry (HPLC–MS/MS).

The chemical messages that animals use to communicate can trigger a range of responses in members of the same species. The Column spoke to Jorge Saiz from the Centre of Metabolomics and Bioanalysis (CEMBIO) at the University San Pablo CEU, Spain, about his research into the chemical secretions of lizards and the role of gas chromatography–tandem mass spectrometry (GC–MS/MS) in his work.

Monitoring the endocrine status of marine mammals can give valuable information to researchers. Overall health, health issues, and an animal’s pregnancy status can all be deduced from the careful analysis of steroid hormones. However, gaining such data is not easy. The difficulty of obtaining blood samples in the wild necessitates the use of alternative matrices, such as blubber, that in turn provide a number of analytical challenges. Aiming to solve these issues a team of researchers from the National Institute of Standards and Technology (NIST) have developed a novel method using liquid chromatography tandem mass spectrometry (LC–MS/MS) to analyze blubber obtained through remote sample collection. Ashley Boggs from NIST spoke to The Column about the benefits of this newly developed technique and its potential wider application in animal research and management.

There is a growing interest in polyphenols because of their noticeable antioxidant properties and their potential contribution to the defence against oxidative stress and protection against cardiovascular diseases and cancers. Oscar Núñez from the Department of Chemical Engineering and Analytical Chemistry at the University of Barcelona in Barcelona, Spain, has been working since 2010 in the analysis of polyphenols by capillary electrophoresis (CE), liquid chromatography (LC), mass spectrometry (MS), and chemometric techniques to achieve the characterization, classification, and authentication of natural products in the prevention of frauds. He recently spoke to The Column about this research.

Accurate quantification of sugars in saline solution is now possible using a new high performance liquid chromatography (HPLC) method. The Column spoke to Abdelrahman Saleh Zaky from the School of Biosciences at the University of Nottingham (Nottingham, UK) about this method.

Fresh fruit and vegetables have a limited shelf life and so there is a need to ensure that the products reach the shelf in a timely manner and with as little spoilage as possible. Volatile organic compounds (VOCs) are an easily accessible way of monitoring changes in fresh produce. Hilary J. Rogers and Carsten T. Müller from the School of Biosciences at Cardiff University, Cardiff, Wales, UK, investigate these VOCs in fruit and vegetables using gas chromatography–mass spectrometry (GC–MS). They recently spoke to The Column about this research.

Capillary electrophoresis (CE) is routinely used for chemical and biochemical analysis methods, and recently the technique has been implemented on microchips. R. Scott Martin, a professor and chair of chemistry at Saint Louis University, has been investigating ways to improve these techniques for years. He recently spoke to us about his research coupling microchip electrophoresis with electrochemical detection, coupling continuous flow with microchip electrophoresis with valving, coupling microchip CE with microdialysis sampling and electrochemistry, and more.
