The Challenges of Climate Change for Wine Production
September 10th 2019Heatwaves are significantly affecting the consistency and quality of wine production. The Column spoke to Julia C. Gouot from the National Wine and Grape Industry Centre in Australia about the importance of chromatography to understand the effects of temperature change on grape physiology and composition.
New LC–MS Detection Method for Short Peptides
September 10th 2019Researchers from the University of Rome have developed a strategy for the identification of underivatized short peptides in urine using graphitized carbon black (GCB) solid-phase extraction (SPE) and liquid chromatography–mass spectrometry (LC–MS).
Sourcing Prebiotic Oligosaccharides from Vine Shoots
May 8th 2019Following decades of research, evidence of the human microbiome’s importance in maintaining overall health and well-being has become evident, spawning a multimillion-dollar industry. A wide range of products aimed at repairing and maintaining a healthy microbiome are now available, with many focusing on prebiotics.
The Role of Chromatography in Entomotoxicology
April 9th 2019The detection of drugs or other toxic substances can be crucial to forensic investigations. However, if the investigation involves a heavily decomposed, skeletonized, or missing corpse, that information can be difficult to obtain, and may require the skills of a unique branch of forensic toxicology-entomotoxicology. To explain the role of chromatography in this field, The Column spoke to Paola A. Magni from Murdoch University, in Perth, Australia.
Investigating Mycobacteria FAME Profiles Using Alternative Ionization Energies in GC–MS
April 9th 2019Highly repeatable fragmentation of the compounds into the ion source is one of the major advantages of using gas chromatography coupled with electron ionization mass spectrometry (GC–EI-MS) for the analysis of volatile and semivolatile compounds. The generation of intense and diagnostic fragmentation when the ionization is performed at 70 eV has been used for the creation of many established databases-enabling the analyte identification process.
House of Lords Calls on UK Government to Secure Science Funding
April 9th 2019The House of Lords EU Home Affairs Sub‑Committee has highlighted the risk of losing access to key sources of Horizon 2020 funding in a “no-deal” scenario and called on the Government to confirm that the UK will seek full association to the next phase of the programme, “Horizon Europe”.
