Selvarani Elahi has taken over the role of deputy government chemist, becoming the first female scientist to hold this title in the UK. She will now act as deputy for Dr Derek Craston, who has been the UK’s government chemist since 1 June 2008. In addition to her new role, Elahi retains her current position as head of consumer protection services at LGC.
Speaking about her appointment, Selvarani Elahi said: "I am extremely pleased to be taking up the post of deputy government chemist and I look forward to supporting Dr Derek Craston in his role as the UK’s government chemist. The government Chemist function is fundamental to providing an independent voice for sound analytical measurement science and preventing miscarriages of justice. As well as resolving disputes, a key aspect of the role is preventing disputes from arising by conducting salient project work and giving well informed advice to stakeholders. My experience of the analysis of food and animal feed will help me to discharge my duties in this important statutory role.”
The government chemist title has been in place since 1911, to resolve disputes over analytical measurements, particularly in relation to food regulatory enforcement. The government chemist also takes an active involvement in promoting analytical science and technology, and provides advice to government and the wider community on policy, standards and regulation.
The Complexity of Oligonucleotide Separations
January 9th 2025Peter Pellegrinelli, Applications Specialist at Advanced Materials Technology (AMT) explains the complexity of oligonucleotide separations due to the unique chemical properties of these molecules. Issues such as varying length, sequence complexity, and hydrophilic-hydrophobic characteristics make efficient separations difficult. Separation scientists are addressing these challenges by modifying mobile phase compositions, using varying ion-pairing reagents, and exploring alternative separation modes like HILIC and ion-exchange chromatography. Due to these complexities, AMT has introduced the HALO® OLIGO column, which offers high-resolution, fast separations through its innovative Fused-Core® technology and high pH stability. Alongside explaining the new column, Peter looks to the future of these separations and what is next to come.
Metabolomics Analysis of Low Birth-Weight Infants Using UHPLC-MS/MS Following Lipid Emulsion
January 10th 2025A recent study aimed to directly compare the changes in serum metabolites among very low birth-rate (VLBW) infants following the administration of the soybean oil-based lipid emulsion and soybean oil, medium-chain triglycerides, olive oil, and fish oil (SMOF) lipid emulsion using untargeted metabolomics techniques.
