Previously, he held roles at Organon leading their separation sciences team in Newhouse, Scotland; Applied Biosystems as a mass spectrometry applications specialist; and as a bioanalytical mass spectrometrist at Covance.
Tim’s expertise lies in separation science, quantitative mass spectrometry, and pharmaceutical analysis. He values continuous improvement, lean leadership, and sound strategy development.
Tim has a BSc (Hons) in chemical and pharmaceutical sciences from the University of Sunderland. He is a member of the Royal Society of Chemistry and the Research Quality Association.
Laboratory Scientific Director
Nick’s 35-year involvement in mass spectrometry started as a laboratory technician at Cardiff University. He then moved on to work as mass spectrometer analyst at Inveresk Research in Scotland, applications laboratory manager at VG Analytical/Waters in Manchester, before joining Hall Analytical in 1998. Initially tasked with generating the validation data to support Hall Analyticals UKAS accreditation for environmental testing, his role developed into overseeing GLP accreditation for our E&L and pharma studies. Working on quantitative studies of pharmaceutical impurities and validations of the methods led to similar studies in the agrochemical industry. Additionally, he is study director for most of Hall’s agrochemical GLP 5 batch studies and, through relationships developed with scientific groups in China, established a partnership with BioReg who operate as our representatives there. Involved with our polyurethane foam testing from the beginning, he has also worked closely with the European and US trade associations to secure “approved laboratory” status to support the CertiPUR and CertiPUR -US quality labels for slabstock foam. He regularly attends the annual meetings of Europur and the US Polyurethane foam association to provide technical support and present analytical updates to both groups and their members.
Nick has a BSc (Hons) environmental science with chemistry and an MSc in organic and analytical chemistry.
Laboratory Operations Manager
Kythe has been at Hall Analytical for over 19 years with experience in many aspects of the company. Trained in LC-MS under the guidance of Dai Games at UWIST, he enjoys a role at the cutting edge of LC-MS development. This experience has been applied to a number of applications at Hall, in particular extractables and leachables testing.
Kythe has a BSc chemistry (Hons).
Dr Andrew Feilden
European E&L Strategic Director
Andrew garnered over 20 years of experience supporting the pharmaceutical industry before joining Hall Analytical in November 2019. Prior to Hall, he was at Smithers as chemistry operations director. He worked for AstraZeneca for 12 years, leading extractable and leachable testing, working on a variety of dosage forms. He also has authored regulatory documents for drug substance and CCS (IMPD and NDA) resulting in successful regulatory approval. He has presented in over 15 countries worldwide on the subject of E&L.
Andrew has a BSc Chemistry (Hons) and a DPhil from the University of York. He is a Chartered Scientist and has been a scientific advisor to IPAC-RS and co-chair of ELSIE group.
