Nick Ordsmith
Laboratory Scientific Director

Involved in mass spectrometry for over 35 years starting as a Laboratory Technician at Cardiff University followed by 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 this then 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. I am the Study Director for most of our 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 start I have 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. I regularly attend 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.
