Mark Powell Scientific Limited

Mark Powell is a Fellow of the Royal Society of Chemistry (RSC) with over twenty-five years’ experience as an analytical chemist. He is an expert in sampling and sample preparation, chromatography (liquid and gas), spectroscopy (atomic and molecular) and pharmaceutical dissolution testing.  Mark was Honorary Treasurer of the RSC’s Analytical Division and led a working group on continuing professional development until July 2016.

After completing a PhD in analytical chemistry, he worked at a senior level in a number of industrial laboratories. Mark joined Liverpool John Moores University’s School of Pharmacy and Chemistry in 1997 as a Senior Lecturer, teaching chromatography, mass spectrometry and sample preparation.  He was Programme Leader for the University’s MSc in Instrumental Chemical Analysis and was also active in research and consultancy.

In 2003, he joined the newly-formed Quay Pharmaceuticals, a contract research and manufacturing organisation specialising in early-stage drug development, where he set up the analytical facility and managed the analytical development programme. In 2010 Mark was appointed Quay’s Scientific Manager, becoming involved more generally with drug development programmes and establishing collaborations with a number of UK universities and instrument manufacturers. Mark left Quay Pharmaceuticals in September 2013 to set up Mark Powell Scientific and has enjoyed working with companies of all sizes around the world on a variety of training, consultancy and expert witness assignments.
