InProcess-LSP was founded in 2014 at the Pivot Park in Oss, The Netherlands. We are an innovative scale-up company, which is formed by a group of scientists with a strong background in Process Analytical Technology, pharma and life science industry. InProcess-LSP developed a unique and true PAT instrument for inline and online nanoparticle analysis by combining spatially resolved optical technology with Dynamic Light Scattering.

Our goal is to further explore the full potential of the spatially resolved light scattering technology to provide meaningful and innovative PAT solutions. In total InProcess-LSP has now 8 people employed, which is increasing rapidly

Ad Gerich

Co-founder and Managing Director of InProcess-LSP

July 2014-Present

Managing InProcess-LSP & business development. PAT application development & projects, instrument development and consultancy for mainly pharma related companies. Ad has an academic background in chemistry and chemometrics and worked as a scientist between 1990 and 2002 for animal feed and pharma companies (Organon). In 2002 he became a group leader of Pharmaceutical Analysis within the Product Development department Organon. After different positions as PAT project leader and PAT group leader and organizational changes Ad ended his career in pharma industry in 2014 as Director Product Development within Merck. PAT, QbD and six-sigma are typical areas of expertise.
