About PROOF-ACS

PROOF offers high-quality, up-to-date competence schemes, tailored to customers’ needs. We always go the extra mile for providing reliable services: Careful selection of test parameters, concentration levels and choice of matrix are core to the design of PROOF competence schemes. The scientifically based evaluations go far beyond a sole statistical evaluation.

PROOF-ACS was founded in 2012 as a spin-off of „Lach & Bruns Partnerschaft“.
