Proof-ACS

Who we are

PROOF-ACS GmbH is an independent company, solely financed by organisation of competence schemes and the distribution of reference materials. Four shareholders only allow flat hierarchies and a fast decision-making process.

Therefore, PROOF is able to assess analytical results in an independent way – detached from any external parties.

Shareholders are:

  • Dr. Silke Bruns
  • Dr. Günter Lach
  • Dr. Birgit Schindler
  • Dr. Ralph-Matthias Schoth

Dr. Silke Bruns, Dr. Günter Lach and Dr. Ralph-Matthias Schoth are acting as consultants and support the business development of PROOF-ACS.
