Solutions for Proficiency Testing (PT)

Feb 27 2018 Read 131 Times

With over 20 years of experience in proficiency testing (PT), Merck offers proven products and services to help you demonstrate your lab’s expertise. Our PT studies cover all major environmental parameters in organic compounds, metals, wet chemistry, and microorganisms.

For each study, you will receive a high-quality PT sample, produced at our ISO/IEC 17025 and ISO/IEC 17043 double accredited facility in Laramie, Wyoming (USA).

Choose from a broad range of US EPA/global PT schemes for:

• WS (Water Supply/Drinking Water)

• WP (Water Pollution/Waste Water)

• LPTP (Solids/Soils/Hazardous Waste)

• AIR (Air)

• MIC (Microbiology)

We also offer several country-specific PTs (DMRQA/WETT). We also offer Quick-turn studies, these are similar to scheduled PT schemes, however they are available on demand whenever you need them. Laboratory QA departments use these for corrective action, to train new personnel, to validate new methods, or as blind samples for demonstrating analytical competence.
