General description

Taste - Drinking Water proficiency testing material is produced in accordance with ISO/IEC 17043:2010. This product is also referred to as Potable water or Water Supply sample. The PT portfolio allows our test components to offer significant performance data to monitor and prove competency to customers, accreditation bodies or both.

Supelco® is a global proficiency testing (PT) provider that manufactures best-in-class environmental and pharmaceutical PT products. Most water PT samples are available as concentrates or ready-to-use volumes giving the end-user flexibility in selecting samples that will fit their exact needs. Our WS program is designed to meet the quality assurance requirements in compliance with the Safe Drinking Water Act (SDWA), thereby ensuring the analytical competence of your laboratory or drinking water facility.

Our product simulates drinking water contaminated with chemicals that produce taste and odor defects, thereby challenging a laboratory′s ability to identify the unknown chemical capable of causing ‘off′ taste or odor.
