Pesticide Proficiency Testing (PT)

ISO 17025 accredited laboratories are required to take part in proficiency testing (PT ) programs to demonstrate performance and method validation. Sigma-Aldrich RTC is ISO 17043 accredited (general requirements for the competence of providers of proficiency testing schemes) and has many years of experience in developing and producing natural matrix samples for use as PT samples.

RTCs environmental PT programs cover pesticides in drinking water, waste water and soils. Laboratories can choose to participate in our quarterly or semi-annual PT programs, or simply purchase PT samples. Find information about PT registration and schedule at sigma-aldrich.com/pt or order the “ RTC environmental proficiency testing” brochure.
