应用

Anions in Soil - PT is a solids/soils hazardous waste inorganics proficiency testing material, suitable for testing the concentration of anionic analytes in soil samples.

Our soil PT samples behave as real samples; and, unless there is no alternative, are not simply spikes added to a blank soil. They are designed to meet the requirements of national, regional and state-specific accreditation bodies (TNI, USEPA, UKAS) for quality assurance and continuous improvement.
