应用

Herbicides in Soil - PT is a soil/hazardous waste proficiency testing material, suitable for testing herbicides 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.
