VOHs and benzene derivatives in waste waters at low concentration levels

image banniére

Description of the programme

This interlaboratory comparison (AGLAE's programme ‘4Eb’) in waste waters similar to industrial waste waters is provided in the frame of:

  • accreditation scopes related to physico-chemical analyses in waters (check AGLAE's accreditation - Cofrac No. 1-1664)

  • approvals issued by Departments of environment

This proficiency testing is identical to the test 'VOHs and benzene derviratives in waste waters’ but at lower concentration levels to meet specific requirements.
