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.
