Monitoring water quality relies on the measurement of different parameters, including total suspended solids (TSS) and total dissolved solids (TDS), which are the molecules and ions that remain in a water sample after filtration.
Regulations on workflows and thresholds vary depending on country, region, or city. Regardless of the location, wastewater quality testing is a long, manual process. Proper filtration is vital in this process. Whatman filters 934-AH meet US EPA Laboratory Standard Method 2540 parts C, D, and E and GF/C meet standard for EN872.
