Filtration Products for use with TSS Analysis Total Suspended Solids Analysis applications that follow the US EPA Laboratory Standard Method 2540 parts C, D, and E, require pretreatment of the filter paper being used. This pretreatment process includes pre-washing, drying, cooling, and desiccating and weighing the filter paper. These steps can be a hassle for laboratories that don’t possess the proper equipment and can also bring down laboratory efficiencies. Tisch Scientific sells two filter paper products recommended for TSS analysis that come already pre-treated and ready to use, which will eliminate the need for the user to perform these steps themselves. 934-AH RTU Filter Paper 934-AH has a particle retention rating of 1.5um with optimal flow rates designed especially for TSS analysis. The high loading capacity gives these filters the ability to handle very thick, particulate laden samples. Common applications include: Analysis of rivers, lakes, coastal water, discharge from industrial plants, and the purification of discharge from wastewater treatment plants. The 934AH RTU is pre-treated and packaged in an aluminum pan with the filter weight clearly labeled on a heat resistant label.
