Suspended solid (SS) is a particulate matter less than 2 mm in water and an important indicator of Environmental Water Quality. SS was traditionally analysed by weighing in laboratory. Recently, automatic continuous measurement of SS was included as a routine monitoring of Water Tele-Monitoring System (TMS) in Korea by “Law for Environmental Testing and Inspection” and by “Law for Water Quality and Aquatic Ecosystem Preservation.” However, the standard material for this automated SS analysis is not well defined in the Korean official method. The research used microcrystalline cellulose which is the standard material of ISO 11923 as a reference material and used cellulose fiber medium and Inulin as comparative materials which have same molecular formula with microcrystalline cellulose. Recovery rates of microcrystalline cellulose, cellulose fiber medium, and Inulin were 100.1%, 100.5%, and 30.9%, respectively. Some part of Inulin was dissolved in distilled water, so it cannot be used for the standard material. The variation coefficients of microcrystalline cellulose, cellulose fiber, and inulin were 5.5%, 7.7%, and 6.0%, respectively. The correlations between laboratory SS and TMS results for all materials were very high (r > 0.99). It seems like that microcrystalline cellulose suggested by ISO can be the best standard material for TMS within the conditions tested in this research.
