Reagents for BOD and COD measurement

Water Quality Standards "Reagents for BOD and COD Measurement"

● Reagents for COD Measurement We offer reagents used for measuring Chemical Oxygen Demand (CODMn) by potassium permanganate (KMnO4) as specified by official methods. *Official methods: Industrial water testing methods (JIS K0101) / Factory wastewater testing methods (JIS K0102) / Mine water and wastewater testing methods (JIS M0202) / Sewage testing methods ● Reagents for BOD Measurement Our BOD seed is a blended inoculum that contains bacteria capable of isolating various organic substances, formulated to achieve BOD values equivalent to those obtained from inoculum prepared from sewage sludge. The bacteria included in the formulation are produced and blended under strict product and lot management after being individually cultured. For more details, please refer to the catalog below.

Handling of polystyrene-based particle suspensions for water quality testing "related products for turbidity measurement."

Handling of polystyrene-based particle suspensions for water quality testing "related products for turbidity measurement."

In addition to the conventional kaolin standard solution, we also offer a polystyrene-based particle suspension that is adopted in drinking water quality standards. You can choose according to your purpose.

"Related products for turbidity measurement" are reagents used in testing methods targeting the water quality standard item "turbidity." Traditionally, kaolin standard solutions were used for turbidity measurement; however, due to the increasing precision of measuring devices and the need to address pathogenic microorganisms such as Cryptosporidium, measurements in low turbidity ranges, such as 0.1 NTU, are now required. The water quality standards for drinking water allow for measurements in low turbidity ranges, and polystyrene-based particle suspensions have been adopted as turbidity standard solutions with less variability between batches compared to kaolin. Measurement methods include visual turbidity methods, transmitted light measurement methods, scattered (reflected) light measurement methods, integrating sphere photometric methods, and particle counting methods, which are used for device calibration and as turbidity standard series. 【Product Lineup】 ≫ Polystyrene Turbidity standard solution II for water quality testing (100 NTU) ≫ Formazin Formazin standard solution (400 NTU) ≫ Kaolin Turbidity standard solution for turbidity testing (100 NTU) Turbidity standard solution for turbidity testing (1000 NTU) In addition to these, we offer a variety of standard products for water quality testing. ◇ Pesticide standard solutions ◇ Metal analysis standard solutions …etc. For more details, please download the catalog, refer to our published page, or feel free to contact us.
