Product introduction
-Highly sensitive measurement of hexavalent chromium at the ppb level in 10 minutes.
-Useful for numerical management of test liquids for various elution tests, such as RoHS-related samples and soil samples.
-This product is a reagent set that uses the color development principle of JIS K 0102 65.2.1 diphenylcarbazide absorptiometry to react with hexavalent chromium dissolved in the test water to form a reddish-purple complex, extract it into emulsion-like hydrophobic ion associates, collect and concentrate on a membrane, and then dissolve and measure it by absorptiometry.
-A total operation takes about 10 minutes, and a concentration rate of 12.5 times (25 mL of test water/2 mL of measurement liquid) is obtained compared to conventional absorptiometry, making it easy to measure hexavalent chromium at the ppb level.
・The water quality environmental standard for hexavalent chromium, the soil leaching amount standard of the Soil Contamination Countermeasures Act (each 0.05 mg/L or less), and the specific groundwater infiltration standard of the Water Pollution Prevention Act (less than 0.04 mg/L) can be determined on-site. It can measure highly sensitively the test liquid of various leaching tests, including electrical and electronic components related to the RoHS Directive.
・This product applies the principle of membrane concentration method using a membrane filter.
