Merck 114552 Chromate Cell Test (chromium VI and total chromium) 25 tests / EPS box
Catalogue Number
114552
Overview
The method is analogous to APHA 3500-Cr B and DIN 38405-24.
USEPA approved for wastewater.
This Spectroquant® Chromate Cell Test allows the accurate quantification of the chromium(VI) and total chromium concentration in aqueous samples.
Method applied: In weakly phosphoric solution chromium(VI) ions react with diphenylcarbazide to form chromium(III) and diphenylcarbazone which form a red-violet complex that is determined photometrically.
The Spectroquant® Cell Tests come with prefilled 16 mm round cells and all the required reagents to perform the analysis according to the instruction leaflet provided.
All Spectroquant®Cell and Reagent Tests are equipped with the unique Live ID which allows seamless method recognition and contains essential information such as lot number, expiry date, and automatic calibration updates.
