Popis

General description

(free and total chlorine) Method: Photometric, 0.010 - 6.00 mg/L (Cl2), Spectroquant^®

This Spectroquant^® Chlorine test allows the accurate quantification. Chlorinated disinfectants are still in common use all over the world, their major applications being in the chlorination of drinking water and swimming pools. In weakly acidic solution free chlorine reacts with dipropyl-p-phenylenediamine (DPD) to form a red-violet dye that is determined photometrically. In the presence of potassium iodide, also combined chlorine is measured in this reaction.
The method is analogous to EPA 330.5, APHA 4500-Cl2 G, and DIN EN ISO 7393-2.
All our Cell and Reagent Test Kits are equipped with the unique Live ID (2D barcode) which allows seamless method recognition and contains essential information such as lot number, expiry date, and automatic calibration updates.
The Spectroquant^® Reagent Test Kits contain highly stable, ready-to-use reagent mixtures to perform the analysis according to the procedure described in the accompanying instruction leaflet.

Application

• 3,3′,5,5′-tetramethylbenzidine as multi-colorimetric indicator of chlorine in water in line with health guideline values.: This study demonstrates the use of 3,3′,5,5′-tetramethylbenzidine as a colorimetric indicator for detecting chlorine levels in water, providing a cost-effective and simple method for ensuring water safety in compliance with health guidelines (Palladino et al., 2020).
• Analysis of free chlorine in aqueous solution at very low concentration with lateral flow tests.: Investigates the effectiveness of lateral flow assays for the quantification of free chlorine in water, highlighting their potential for quick and accurate chlorine testing in field settings (Schwenke et al., 2019).
• Improved residual chlorine test; the ortho-toluidine: arsenite method for testing water for true, false and chloramine residuals.: Describes a methodological advancement in measuring different forms of chlorine residuals in water, enhancing the accuracy of water quality assessments (GILCREAS FW, 1948).
