Photometric Analysis with Spectroquant® Instruments & Test Kits

General Description

Method: photometric 0.020 - 1.50 mg/l S²⁻ Spectroquant^®


The method is analogous to EPA 376.2, APHA 4500-S2- D, ISO 10530, and DIN 38405-26.


This Spectroquant^®Sulfide Reagent Test allows the accurate quantification of the sulfide content in aqueous samples.


Method applied: In aqueous solutions of sulfides a pH-dependent equilibrium exists between dissolved hydrogen sulfide (H2S), hydrogen sulfide ions (HS-), and sulfide ions (S2-). In the acidic range practically only dissolved hydrogen sulfide is present which reacts with dimethyl-p-phenylenediamine and iron(III) ions to form methylene blue that is determined photometrically.


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.

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.SPECTROQUANT is a registered trademark of Merck KGaA, Darmstadt, GermanyGHS05H290 - H314P234 - P280 - P303 + P361 + P353 - P304 + P340 + P310 - P305 + P351 + P338 - P363
