General description

Method: photometric 1.0 - 60.0 mg/l SO₃²⁻ 0.8 - 48.0 mg/l SO₂ Spectroquant^® This Spectroquant^® Sulfite Reagent Test allows the accurate quantification of the sulfite content in aqueous samples as well as in food and beverages (e.g. beer).Method applied: In neutral solution, sulfite ions react with 2,2’-dinitro-5,5’-dithiodibenzoic acid (Ellman’s reagent) to form an organic thiosulfate. This reaction results in the release of a thiol which 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.
