Merck, 1.02537.0001, Sulfate Test

Method: photometric 5 - 300 mg/l SO₄²⁻ Spectroquant® The method is analogous to EPA 375.4, APHA 4500-SO42- E, and ASTM D516-11. This Spectroquant® Sulfate Reagent Test allows the accurate quantification of the sulfate content in aqueous samples. Method applied: Sulfate ions react with barium ions to form slightly soluble barium sulfate. The resulting turbidity is measured in the photometer (turbidimetric method). 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.
