General description

(o-phosphate) Method: photometric, PMB 3.0 - 100.0 mg/l PO₄-P 9 - 307 mg/l PO₄³⁻ 7 - 229 mg/l P₂O₅ Spectroquant®
This Spectroquant® Phosphate Cell Test allows the accurate quantification of the orthophosphate content in aqueous samples.
In sulfuric solution orthophosphate ions react with molybdate ions to form molybdophosphoric acid. Ascorbic acid reduces this to phosphomolybdenum blue (PMB) that is determined photometrically.
The method is analogous to EPA 365.2+3, APHA 4500-P E, and DIN EN ISO 6878.
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 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.
