Method: photometric 10 - 300 mg/l Na Spectroquant®

This Spectroquant® Sodium Cell Test is especially designed for the analysis of nutrient solutions for fertilization. It allows the accurate quantification of the sodium content in such samples via the determination of associated chloride ion concentrations.

Method applied: The chloride ions equivalent to the sodium ions react with mercury(II) thiocyanate to form slightly dissociated mercury(II) chloride.

The thiocyanate released in the process in turn reacts with iron(III) ions to form red iron(III) thiocyanate that is determined photometrically.

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.
