The analysis of low concentrations of PO4-P in natural, uncontaminated waters is often challenging. The Spectroquant® photometric test provides an easy-to-use and sensitive method for quantification with results comparable to DIN EN ISO 6878.

Application Note: Peroxidase in vegetables – Visual determination after conversion of a specific substrate.

Protocols

Photometric determination as Iron(III)-thiocyanate

Analytical Method: Iodine in table salt

Photometric determination with Diacetyl monooxime

Hydroxymethylfurfural (HMF) in honey – reflectometric determination after after conversion with a barbituric acid derivative and an aminophenazone derivative
