Analytical Method: Aluminium (total) in effluents
Photometric determination with Chromazurole S subsequent to acid mineralisation; DIN decomposition
Analytical Method: Chlorophyll-a, -b, -c as per APHA 10200-H
APHA 10200-H describes a measurement against an extraction solution. When the method was zeroed using the stated reagents, no difference in absorbance was found compared with zeroing the method using water for analysis. It is hence possible to use water
Application Notes: Reflectometry – Hydroxymethylfurfural (HMF) in honey
Hydroxymethylfurfural (HMF) in honey – reflectometric determination after after conversion with a barbituric acid derivative and an aminophenazone derivative
