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

Analytical Method: Analytical Quality Assurance, Standard for Formaldehyde

Preparation of a standard solution for Formaldehyde

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

Analytical Method: Sulfate in Building Materials

Photometric or turbidimetric determination subsequent to water extraction/fusion melting
