Protocols

Analytical Method: Chlorophyll-a and phaeophytin-a as per DIN 38412 / ISO 10260

Method: Spectrophotometric, method for surface water

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 for analysis to zero the method.

Analytical Method: Determination of Sugar Solution Color at pH 7.0 by the MOPS Buffer Method (According to ICUMSA Method GS9/1/2/3-8)

Method: Spectrophotometric Color Determination at 420 nm

Analytical Method: Determination of the Solution Color of Raw Sugars, Brown Sugars and Colored Syrups at pH 7.0 (According to ICUMSA Method GS1/3-7)

Method: Spectrophotometric Color Determination at 420 nm Zero adjustment For each measurement series, a zero adjustment is required. It is recommended to use the same cell for zero adjustment and for sample measurement. The zeroing procedure for the measurement series is automatically prompted by the instrument after entering the %RDS value.
