Protocols

Determination of Calcium in Beer

Using the Spectroquant® photometric system, we outline a photometric analysis of calcium levels in beer.

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.

Analytical Method: Nitrite in potato instant powder

Photometric determination using the Griess method subsequent to extraction

Analytical Method: Aluminium (total) in effluents

Photometric determination with Chromazurole S subsequent to acid mineralisation; DIN decomposition
