B-590.67.191 [2022-09] Potassium (K) – AAS

The elements found in the human body are, according to their respective concentrations, divided into minerals and trace elements. These comprise elements, such as potassium, calcium, sodium, magnesium, iron, copper, zinc and manganese, which are already present in dissolved (ionized) form in wort or beer. The positively charged particles are known as cations.

Application/Purpose

Determination of the potassium content by means of AAS

Scope of Application

Suitable for all types of wort, beer and beer-based beverages

Principle

The potassium in beer is determined using atomic absorption spectroscopy (AAS) by directly aspirating the diluted sample into an acetylene oxygen flame. The measurement occurs at 766.5 nm. A cesium chloride addition reduces interference from the ionization of compounds in the beer matrix.
