Microwave Digestion of herbal medicine

A sample preparation method to determine trace elements in herbal sleeping medicine is introduced below. Herbal tablets containing dry extract of valerian roots, silicon oxide, titanium oxide, calcium carbonate, magnesium stearate and various other ingredients are digested using speedwave XPERT in DAK-100 vessels. During the digestion, the reaction temperature is controlled via contactless in-situ temperature sensor (DIRC) to ensure efficient digestion.
