Microwave Digestion of bio-hemp face cream

A sample preparation method to determine trace elements in bio-hemp face cream is introduced below. The face cream contains hempseed oil, vitamin E, glycerin, propane-1,2-diol and various other ingredients. The samples are digested using speedwave XPERT in high pressure DAK-100 vessels. During the digestion, the reaction temperature and pressure are controlled via contactless in-situ temperature sensor (DIRC) and pressure sensor (OPC) to ensure efficient digestion.
