Elemental analysis investigates the elementary composition of foodstuffs. In this process, both naturally occurring elements (bulk and trace elements) and elements that are added can be determined.
Information on the contents of bulk and trace elements in foodstuffs are of particular interest for the consumer. Therefore, the legislature regulates the information related to nutritional values and health-related information (health claims) on the labels. In Switzerland, the Ordinance on the Labelling and Advertising of Foodstuffs (Lebensmittelkennzeichnungsverordnung, LKV) applies here.
Additionally, numerous inorganic environmental contaminants such as the heavy metals arsenic, lead, mercury and cadmium can be identified by using element spectroscopy.
In our modern laboratory, spectroscopic measurement techniques such as atomic absorption (AAS), emission spectroscopy (ICP-OES) or the highly-sensitive coupling of ICP with a mass spectrometer (ICP-MS) are available.
Depending on the question being asked, element screening can be carried out along with the targeted detection of an individual element. Here, up to 23 elements can be identified in one analysis process.
Do you have any question on the interpretation of the Food Labelling Ordinance (LKV) or do you require help in the evaluation of the test results? Then take advantage of our experience from more than 45 years of foodstuff analysis.
