Basics
All organic materials, i.e. pertaining to raw vegetable and animal material, can be tested for their geographical origin by means of isotope analyses. This provides a product retraceability independent of any accompanying documentation.
Whether the aspargus originally came from Germany or Greece, the steak from Argentina or England or the wood out of Scandinavia or Russia can be determined at Agroisolab GmbH, simply by testing a small product sample.
The basis is a comparison of the isotope value of a well-known geographical location with the isotope value of the sample to be tested for its origin. Hence the method requires the availability of authentic isotope reference material or corresponding database information. Depending on the test objectives there are different requirements for the kind and quantity of the reference samples.
We inform you gladly in detail.
A comparison of isotope values can only be carried out between samples from the same kind of product because each biological species has an own characteristic metabolism. The saying "one cannot compare apples and oranges" can be taken literally here.
The principle of operation of the isotope analysis will be explained in detail under the menu entry "Isotope Analytics".
