Minerals and Inorganics

As important as determining the various organic compounds in your food, feed or dietary supplement product is the determination of significant inorganic components that may have a biological effect. The elements commonly requested for analytical testing have physiological value as nutrients or have detrimental attributes that require monitoring. Certain elements have nutritional benefits at low levels but are toxic at higher levels.

Eurofins Scientific offers a variety of methods for determining the amount of inorganic elements in your products. This enables us to accomodate your testing inorganic testing requirements to best suit your individual needs.

Eurofins Scientific conducts a variety of inorganic analyses. Inductively Coupled Plasma (ICP) and Atomic Absorption Spectroscopy (AAS) methodologies are available.


ICP-OES: INDUCTIVELY COUPLED PLASMA OPTICAL EMISSION SPECTROMETRY

ICP is one of the most commonly used techniques for the determination of dietary minerals. Sample digests are aspirated into a plasma and the elemental emissions are measured on a CCD chip.

This procedure is used for testing food, feed and pet food products for nutrients such as:

AAS: ATOMIC ABSORPTION SPECTROPHOTOMETRY

Like ICP, AAS is a commonly used technique for the determination of low-level elements such as trace metals and micronutrients. It may also be used to determine dietary minerals in some samples due to its greater tolerance for high-solids digests. The sample digest is aspirated into an acetylene/air or acetylene/nitrous oxide flame, and the absorbance is measured at an element specific wave length.
