New IANZ Accreditations
During November Eurofins-ELS achieved two significant IANZ milestones by gaining accreditation to test metals in a wide range of food matrices using ICPMS, and also acid herbicide compounds in using LC-MS/MS.
Metals in Food
This new accreditation covers 11 diverse food scopes such as Cereals, Edible oils, Nuts, Sauces, Sugars and confectionery, Dairy products, Meats, Fish, and Eggs as well as alcoholic and non-alcoholic beverages.
These products will be digested by the lab using in-house techniques and will be analysed for any of the following elements.

Acid Herbicides
In recent years the older style of volatile and non-polar residue compounds have been replaced by more polar, thermo-labile, less volatile, easily degradable compounds. Acid herbicides fall into this class and are found in wide use around the world because of their relative cheapness and effectiveness as broad-leaf weed killers in grain crops.
Acid herbicides readily dissolve in water due to their polarity having half-lives in soil and water ranging from weeks to months depending on the prevailing environmental conditions such as pH and light intensity.
Testing for these compounds is a requirement under many resource consents, for drinking water compliance and for compliance with Ministry for Primary Industries export requirements. Eurofins can test your samples in these matrices as well as soil and sludge.
