New IANZ Accreditations

Sidebar Image

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.

Aluminium

Antimony

Arsenic

Cadmium

Calcium

Chromium

Copper

Iron

Lead

Magnesium

Manganese

Mercury

Nickel

Potassium

Selenium

Silver

Sodium

Thallium

Tin

Zinc

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In recent years the older style of volatile and non-polar residue compounds have been replaced by more polar, thermo-labile, less volatile, easily degradable compounds.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.
