Price of the test:

$50 per analysis

Acceptable Matrices:

Foodstuffs, Food Ingredients, Nutraceuticals, Beverages

Unacceptable Matrices:

Some classes of compounds are unsuitable for closed vessel microwave digestion because they are highly reactive with nitric acid and other oxidizers which may become nitrated and potentially explosive.   These matrices include: animal fat (lard), glycerin and glycols, volatile flavoring agents, and alcoholic beverages. If you have a question as to whether your matrix is unacceptable please call customer service at 1-800-245-5615.

Method Reference:

AOAC 993.14- Trace Elements in Waters and Wastewaters by ICP-MS with modifications
AOAC 2006.03- As, Cd, Co, Cr, Pd, Mo, Ni, Se in Fertilizers by Microwave Digestion and ICP-OES Detection with modifications

Method Description:

Samples are prepared by microwave closed vessel digestion with nitric acid. Solutions are infused into an ICP-MS instrument to perform identity and quantitation based on the linear response of the elements using calibration standards containing the elements with internal standards.

Information Required by Submitter:

Please supply estimates for solid matrices in ppb (ng/g)
