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

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
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)
This test will only measure total Chromium (both organic and inorganic). For a measurement of total Chromium as well as a measurement of the organic and inorganic Chromium please contact customer service at 1-800-245-5615.
