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.

10 ng/g (ppb)
Sample Size Requirements:
Inductively Coupled Plasma Mass Spectroscopy (ICP-MS)
7-9 business days
Is rush testing available?
AOAC 993.14 and 2015.06
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).
Poor recovery may be obtained for tin due to the instability of the metal post digestion in the absence of using hydrofluoric acid.
