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.
