Technical data sheet
Print- 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.
- Acceptable matrices
Food Products, Food Ingredients, Nutraceuticals, Beverages
- Unacceptable matrices
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), pure fats and oils, glycerin and glycols, volatile flavoring agents, and alcoholic beverages. If you have a question regarding your matrix, please call customer service at 1-800-245-5615.
