Answer 2

We should you prefer dry-ashing to wet-ashing of a food sample such as cabbage due to the following reasons -

• Wet-ashing is mainly used in the preparation of various samples for subsequent analysis of some particular minerals. It generally breaks down and removes the organic matrix surrounding those minerals so that they are finally left in an aqueous solution.
• The primary advantages of the dry-ashing method are its lower blank levels, enhanced background current, and its ability to handle significantly larger amounts of sample.
