Ashing using a muffle furnace is often used for the analysis of plant tissue samples. Generally speaking, the entire ashing process takes 4-8 hours. Microwave ashing can shorten the ashing time to 20 minutes. In this paper, six different plant samples were ashed using two techniques, and the results of ashing were compared. Then, ICP spectroscopy was used to analyze the macro and micro nutrients of the plant. After ashing in a microwave muffle furnace for 40 minutes, the results of all nutrients are compared with the results of the 4-hour ashing in a traditional muffle furnace. The results show that microwave ashing technology can significantly improve the analysis speed and time.
