Ash testing is done at different temperatures depending on the method used.
Dry ashing is typically done at temperatures around 500 degrees Celsius. In this method, a sample is placed in an ashing furnace and heated to burn away organic material. The resulting ash can then be analyzed to determine the mineral composition of the sample.
Wet ashing, on the other hand, uses acids instead of high temperatures to break down the sample. The temperature range for wet ashing is typically set at 350 degrees Celsius. This method is faster than dry ashing and is commonly used for food samples.
It's important to note that the specific temperature used for ash testing may vary depending on the type of material being tested and the specific requirements of the analysis. Different materials may require different temperatures to effectively burn away organic material and obtain accurate results.
In summary, ash testing is done at temperatures around 500 degrees Celsius for dry ashing and around 350 degrees Celsius for wet ashing. These temperatures allow for the complete combustion of organic material and the determination of mineral composition in the sample.
