I have Rice Husk biomass and want to get the CHNS composition without using CHNS Analyzer. Are there any other ways without using a CHNS analyzer to get the CHNS composition like TGA?
Thank you.
Hello Hari, Thank you for your question.
Elemental analysis used to be done by burning the sample and absorbing the gases of combustion in different solutions, which were then weighed. Modern elemental analyzers accomplish the same task with much smaller sample amounts. Unfortunately, you will not be successful with TGA for this question, since C, H, N and S would have to be released one after the other when heating the sample. In addition, you would have to know exactly in which form the compounds are released.
I wish you much success for your research.
I agree with Florian, but there are some alternatives. You can use XPS spectroscopy to obtain an elemental analysis. It is not as accurate as ICP-MS, but it is a common feature on electron microscopes and provides an alternative. You probably will not be able to measure H this way, but you will be able to measure any inorganics.
Not sure why you are avoiding ICP techniques. They are accurate, widely available, and relatively inexpensive.
You can use TGA to obtain the proximate analysis of the rice husks. Then from proximate analysis, the ultimate analysis can be obtained numerically.
There is a relationship between Fixed Carbon, Moisture content, Volatile matter, ash content, with CHNS.
Thank you Vianney Andrew Yiga . There are equations for CHO content using FC, Moisture, VM, and Ash content but there are no equations for N and S. Can you please let me know if there is a way to get these N and S content?
