Hi Davoud, a common method for qualitative and quantitative detection of aldehydes is derivatization with 2,4-Dinitrophenylhydrazine and analysis by HPLC (e.g. https://www.agilent.com/cs/library/applications/5991-1545EN.pdf). Greetings Markus

Davoud Ghazanfari

Dear Chandan, what column do you suggest for doing so, also do you know how to calibrate it and how make standards?

Thanks
