I have a ethanol-water 50% extract of mango peel. I purified mangiferin from the extract with filtration and precipitation. so i obtained a low concentrated extract which i want to se the IR spectrum and compare with the mangiferin IR spectrum. however, I would like to know what concentration should i achived to obtain a good IR spectrum from liquid samples (Standard and Extract), Also how many sample should I need in mL. Any advise would be really usefull. PD: I have not enough standard or extract to make a solid sample lecture with KBr.
