I am trying to determine the alcohol % in different hand sanitizers and running into some issues with gel matrix. The results I am getting are about half of what I am expecting. I am following USP <611> alcohol determination for my sample prep which is:
Dilute sample to ~2% sample concentration in water.
Even though alcohol is soluble in water, will I need to switch to a different solvent in order to extract all the ethanol.
Any help very much appreciated.
