The TOC analyzer measures the total carbon content of an organic compound. If you can determine the carbon content of an unknown hydrocarbon, you can determine the empirical formula for a hydrophobic hydrocarbon. This is not enough to determine a hydrophilic compound. Glycerin is a hydrophilic compound. In addition to carbon and hydrogen, it contains oxygen. To determine the composition and structure of such molecules, it is necessary to know the oxygen content.
Thank you Professor Yuri Mirgorod. Could you please suggest any published articles or reference documents for measuring the hydrophilic and hydrophobic organic matters?
The determination of the empirical formula of an organic compound by elemental analysis is studied at school. Usually no reference is made to the solution to this problem. Gives a link to a method for defining elements. The hydrophobicity and hydrophilicity of substances is determined by the contact angle and the wettability of substances with water. Every colloidal chemistry textbook has this section. I recommend you a concise of glossary colloidal chemistry.
