Abstract
The absorption spectra of pure vit. A and vit. A esters have been detd. in cyclohexane, ethanol, and 75% ethanol. Three wave lengths, X max. and the 2 wave lengths where E is 6/7 of E max., have been selected. By their aid, irrelevant absorption in liver oil is readily detected and corrected.This publication has 4 references indexed in Scilit:
