Abstract
The present invention relates to a method for simultaneously qualitatively and quantitatively analyzing compounds of aldehydes and/or ketones in a short time by using an optimal TLC plate, a proportion of a developing solvent, a sample amount, etc., and can provide an analysis result equivalent to a conventional analysis result in a shorter time by providing the most optimal conditions when using the TLC method.
Claims4
A method for analyzing aldehyde or ketone, comprising:
- (i) injecting a sample of the aldehyde or the ketone into a cartridge containing 2,4-dinitrophenylhydrazine (2,4-DNPH) to obtain a 2,4-dinitrophenylhydrazone derivative;
- (ii) extracting the 2,4-dinitrophenylhydrazone derivative obtained during the injecting with a solvent to produce an extract;
- and
- (iii) analyzing the extract by thin layer chromatography (TLC) to identify aldehyde or ketone derivatives corresponding to the aldehyde or the ketone of the sample,
- wherein the sample of the aldehyde or the ketone is injected in an amount of 0.3 to 0.7 μL, and
- wherein the analyzing the extract by TLC is performed using a developing solvent which is a mixed solvent of ethyl acetate (EA) and hexane (Hex) of 1:8 to 1:12.
