Title:
FIBER-PACKED NEEDLE FOR ALDEHYDE/KETONE ANALYSIS, ANALYTICAL APPARATUS, AND ANALYTICAL METHOD
Document Type and Number:
WIPO Patent Application WO/2007/088916
Kind Code:
A1
Abstract:
A simple method for analyzing aldehydes and ketones in a sample which does not
necessitate a complicated operation comprising extraction with a solvent and
concentration of the extract; and an analytical apparatus and a fiber-packed
needle which are for use in this analytical method. Also provided are fibers coated
with the hydrochloride or sulfate of 2,4-dinitrophenylhydrazine. The needle
is one for microextraction in which these fibers have been packed. The analytical
apparatus comprises this needle and a suction device. The method, which is for
analyzing aldehydes and ketones contained in a sample, is characterized by sucking
a sample through the needle in this analytical apparatus to react the aldehydes/ketones
contained in the sample with 2,4-dinitrophenylhydrazine and thereby convert
them to the corresponding 2,4-dinitrophenylhydrazones, desorbing the hydrazones,
and introducing these into a chromatograph to analyze them.
