Pj. Baxter et al., AN APPARATUS FOR THE DETERMINATION OF VOLATILE ANALYTES BY STOPPED-FLOW INJECTION-ANALYSIS USING AN INTEGRATED FIBER OPTIC DETECTOR, Talanta, 41(3), 1994, pp. 347-354
A new method for the analysis of volatile analytes using a stopped-flo
w injection system originating from either a gas or liquid phase has b
een developed. It uses an integrated fiber optic detector which also s
erves as a reactor. This system combines the advantages of gas diffusi
on and stopped flow, making the overall assay very sensitive. Both gas
streams and aqueous solutions containing ammonia were analyzed. The l
imits of detection are 40 ppb for gas phase analysis and 1.0 ppm for a
queous phase analysis.
