posted on 2004-10-08, 00:00 authored by Jacqui AdcockJacqui Adcock, Neil BarnettNeil Barnett, Richard Gerardi, Claire Lenehan, S LewisThe mono-isopropylamine salt of glyphosate was selectively determined directly in industrial and commercial formulations using flow injection analysis with tris(2,2′-bipyridyl)ruthenium(II) chemiluminescence detection without the need for separation. Glyphosate and its mono-isopropylamine salt furnished detection limits of 7×10−9 and 3.5×10−10 M and relative standard deviations of 0.4% at 1×10−7 M and 0.8% at 5×10−8 M, respectively. The methodology is robust and reliable with samples subjected only to aqueous dilution prior to analysis.
