AN85: Determination of Trace Anions in (Acetone) Organic Solvents Be the first to rate this application

an85 determination trace anions acetone organic solvents


The determination of trace anionic contamination in processing solvents (N-methyl-2-pyrrolidone, isopropyl alcohol, and acetone) is important to the electronics industries to minimize corrosion. Here matrix elimination is used to retain and concentrate µg/L anionic contamination in a 5 mL acetone sample onto a concentrator column. Acetone is flushed to waste (5 min) with purified deionized water (10 mL). Trace anions are eluted from the concentrator and separated on IonPac AS9-HC column using 8 mM carbonate, 1.5 mM NaOH eluent. AU163 updates AN85 with < 0.2 ug/L lower detection limits.
