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

an85 determination trace anions nmethylpyrrolidone organic solvents


The determination of trace anionic contamination in processing solvents (N-methyl-2-pyrrolidone (NMP), 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 NMP sample onto a concentrator column. NMP 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.
