%X Air quality monitoring for acetic and formic acid vapours inmuseum galleries and storage environments is commonlyconducted using passive sampling and ion chromatography(IC). We report development of a rapid IC method with 2 to60-fold improvement in detection limits for acetate and formate. Baseline resolution is achieved in 4.5 min using anAS11-HC anion exchange column with 4 mM NaOH eluent at1.5 mL/min flow rate. The detection limits are 12 ¦Ìg/mL(0.24 ng) for acetate and 11 ¦Ìg/mL (0.21 ng) for formate.The method was successfully used for air quality monitoring in a Los Angeles museum warehouse.
