An Improved Ion Chromatography Method for …
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 for-mate. Baseline resolution is achieved in min using anAS11-HC anion exchange column with 4 mM NaOH eluent mL/min flow rate. The detection limits are 12 g/mL( ng) for acetate and 11 g/mL ( ng) for Method was successfully used for air quality monitor-ing in a Los Angeles museum indoor and outdoor air quality requires accurate collection andquantification of volatile organic compounds.
is calculated based on Fick’s law of diffusion, using equation 1: C=Lm/DAt (1) where L is the length of the tube, m is the mass of acid collected, Dis …
