AB105: Anions and Organic Acids in Wood Extracts

Instrument Type: IC

This application demonstrates the analysis of inorganic anions and anions of organic acids in waste liquor from wood extracts. The sample matrix and the contaminant were removed from the components of interest using an IonPac NG1 column as an additional guard column. This application requires an autosampler equipped with 10-port valve. With this configuration, IonPac NG1 column is placed in line with the analytical column, while a second column rinsed in counter flow direction with acetonitrile/water, followed by a conditioning step using sodium hydroxide.
