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.

TN122: Separation of Heat Stable Amine Salts in Methyldiethanolamine (MDEA) SolutionsUsing High-Pressure IC

Instrument Type: IC

Sour gas is treated with amine and recycled amine (scrubbing) solutions to absorb toxic and undesirable H2S and CO2 create sweet natural gas. Salts of organic acids and sulfur species, heat stable amine salts (HSAS) can concentrate over time. Analysis of these HSAS are needed to assess the efficiency of scrubbing solution and can be quite challenging. In this technical note, HSAS in methyldiethanolamine (MDEA) were separated with high efficiency on a 2 mm i.d. IonPac AS11HC-4μm column using a high pressure ion chromatography system.

Determination of Anions in an Artificial Volcanic Gas Condensate Sample on 2 mm IonPac AS25 Column

Instrument Type: IC

Determination of Anions in an Artificial Volcanic Gas Condensate Sample on 2 mm IonPac AS25 Column. This sample simulates a volcanic gas condensate sample containing 100 mg/L carbonate, 10 mg/L sulfate and ppb to ppm concentrations of halides, sulfite, thiocyanate, and thiosulfate.
