Separation of Heat Stable Amine Salts in MDEA Solutions Using High-Pressure IC
19 Feb 2015Crude natural gas (methane) must be chemically processed to remove impurities before the gas can be sold as a pure product. This study shows the determination of the anions in mixtures of both common inorganic anions and heat stable amine added to methyldiethanolamine solutions. The anions were separated by anion-exchange chromatography using a Thermo Scientific™ Dionex™ IonPac™ AS11-HC-4µm high-efficiency guard column and detected using suppressed conductivity.

UHPLC and HPLCHigh performance liquid chromatography (HPLC) and ultra high performance liquid chromatography (UHPLC), also known as UPLC, are analytical techniques used to separate, identify and quantitate components of complex mixtures including biological samples such as proteins and lipids as well as chemical mixtures of pesticides, drugs and oils. Both techniques are liquid chromatographic methods but differ by operating pressures (HPLC < 6000 psi < UHPLC ). Components of HPLC and UHPLC systems include columns, detectors, pumps, autosamplers and column heaters. Explore a range of UHPLC and HPLC columns for your specific sample needs including reverse phase, normal phase, ion exchange, HILIC, ion exclusion and size exclusion columns. For more specialized HPLC, explore FPLC, countercurrent LC and simulated moving bed systems.
