Bicine in gas sweetening solvent by cation chromatography

IC Application Note C–187 UOP 939-96: Basic Nitrogen in LPG by Ion Chromatography Determination of amines in an acetic acid scrubber solution (according to UOP 936-95) applying non-suppressed cation chromatography. Cation chromatograms of a scrubber solution without spike (chromatogram partially…

AN-C-193 Alkyl amines in scrubber solutions Determination of ethanolamines and methylamines besides inorganic cations for process monitoring Summary Scrubber solutions often contain mixtures of alkyl amines. These substances neutralize acidic harmful gases such as H2S and CO2, and remove them…

WHITE PAPER Measuring inorganic cations and amines with ion chromatography mass spectrometry (IC-MS) Two robust and sensitive analytical techniques in their own right – ion chromatography (IC) and mass spectrometry (MS) – can be combined to form an even more…

IC Application Note O–46 Acidic gas sweetening solvents are used to remove acid gases such as H2S and CO2 from streams. Typically, amines are applied as alkaline components in these solvents. The determination of organic acids (glycolic, acetic, formic, propionic,…
