Determination of traces of methylamine, dimethylamine, and trimethylamine in methylpyrrolidone using cation chromatography with direct conductivity detection.
- AN-C-096Trace analysis of monovalent cations in an ethanolamine matrix (secondary cycle of a pressurized water reactor) using Metrohm Inline Sample Preparation with an 800 Dosino for liquid handling
Methylamine (MMA), dimethylamine (DMA), and trimethylamine (TMA) in methylpyrrolidone using Metrohm Inline Matrix Elimination.
- AN-C-180Bicine in gas sweetening solvent by cation chromatography
Bicine (2-(Bis(2-hydroxyethyl)amino)acetic acid) is a corrosive component. It has to be avoided in acidic gas sweetening solvents. These solvents are based on organic amines. Bicine is amphoteric, holding a carboxylic and an amine group. Under the applied conditions, the amine groups are at least partially protonated and therefore may be separated by cation chromatography. The detection mode is direct conductivity detection.
- AN-COR-019Determining the corrosion rate with INTELLO
Tafel analysis is an important electrochemical technique used to understand reaction kinetics. By studying the Tafel slope, it reveals the rate-determining steps in electrode reactions, aiding fields like corrosion and fuel cell research. This method helps industries optimize processes and improve device performance by tailoring materials and conditions for greater efficiency.
- AN-N-009Carbonate in an amine solution
Determination of carbonate in a solution of methyl-monoethanol-amine with anion chromatography with direct conductivity detection.
- AN-O-035Acetate and formate in amine solutions
Determination of acetate and formate in an amine solution using anion chromatography with conductivity detection after suppression.
- AN-O-046Organic acids in gas sweetening solvent by ion-exclusion chromatography with inverse suppression
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, and butyric acid) is achieved by ion-exclusion chromatography with conductivity detection after inverse suppression.
- AN-S-229Oxalate, thiosulfate, and thiocyanate in amines
Determination of oxalate, thiosulfate, and thiocyanate in an amine solution using anion chromatography with conductivity detection after chemical suppression.
