The main application areas of GDX-203 filling columns are summarized and summarized in a table:
Examples and Characteristics of Specific Analytical Substances in Application Fields
Alcohol analysis of methanol, ethanol, trace water, etc. does not require a fixed liquid and can directly analyze ethanol methanol water mixed systems with good separation efficiency.
Trace water analysis in chemical products enables rapid determination of trace water in various organic chemical products.
Organic solvents and impurities analysis, such as ethyl acetate, benzene, and acetic anhydride, are suitable for separating compounds with higher boiling points and require a shorter time.
Aromatic hydrocarbon analysis shows that aromatic compounds such as benzene, toluene, and xylene have good separation effects on aromatic compounds.
Specific amine analysis of trace impurities in methylamine (such as dimethylamine and trimethylamine) requires coating with tetraethylenepentamine fixative, which can separate dimethylamine
