A fast, single column high-performance anion exchange chromatography with pulsed amperometric detection method for the determination of saccharides in atmospheric aerosol samples was written by Patil, Sachin;Rohrer, Jeffrey. And the article was included in Journal of Separation Science in 2022.Name: (2R,3S)-rel-Butane-1,2,3,4-tetraol This article mentions the following:
Saccharides, especially anhydro sugars present in atm. aerosols, can be used as tracers to track sources of atm. aerosols. High-performance anion-exchange chromatog. with pulsed amperometric detection is a commonly used technique for determining these saccharides, but the reported methods suffer from three drawbacks. First, to achieve separation of the complete set of atm. saccharides, run times are very long, typically longer than 60 min. Second, some methods require two columns to achieve the desired separation Finally, in an era when electrolytic eluent preparation allows for excellent precision and accuracy, these methods require manually prepared eluents, which can lead to separation inconsistency for closely eluting analytes. These drawbacks make existing methods difficult to automate. To address this issue, we developed a fast method that uses only a single column for separation and electrolytically generated eluent that resolves 12 key atm. aerosol saccharides in 20 min. The resolved saccharides include anhydro sugars (levoglucosan, galactosan, and mannosan), sugar alcs. (erythritol, xylitol, and mannitol), and mono-/disaccharides (arabinose, galactose, glucose, mannose, fructose, and sucrose). To our knowledge, this report is the first instance of achieving such a significant reduction in run time with good resolution for this set of saccharides. In the experiment, the researchers used many compounds, for example, (2R,3S)-rel-Butane-1,2,3,4-tetraol (cas: 149-32-6Name: (2R,3S)-rel-Butane-1,2,3,4-tetraol).
(2R,3S)-rel-Butane-1,2,3,4-tetraol (cas: 149-32-6) belongs to alcohols. Alcohols are among the most common organic compounds. They are used as sweeteners and in making perfumes, are valuable intermediates in the synthesis of other compounds, and are among the most abundantly produced organic chemicals in industry. Grignard and organolithium reagents are powerful tools for organic synthesis, and the most common products of their reactions are alcohols.Name: (2R,3S)-rel-Butane-1,2,3,4-tetraol
