The present disclosure provides chromatography columns and methods of chromatographic separation using the same. In particular, the disclosure provides modified columns where the cross-sectional area of the column increases in an area near the end of the column in a flared manner. The modified columns can be used in Expanded Bed Absorption (EBA) systems.

This invention relates generally to a process for selective adsorption and recovery of lithium from natural and synthetic brines, and more particular to a process for recovering lithium from a natural or synthetic brine solution by passing the brine solution through a lithium selective adsorbent in a continuous countercurrent adsorption and desorption circuit.

The present disclosure relates to an improved method for producing allulose and, more particularly, to a method for preparing a fructose-containing raw material solution by using raw sugar as a raw substrate used in the production process.
