چکیده    In this work, an improved single-column chromatographic (iscc) separation process is proposed. the term “improved” represents both conceptual and physical modifications compared to the available single-column processes, including a novel fraction collection scheme and allowing overlapped peaks from adjacent cycles. in addition, the fraction collection mechanism was modified in order to facilitate online monitoring. another advantage of the iscc process is that its large degree of freedom as injection volume, cycle time, solvent flow rate, feed concentration, and fraction-collection intervals can all be decision variables in this process. the experimental implementation and validation are covered in this work. the results indicate the successful operation of the iscc process and accompanying peripherals for the separation of guaifenesin enantiomers. in particular, the tests confirmed the integrity of the online monitoring system and proved the capability of the process for 98 % purification of the tested enantiomers with an advantageously shorter cycle time, resulting in higher productivity.
