Improvement of Analysis and Transferability in Peptide Purification: From HPLC to FPLC and Back Again.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Optimal purification, high purity and robust purity control for synthetic peptides are critical, as even minor impurities can alter biological activity, distort analytical results and compromise downstream applications. Reliable translation of analytical HPLC results to preparative FPLC conditions remains challenging due to system-specific differences in column geometry, gradient formation and mobile-phase chemistry. This study addresses these limitations through a systematic evaluation of chromatographic parameters influencing peptide selectivity, resolution and transferability. Using a defined peptide impurity library, the effects of gradient steepness, flow rate, temperature and mobile-phase modifier were quantified, revealing that flow-rate optimization and modifier choice have the greatest impact on separation quality. A correction equation was developed to compensate for system-dependent deviations, reducing transfer errors in elution percentage from approximately 17% to less than 5%. The optimized workflow enabled initial preparative purifications with purities above 90% and yields exceeding 30%. Additionally, substitution of trifluoroacetic acid with formic acid was explored as a greener modifier, providing selective improvements in separation performance. The approach establishes a practical and sustainable workflow for the transfer of HPLC-to-FPLC methods for peptide purification.
