A column ranking system effectively aids in selecting appropriate columns for pharmaceutical chromatographic analysis, ensuring reliable separation of drug substances from impurities.

Area of Science:

  • Pharmaceutical analysis
  • Chromatography
  • Method development

Background:

  • Accurate separation of drug substances from impurities is crucial in pharmaceutical quality control.
  • Selecting the optimal chromatographic column is essential for achieving efficient separations.
  • A previously developed classification system for column selection requires performance validation.

Purpose of the Study:

  • To investigate the performance of a developed classification system for selecting chromatographic columns.
  • To evaluate the system's utility in separating seven different drug substances from their impurities.

Main Methods:

  • Pharmaceutical chromatographic analyses were performed for six drugs (acetylsalicylic acid, clindamycin hydrochloride, buflomedil hydrochloride, chloramphenicol sodium succinate, nimesulide, phenoxymethylpenicillin) following European Pharmacopoeia (Ph. Eur.) monographs.
