HPLC Column Classification - USP - Stimuli to the Revision Process

ACD Column Selector - the six chromatographic column parameters

SFC test for an extended ODS HPLC column classification (Article 1)
SFC test for an extended ODS HPLC column classification (Article 2)
SFC test for an extended ODS HPLC column classification (Article 3)
     This test provides, from a single analysis of carotenoid pigments, the absolute hydrophobicity, the silanol activity and the steric separation factor of the ODS stationary phases.

HPLC Column Classification System (Katholieke Universiteit Leuven)
     More than 80 different types of ODS columns were characterized by 4 column parameters, which can be determined with 3 simple, fast, repeatable and reproducible chromatographic methods.
The Test Procedure (Katholieke Universiteit Leuven)

www.hplccolumns.org
     This website is a a free, online resource for selectivity data and tools for High Performance Liquid Chromatography. The current database contains column parameters for over 500 reversed-phase HPLC columns characterized using the Hydrophobic Subtraction Model of reversed-phase selectivity.

U.S. Pharmacopeia Column Equivalency Database
     The USP Database was developed by the USP Working Group on Column Equivalency using the NIST SRM 870. All data being displayed was generated by the column manufacturers after evaluation of the chromatographic phase.

ACD Column Selector (runs within the chemical drawing tool ACD ChemSketch Freeware)
     The columns are evaluated by 6 parameters (ligand density, hydrophobic sensitivity, shape selectivity, hydrogen bonding capacity, and total and acidic ion-exchange capacity). Since each parameter can be targeted individually, chromatographers can also search for columns that have high coefficients for a certain term, allowing them to change their columns to target a given structural aspect.

USP-NF Chromatographic Columns Online Database
The Chromatographic Columns online database is a compilation of the chromatographic columns used to validate the chromatographic procedures in USP–NF, Pharmacopeial Forum, Revision Bulletins, and Interim Revision Announcements. It provides a cumulative listing of columns referenced in gas and liquid chromatographic methods related to revisions made to USP–NF since January 1980.
Access
Chromatographic Columns, previously a print publication, is now a free, online database. To begin using the database, a one-time registration is required.  Also, after log in, Terms of Use must be agreed to before proceeding to the data.
