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.

www.hplccolumns.org
http://www.hplccolumns.org/database/compare.php
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.
