Older Columns
Prepacked ready-to-use Shodex columns have a history of about 30 years. Because
of technical modifications after the release of the first product, some of currently
available columns differ from their initial version. Most of these older columns
are still available to users who have been using them for quality control and
so on. However, please note that such old columns may be discontinued in the future.
They are listed below. For details, please contact your nearest representative
office. When starting a new method, we recommend using the high-performance standard
column, indicated below as "Alternative standard column".
