Question on proper way to condition a capillary column.   Do I have to disconnect the column from the detector to condition my column?   The column has been in use for several months. 

Thanks,

Tom

I assume the column is already installed and therefore I would leave it as it is. If you were conditioning a NEW column, I would NOT install on the Detector end. Hope that answers your question

Thanks for your reply.  Can I condition my column often with the column connected to the detector without causing any harm to the detector?  My column has be installed for over 6 months now.

thanks again,

Tom

Technically, your column should not need to get conditioned by 'baking' very often. Specially, if it is left on the system. I wouldn't by default bake your column each time. You can also condition the column by running test injections-possibly of the standards. I know we have a column where we run test injections for hours for it to get conditioned. We only 'bake' the column when these test injections don't look like they are getting progressively better (assuming running test injections of the standard or blank is ok where you work at). We run them but we document these test injections appropriately (for Audit purposes)
