7 Checking for Leaks
Leaks in Capillary Flow Fittings
For capillary flow fittings, a leak usually indicates that the
fitting has been overtightened. Unless the fitting is obviously
loose, do not tighten it further. Instead, remove the connection,
trim the column end, and install it again. (See To Attach a
Capillary Column Using SilTite Metal Fittings.)
Also inspect the plate and connection for a broken column tip.
