Leaks in Capillary Column (Microfluidic) Fittings
For capillary column 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.
Also inspect the plate and connection for a broken column tip.
