Checking for Leaks
Leaks in Capillary Flow Fittings
WA R N I N G

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.
Be careful! The oven, inlet, and/or detector may be hot enough to
cause burns. If the oven, inlet, or detector is hot, wear
heat-resistant gloves to protect your hands.
