To connect capillaries with conventional fitting connections (using ferrules) (non-Viper), follow these steps:
Insert the capillary into the connection port.
Tighten the connection with a wrench (wrench size: 1/4").
NOTICE
Overtightening may damage the connection (both, the ferrule and the connection port). With a torque wrench, the torque should not exceed 3 Nm (for steel capillaries).
Check whether the connection leaks. If leakage exists, follow the steps further down.
Resolving Leakage with Conventional Fitting Connections
Remove the capillary.
Clean the connection port with a cleaning swab.
Reinstall the capillary.
If the connection continues to leak, install a new capillary.
NOTICE
To avoid increased dead volume, leakage, or damage to the system, reuse fittings and ferrules only for the same capillary connection.
