4.4.2 Capillary Connections in an UltiMate 3000 System

Note the following:

• Different fitting systems are used in an UltiMate 3000 system. Therefore, install the

capillaries and fittings only at the positions for which they are intended.

• Viper and nanoViper fitting connections

Loosen or tighten the Viper connection only using the black knurled screw and only with

your hand (do not use tools). The knurled screw can be easily removed and reattached to

the capillary at any time. If you observe leakage on the connection, tighten the screw a

little further. If leakage continues, remove the capillary, clean the capillary ends carefully

by using a cloth or tissue wetted with isopropanol, and reinstall the capillary. If the

connection continues to leak, replace the Viper capillary.

When connecting the Viper capillary to the detector inlet, observe the guidelines in the

Installation Instructions shipped with the capillary.

Capillaries with Viper fitting connections can be reused also for a different connection.

• Conventional fitting connections (non-Viper)

Do not over-tighten these fitting connections. If you observe leakage on the connection,

tighten a little further.

If leakage still exists, first consider cleaning the connection port with a cleaning swab

(part no. 6040.0006). Replace the capillary and/or fitting if this does not eliminate the

problem.

Reuse used fittings and ferrules only for the same capillary connection. This is to avoid

increased dead volume or damage to the system and leakage.
