Fig. 13: Connections at sample preparation module of the 833 IC Liquid
Handling Sample Preparation Unit
1 Insert sample preparation module
• Place sample preparation module 33 inside the chamber on
the floor.
2 Connect sample preparation module
• Remove plastic stoppers from the rear panel openings 18 of
the 820 IC Separation Center and lead cable 35 mounted on
sample preparation module 33 back through this opening.
• Connect cable 35 to connection 13 “Module” of the 833 IC
Liquid Handling Unit (see Fig. 2).
3 Connect sample feed to sample preparation
module (Sample Preparation connection 1)
• Connect inlet capillary 36 (marked with “Sample in”) at the
sample preparation module connection 34 (see Fig. 13) to
connection “5” of injection valve B using a 6.2744.010
compression fitting.
4 Connect sample preparation module to valve A
(enrichment column) (Sample Preparation
connection 1)
• Connect outlet capillary (marked “Sample out”) at sample
preparation module connection 34 (see Fig. 13) to
connection “1” of injection valve A using a 6.2744.010
compression fitting.
• When making the further connections to injection valve A
make sure that the ”Inject” setting of the enrichment column
is rinsed in the reverse direction to the “Fill” setting.
