6.1.4 Shutting down
If the instrument is not used for a longer period, the whole IC system
(except the columns) must be rinsed salt free with methanol/ultrapure
water (1:4), in order to prevent eluent salts and reagents from forming
crystals which may cause subsequent damage.
Rinsing salt free the IC system
To rinse the system, proceed as follows:
1 Remove the separation column from the eluent path. Connect the
connection capillaries directly with each other using a coupling
(6.2744.040).
2 Rinse the IC system with methanol/ultrapure water (1:4) for 15
minutes.
Rinse with eluent for at least 15 minutes at starting up again and before
connecting the guard column and separation column.
6.2 Door
Caution
The door is made of PMMA (polymethylmetacrylate). It must never be

Caution
Never hold the instrument at the door when lifting or moving.
