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.
