3.2 Cleaning Routines Carried out by the Liquid Management
The Liquid Management plays a key role in the Cedex HiRes Analyzer. It is necessary to Prime the system at the
beginning of the day, and to carry out an LM Shutdown prior to shut down of the system in the evening (see
“Carrying out an LM Shutdown and HW Shutdown”).
The Liquid Management automatically runs an Ultra Fast Clean routine after every sample measurement.
During the Ultra Fast Clean (approx. 30 seconds), the entire Liquid Management system, including capillary
tubes, fl ow chamber and sample port, are rinsed out thoroughly.
Manual cleaning routines can be carried out in the Cleaning window. To open the Cleaning window, click on
the Clean button in the Shortcuts area of the Control Center or select Cleaning routines in the Functions
menu (see Figure 78).

Fast Clean and Standard Clean involve the entire Liquid Management system including capillary tubes, fl ow

port to prevent fl ooding.
Fast Clean (with detergent, and distilled water for approx. 60 seconds)
The entire Liquid Management system is rinsed with distilled water, then with detergent and fi nally with
distilled water. Use this routine between measurements to remove dirt particles and air bubbles quickly from
the fl ow chamber.
