The analyzer should be regularly serviced to guarantee optimal performance and maximize the life span of the
Cedex HiRes Analyzer.
This includes the following maintenance procedures:
Recurrent manual maintenance and cleaning routines when necessary.
Cleaning routines with the Liquid Management.
Cleaning and maintenance of the syringe module.
Maintenance of the capillary tubes.
Maintenance of the fl ow chamber, the scanner and the 8-way valve. This maintenance routine must be
carried out only by an authorized Cedex HiRes System service technician.
This chapter provides detailed instructions and guidelines for each individual cleaning and maintenance
procedure.
1 Cleaning and Maintenance Check List
This checklist shows when each cleaning and maintenance routine should be done.
Carry out these routines on a daily basis:
LM Shutdown: always after the last measurement and before a Cedex HiRes Analyzer shutdown.
If a Prime has been scheduled to be automatically run the next morning, the Hardware Management should
not be shut down as a Prime can only be run when the Hardware Management is active (see “ Scheduling
Automatic Cleaning Routines ”).
Standard Clean: after the fi nal measurement of a set of samples or before a longer pause between
measurements.
Chamber Clean 2: at least twice a day.
Carry out this routine on a weekly basis:
Intensive Clean
Change of Trypan Blue solution
The following routine should be done every week for users that refi ll reagents themselves:
Empty the reagent containers and the waste container.
Thoroughly clean the containers.
Refi ll the reagent containers (see “ Refi lling Containers Individually “)
Carry out this routine on a bi-monthly basis:
Special Intensive Clean: at least twice a month with 0.1 – 1 N HCl instead of detergent.
Carry out these routines on a regular basis (once a week or after 250 measurements):
Clean the casing, Reagent Tray, Multi Sampler housing (if installed) and Reagent Port by wiping down with
70% alcohol and a lint-free cloth.
Run a focus adjustment of the analyzer every month or after any change of position or vibration of the
measurement system.
In order to ensure that the Cedex HiRes Analyzer is fully operational, an Intensive Clean must be carried out
once per week even if the system is not in use for measurements.
