The program number under which the program is to be saved can be selected at will between P 01
and P 10. This option allows an existing program to be loaded, edited and/or viewed and saved under
a new number, whereby the original program remains unchanged.
Creating a new program, example:
Prerequisites:
Two pump modules, e.g. C-605, are installed, each with a solvent. No solvent Valve Set is installed.
A gradient program P02 is created that initially runs for 25 minutes isocratically with pure Eluent A,
then, for 30 minutes, the concentration of Eluent B is continuously increased to 35% and finally this
concentration B is maintained for 20 minutes. Eluent A could e.g. be hexane, and Eluent B ethyl
acetate.
The pressure is 50 bar and the flowrate is 10 ml/min.
