4.6 Standard methods
The following pages contain the listing of standard user methods in-
cluded with the instrument with explanations of the important com-
mands. A prerequisite for the use of these methods is a correct con-
figuration of the 766 IC Sample Processor for the 6.2041.430 sample
rack supplied (M129-2).
The user methods are designed for IC systems with the Metrohm in-
struments 732 IC Detector, 733 IC Separation Center, 709 IC Pump,
752 Pump Unit, 753 Suppressor Module, and 754 Dialysis Unit and the
PC evaluation program «IC Metrodata». The specific IC methods have
to be programmed at the 732 IC Detector or via PC program «IC Met-
rodata». Details for the connection of these instruments to the remote
connection 22 22 can be found in section 2.4.
It is recommended to work through every new method step-by-step
with the TRACE function, making adjustments where necessary, before
starting the method for the first time.
4.6.1 Method "PC"
Application
Processing a queue with the PC program «IC Metrodata» with the PC
as "Master".
Interconnection
