2.8 Dosing and liquid handling
Metrohm 838 Advanced Sample Processor, Operation 59
2.8.2 Liquid handling functions
The Sample Processors can use the numerous capabilities of a
Metrohm Dosino (700 or 800) to the full extent. The four ports of the
Metrohm Dosing units for the Dosino can be used as outlet or inlet
ports as defined by the user. This means that not only simple addition
and filling tasks can be carried out, but complex liquid handling tasks
such as pipetting or sample transfer can be carried out without any
problems.
The dosing functions of the Metrohm Sample Processors are to be
used in such a way that, in addition to the function, the port at which the
function is to be carried out is also given. This means the Dosing unit
inlet or outlet to which the stopcock first moves in order that the re-
quired function is carried out.
