This example describes the processing of a queue with six samples.
The columns 'Chrom. No.' and 'Dialysis No.' are just given for
information. Please note that in the 788 program of 'dialysis.smt' not the
given sample position 'Vial' is used; it is increased by 1 to start dialysis
of the next sample. Therefore, all samples have to be arranged on the
sample rack in a closed line.
