6. Open system file 'dialysis.smt', again. Select Control/Connect to

Workplace and save it under the new name 'end-dialysis.smt'.

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.
