Claim 16:
17. A computer program product on a data medium, comprising a sequence of operating instructions executable through an electronic computing unit, which executed on an electronic computing unit, which is linked with a pipetting device according to claim 1, so as to allow signal transmission, effects the execution of the the following steps:
determining a target residual quantity value, which represents a residual quantity of dosing liquid remaining in the pipetting channel at the end of the dispensing sequence,
determining a working gas pressure associated to the represented target residual quantity which is required in order to maintain the target residual quantity in the pipetting channel in a predetermined state,
actuating a piston drive for adjusting the determined working gas pressure in the pipetting channel,
after adjustment of the determined working gas pressure in the pipetting channel: acquiring the piston position of the pipetting piston,
comparing the acquired piston position with a target piston position associated to at least one of the represented target residual quantity and the determined working gas pressure, and
producing an output representing the determined dosing quality as a function of the comparison result representing the dosing quality of the dispensing sequence.
