<p>Dosing a liquid volume comprises immersing a sample holder with a liquid passage into a liquid, applying a low pressure produced by a gas displacement system to the gas passage of the holder, regulating the drive of the gas displacement system to produce a constant working low pressure, determining the volume using the post-regulated drive path of the drive, comparing the determined volume with an amount of volume to be received, reducing the low pressure applied on the holder when the volume amount is reached, removing the holder from the liquid, directing the holder to a release site, determining flow parameters from the volume received, working low pressure and the time for receiving the volume, applying a high pressure to the gas passage of the holder, determining the time with the aid of the flow parameters and the high pressure and reducing the high pressure when the time point is reached. An independent claim is also included for a device for dosing a liquid volume.</p> |
