Abstract:
1. A device for preparing samples for ionization in a mass spectrometer, comprising: a table for receiving a sample support having a plurality of sample sites, the table comprising a first turntable and a second turntable mounted eccentrically on or in the first turntable, the sample support being located on the second turntable and the turntables being eccentrically connected as to provide for a coupled motion wherein rotating the first turntable moves the second turntable, but rotating the second turntable does not move the first turntable; a dispenser for dispensing liquids onto sample sites of the sample support on the table, the dispenser being installed in a fixed position so that it does not rotate; and drives, connected to the turntables, for positioning the dispenser and the sample support table relative to each other by rotational movements of the turntables about two eccentric axes; wherein the rotational movements of the turntables allow any sample site of the sample support to be positioned under the dispenser.
