Rotary turret and reusable specimen holder for mass spectrometer
This patent describes a turret assembly for rotatably supplying material samples for mass spectrographic analysis. It comprises: holder means for mounting the material samples with each of the material samples exposable for the spectrographic analysis; rotatable electrical radial contact means for heating a first of the samples for analysis and heating a second of the samples for pretreatment where the second sample is angularly separated from the first sample for effective contamination control; substantially solid body means for supporting and relatively rotating the electrical radial contact means and the holder means while aligning the holder means for the spectrographic analysis; and housing means about the holder means and the rotatable electrical contact means for establishing and maintaining a vacuum.
