Vial autosampler

摘要

Apparatus for spectrophotometric analysis of material in vials 16 in which material in each vial is subjected to a beam 4 at a scanning station 20. An array of the vials 16 is carried by a carousel 60 for each vial 16 automatically and sequentially to be delivered to the scanning station and thereafter removed following scanning by the beam 4. Rotation of the carousel 60 to feed the vials to the scanning station and to remove them from that station is controlled by a computer 3 which also controls spectrophotometric measurement of the material in the respective vials whilst at the scanning station.
