Abstract

The system automatically analyzes different chemical samples stored on a turntable. Test tubes containing chemical samples are placed in holders along the periphery of the turntable. On the inside circumference 12 of the turntable are placed labels 14. Each label 14 is associated with the test tube opposite it on the outside circumference of the turntable. The label 14 for a given test tube identifies the test tube.

Computer Controlled Laboratory Sampling and Analysis System

The system automatically analyzes different chemical samples stored on a turntable. Test tubes containing chemical samples are placed in holders along the periphery of the turntable. On the inside circumference 12 of the turntable are placed labels 14. Each label 14 is associated with the test tube opposite it on the outside circumference of the turntable. The label 14 for a given test tube identifies the test tube.

The turntable is indexed counterclockwise past a scanning and sipping station 16. At station 16, test tube 18 is being sampled by a sipping tube 19 and its label 20 is being scanned by optical sensors in protrusion 22 of the turntable.

The scanned information picked up by the scanner is passed to computer 24. This information tells computer 24 which sample is being picked up by tube 19 of sipper 26. Computer 24 has stored in its memory the name of the sample and the tests to be performed on it. The test information from computer 24 is passed to spectrophotometer 28.

Spectrophotometer 28 receives the sample from test tube 18 via sipper 26 and analyzes the sample at different wavelengths specified by the test information received from computer 24. When the tests are complete, the sample in spectrophotometer 28 is dumped and the test results are passed from spectrophotometer 28 to computer 24. The latter then stores the result and/or passes the information to an output terminal such as typewrite...
