An automatic biochemical analyser
A machine for the automatic analysis of human blood and other body fluids is described. Brief reference is made to the associated biochemistry. The problems of measurement of sample optical density and the control of sample temperature, are discussed, and the considerations leading to the choice of photo-cells for the analysers are considered. The analysing equipment and the means of achieving positive identification of samples are described. The requirements for controlling the machine are discussed and the application of computer-control to the machine and the logging of output data is described.
