Unknown sample 11 (buffered by 12) and standard 13 solutions are fed alternately to a flow cell and measuring transducer 15 before being exhausted to waste. The transducer derives an electrical output dependent on a parameter of the measured solution and passes it by way of impedance matching circuit 18 and linearising circuit 19 to display 20. A servo system comprising calibration circuit 21 and motor 22 adjusts the response of the system when the standard solution is flowing so that the output is brought within predetermined limits. <IMAGE> |
