PURPOSE:To simplify execution of signal processing, statistic processing, filing, etc., by controlling peripheral devices constituting a sample concentration measurement system with a biosensor by means of a personal computer and inputting sensor output signals into the personal computer. CONSTITUTION:A sample analyzer comprises a personal computer 1 in addition to a biosensor input board 2 and a D/A board 3 as its extension boards. A biosensor 4 for sensing a target to be detected in a sample is connected to the biosensor input board to amplify sensor signals, and they are input into the personal computer after being offset-correction to be subjected to signal processing, statistic processing, filing, etc. The D/A board is used to control a stirrer 5. Further after sample concentration measurement, a liquid feeder 9 is operated via an RS232C terminal board 8 to clean the sensor. Not only analysis is possible only with operation of a keyboard of the personal computer but also signal processing and statistic processing are possible. |
