PURPOSE:To enable a correct analysis with an accurate detection of the boundary section between ion component zones of different types by automatically changing computation conditions according to detection signal levels. CONSTITUTION:A data processor 3 of an electrophoresis analyzing system 1 reads detection signals P from an equispeed electrophoresis analyzer 2 every short time of t sec to calculate a mean M and then, a time variation value of the value M to be compared with the threshold variation value D. Then, a time gradient G is calculated and compared with the threshold gradient value S. When the value G exceeds the value S and the value V exceeds D immediately thereafter, this, it is judged, points to the boundary section between the ion component zones of different types. By this procedure, boundary sections are detected between the leading ion L and the ion component I1, the ion components I1 and I2, the ion components I2 and I3 and the ion components I3 and the terminal ion T respectively to obtain the potential gradient value and zone length of each ion component zone. Thus, all the components are analyzed separately and the results supplied to a plotter 4. |
