Abstract

PURPOSE: To increase the accuracy of reproduction for the analysis data, by obtaining both the holding time and the column efficiency for one of the identified uric acid, hippuric acid and indole acetic acid each and then displaying them with every execution of analysis.
CONSTITUTION: The three components, the uric acid, hippuric acid and indole acetic acid, are contained in a high probability in any kind of urine. Thus if both the holding time and the peak duration are obtained for either one of the above three components, the monitor is possible for the state of the separation column 5. Based on the holding time and the peak duration, the column efficiency is obtained via the data processor 12 and with every execution of analysis and then displayed on the display unit 11. The initial value of both the holding time and the column efficiency each is written into the magnetic card 17 through the input key panel 19 and under the condition of each column and separation. And in case the column efficiency of every execution of analysis shifts to the initial value and by an amount over the fixed range, the microcomputer 18 stops the operation of the liquid sending pump 3 via the control interface 16.
