[Conventional technology 1 In the conventional liquid chromatography system,
For detection devices and liquid gradient devices, it takes 30 minutes to 1 hour before the power supply device can measure, that is, until the light source of the detection device or the flow rate controlled by the liquid gradient device stabilizes. . Therefore, as a means for users to immediately start measurements when dispatched, a timer function is installed in the personal computer that controls the liquid chromatography system to output a pulse signal after a specified time, and all liquid chromatography The system has been started up by inputting this pulse signal to a power supply that cuts off and on the power supply to the device all at once. Furthermore, when continuous nighttime measurements are performed in combination with an autolampcer, the pulse signal is similarly input to the power supply when the system is shut down at the end of the measurement. In addition, one liquid chromatography
When multiple users alternately use a system with different system configurations, it is necessary to change the power supply connection each time.
