ABSTRACT:
An external signal detection circuit is installed in a new measuring section, and generation and end timing of a readout signal of a spectrometric detector is directly controlled, and a readout signal in synchronization with an external start signal is generated. After input of measurement standby instructions, the external start signal is monitored anytime. Before detection of the external start signal, the new measuring section is shifted to a pause state and after the detection of the external start signal, transition to a measurement state is made. By this configuration, delay time between input time of the external start signal and readout start time of data is defined and valid measurable time at the time of setting short storage time is increased.
