Abstract
The invention provides a glow discharge optical emission spectrometer for intermittently applying a high frequency voltage to a sample and obtaining a measured value from a spectroscope in synchronization with a timing of a unit of application during intermittent application. The obtaining of measured values in which is introduced noise at a non-application time during intermittent application is prevented, and by applying a high voltage value to the sample with a minimized adverse effect on a voltage application to the sample, high-level measured values are obtained. By obtaining a measured value a plural number of times during a unit of application, a large number of measured values are obtained in a short period of time, resulting in a reduction in measurement time.
