Title: Peak searching method in spectrochemical analysis apparatus
Inventor: NIWA NAOMASA
IPC: G01J3/02
Filed: 1989-11-30
Abstract: PURPOSE:To shorten the time for peak searching and to execute exact peak searching by comparing the value obtd. by adding the error of the statistical fluctuation component of initially read-out data to this data and the next read- out data. CONSTITUTION:The data on the intensity and wavelength of the characteristic X-rays sampled in a spectrochemical analysis by, for example, an electron beam microanalyzer is stored in a RAM 7 via an I/O interface 5. A CPU 9 processes the data in the RAM 7 in accordance with a program. The CPU 9 successively reads out the data on the intensity and wavelength and judges whether the next data is within the statistical fluctuation component of the previous data by comparing the value obtd. by adding the error of the statistical fluctuation component of the initially read-out data to this data and the next read-out data. As a result, the peak searching is executed by subjecting the data having the change exceeding the statistical fluctuation to smoothing processing. The peak searching is omitted for the data within the statistical fluctuation.
