Method of electronic calibration of the measurement channels of multichannel analyzers of atomic emission spectra

Multichannel analyzers of atomic emission spectra: Current state and analytical potentials

“…The structure of the arrays of photodiode BLPP 369 enables one, in the absence of radiation, to electronically obtain the relation between the value of the output signal and the voltage at the input of the measurement circuit, that is, to implement its calibration in an automatic mode [7]. The residual nonlinearity of the measuring channels is less than 0.5%.…”
