Abstract

In order to solve the problem of baseline drift caused by spectral lines of oil spectrometer, an adaptive niteratively reweighted penalized least squares method is proposed to correct the baseline. The oil spectrometer of Kunshan Soohow Instrument Technology Co. Ltd. was used to measure the contents of various elements in the standard oil with four concentrations of 0ppm, 10ppm, 30ppm and 50ppm. The spectral line data collected by the first CCD was processed, and a good baseline correction effect was obtained.
