Methodologies preprocessing the fluctuation-noise data in the study of chemical sources of current have been proposed. The object of the study was lithium dioxide-manganese element in the discharge process. Initial measurements were performed on compensated DC voltage chain. The overwhelming trend component of discharge was partially disavowed by linear approximation. The residual effects of the trend was reduced through polynomial approximation of the high power. It was shown that the spline fitting more efficient. Advantages of the methods for identifying a test signal of small amplitude about of 5 nV was demonstrated. The efficiency of the described methods and advantages of its application to the fluctuation-noise studies have been proven.
