An absorption start point of a substance to be absorbed is set in pieces of the time-series data. An editor combines and displays at least frequency variation regions in the data. The absorption start point setting is realized when an operator positions a pointer and clicks on the time-series data, or when an absorption start signal is output at the time when a solution is supplied.
