Abstract:
1. A mass analysis data processing method for processing an original spectrum data composed of a one-dimensional array of intensity information collected by a mass analysis, comprising: a compression step, in which a compression process according to a predetermined algorithm is performed on the original spectrum data, and a thereby obtained compressed data composed of a one-dimensional array is stored in a first memory area; an index information creation step, in which index information which links a position in the one-dimensional array of the original spectrum data where a piece of intensity information is present with a position in the one-dimensional array of the compressed data where a piece of compressed information corresponding to the aforementioned piece of intensity information is present is created, and the index information is stored in a second memory area separated from the first memory area; and an information restoration step, in which, when a command for outputting intensity information at a specific position in the one-dimensional array of the original spectrum data is given, a storage position of the necessary compressed information corresponding the aforementioned specific position is recognized by referring to the index information in the second memory area, the necessary compressed information is read from the first memory area, and the read information is decompressed to obtain the intensity information at the aforementioned specific position.
