First analysis information including at least one of a sample analysis condition, a sample preparation condition and a kind of sample is assigned to at least one kind of jig, and the jig is arrangeable to correspond to any of a plurality of sample holders. Holding information representing whether a sample is held by each sample holder and jig information for identifying the kind of jig are acquired by a first information acquirer from an automatic sample injector. The first analysis information in regard to a corresponding sample holder is specified by a first analysis information specifier based on jig information. A batch file for controlling a sequence of analysis or preparation in regard to a sample held by a sample holder corresponding to a jig is created by a batch file creator with use of the holding information and the first analysis information.
