An autosampler fora chromatograph includes a sample injector (2), an information inputter (6), a sequence data creator (8) that creates operating instruction sequence data based on an input injecting condition and saves each of an initial injection sequence, a repetitive injection sequence and a duplicate of the repetitive injection sequence in each of a first data region, a second data region and a third data region, a controller (10) that causes the sample injector (2) to execute a successive injecting operation, a sequence changer (12) that changes a duplicate of the repetitive injection sequence in the third data region based on a changed injecting condition when the changed injecting condition in regard to a repetitive injecting operation is input through the information inputter (6), and a sequence re-writer (14) that rewrites the repetitive injection sequence in the second data region with the repetitive injection sequence in the third data region when the repetitive injection sequence is executed repeatedly.
