<P>PROBLEM TO BE SOLVED: To provide an analyzer with which a measurement impossible state due to clogging of a flow channel is automatically avoided in the analyzer with the flow channel for sending solution of a sample. <P>SOLUTION: An analyzer includes: an eluant sending part which sends eluant; a sample introduction part which is provided on an eluant flow channel; a separation column which is connected with the sample introduction part via a flow channel; a switching means which is provided between the sample introduction part and the separation column for dividing the flow channel between the sample introduction part and the separation column into first and second flow channels; first and second filters which are provided on the first and second flow channels, respectively; a cleaning solution flow channel through which cleaning solution for cleaning the first or second filter passes; a cleaning solution sending part which sends the cleaning solution; and a discharge flow channel which is connected with the cleaning solution flow channel via the first and second flow channels, and to which the cleaning solution with which the first and second filters are cleaned is discharged. <P>COPYRIGHT: (C)2012,JPO&INPIT |
