Provided is an analyzer performing solid-phase extraction of a measurement component (i.e., component to be measured) in a sample solution while decreasing an amount of waste generated and reducing a running cost. The analyzer includes: a solid-phase extraction container having a body part to receive a sample solution containing a measurement component of analytical target and a discharge passage to discharge the sample solution. Herein, the discharge passage is to be filled with a solid-phase extraction material for subjecting the measurement component to solid-phase extraction. The analyzer further includes a supplying mechanism for a solid-phase extraction material; a filter supplying mechanism; a determining mechanism for filling position; a discharging mechanism for discharging the filter and the solid-phase extraction material after the solid-phase extraction of the measurement component; and a container cleaning mechanism for cleaning the solid-phase extraction container from which the solid-phase extraction material is removed.
