Summary:To detect machine abnormality of an analyzer in a simple configuration.SOLUTION: An analysis system comprises: an analyzer having a probe for sucking and discharging liquid, a plunger 114 connected to the probe via a dispensing channel T, a vertical rotation operation unit 112 that moves the position of the probe, and a pressure sensor P that is provided at a position closer to the plunger 114 than a portion that moves integrally with the probe by the vertical rotation operation unit 112 in the middle of the dispensing channel T connecting the probe and the plunger 114, and in the dispensing channel T, and detects the pressure of the liquid in the dispensing channel T; and an abnormality determination unit 203 that analyzes the presence or absence of abnormality for the operation that was performed at the timing when the pressure data was acquired, based on the pressure data detected by the pressure sensor P.SELECTED DRAWING: Figure 2 【課題】簡便な構成で分析装置の機械異常を検出することを課題とする。【解決手段】液体を吸引及び吐出するプローブと、プローブと、分注流路Tを介して接続するプランジャ114と、プローブの位置を移動させる上下回転動作部112と、プローブと、プランジャ114とを結ぶ分注流路Tの途中、かつ、分注流路Tにおいて、上下回転動作部112によりプローブと一体となって移動する部分よりもプランジャ114に近い位置に設けられており、分注流路T内の液体の圧力を検知する圧力センサPと、を有する分析装置と、圧力センサPで検知された圧力データに基づいて、圧力データを取得したタイミングで行われていた動作について、異常の有無についての解析を行う異常判定部203と、を有することを特徴とする。【選択図】図2
