- 先端に吸入吐出口をもつ筒状のシリンジ内でピストンが前記シリンジの軸方向に動作させられるシリンジポンプ、試料の酸化処理を行なうためのリアクタ、前記試料の光学的測定を行なうための測定部、及び前記シリンジポンプの動作を制御するための制御装置を備え、前記シリンジポンプにより吸入した液を前記リアクタ及び前記測定部へ送液するように構成された水質分析計であって、
前記水質分析計は、
前記吸入吐出口から吸入された液相が互いの間の空間を通過することによって互いの間の静電容量が一時的に変化するように前記シリンジの先端側に前記シリンジの前記軸方向に互いに間隔をもって設けられた一対の電極と、
前記一対の電極間の静電容量の値、又は前記静電容量の変化に伴って変化する値に基づく検出信号を出力する検出部と、を備えており、
前記制御装置は、前記シリンジポンプに液を吸入させた後で空気を吸入させる際に、前記検出部により出力される前記検出信号のピークが現れたときに、前記シリンジポンプによる液の吸入が行われたことを検出するように構成された液吸入検出部を有し、前記シリンジポンプに液を吸入させるタイミングで前記検出部の検出信号を読み取って前記液吸入検出部に前記シリンジポンプによる液の吸入が行われたか否かを検出させ、それによって、前記シリンジポンプによる液の吸入にエラーが発生しているか否かを検知するように構成されている、水質分析計。 - 前記一対の電極は、前記シリンジの外周面の2箇所に巻き付けられたアルミニウム薄膜を備えている、請求項1に記載の水質分析計。
