Claims (5)
- 被計測液を導入する導入口を一端に有するとともに他端を外気に導通させてなる流路と、
その流路上に設けた前記被計測液の計測に用いる第1の検出部と、
前記流路上における第1の検出部よりも他端に近い所定位置に前記被計測液が到達したことを検出する第2の検出部と、を備えており、
前記第2の検出部が、前記第1の検出部から当該第2の検出部までの流路の容積が予め定めた一定容量となる位置に設けられ、
さらに前記第2の検出部が、前記流路の他端の開口部から当該第2の検出部までの流路の容積が前記被計測液の供給停止の遅れを考慮した容量以上となる位置に設けられていることを特徴とする測定装置。 - 前記各検出部からの電気的出力信号を受信して、分析演算処理を行う計測部本体と、
前記流路及び各検出部を内部に有するとともに、前記各検出部の電極の一端部を流路外部に表出させてなり、その電極一端部において前記計測部本体に着脱可能に接続されるカートリッジと、を備えていることを特徴とする請求項1記載の測定装置。 - 前記被計測液が粒子を含む電解液からなるものであり、
前記第1の検出部が、流路上に設けたアパーチャ部と、同流路上であって前記アパーチャ部を挟む位置に配置された一対の計測用電極とからなるものであり、
前記一対の計測用電極間に生じる電気抵抗の変化に基づいて前記アパーチャ部を通過する粒子数を計測可能に構成し、前記第1の検出部から下流側において2分岐し、その分岐された流路より下流側に前記第2の検出部を一対設けている請求項1または2記載の測定装置。 - 前記第1の検出部が、被計測液自身の発光または外部光を照射されることによる透過光、反射散乱光、蛍光を透過する、流路壁に形成した窓を有してなるものである請求項1、2または3記載の測定装置。
- 前記第2の検出部が、流路内壁に設けられ、被計測液に接触してそれが到達したことを検出するものである請求項1、2、3または4記載の測定装置
