Abstract

　本発明は、エンドトキシンやβ－Ｄグルカンなど、ゲル化反応により測定される物質の濃度を、短時間で正確に測定できるようにすることを課題とする。ゲル化反応によって試料中の目的物質を測定する測定装置において、測定目的の物質を含む検体とゲル化を生じる試薬を含む溶液を収容する試料セル１３に対して、発光ダイオード１４の照明光を照射する。試料セル１３中の溶液は、攪拌棒２５により攪拌され微小かつ均一なゲル粒子を生成させ、照明光中を通過させる。試料セル１３中で生成するゲル粒子の透過光をダイオード２２で検出し、その透過光検出出力に基づき、コンピュータ２１により一定以下の透過光量が検出されるまでの遅延時間に基づき、前記溶液中の前記物質の濃度を測定する。
