Description
図1は、実施の形態の検査装置1の構成を模式的に示す図である。検査装置1は、水系試料2を検査するための装置である。図1を参照して、検査装置1は、分離装置100とTOC装置200(測定部)とを備える。検査装置1は、分離装置100によって水系試料2中の物質を大きさに応じて分離し、大きさに応じた順で分離装置100から溶出される各物質を酸化させ、各物質に含まれる有機炭素の量(TOC量)をTOC装置200によって測定する。これにより、検査装置1は、大きさの異なる水系試料2中の溶存有機物ごとにTOC量を測定する。
図2は、分離装置100および前処理部220の構成を模式的に示す図である。本実施の形態において、溶離液は、純水とリン酸緩衝溶液とを別々のポンプで送液し、流路F内で混合させることで生成される。
図3は、酸化部242の構成を模式的に示す図である。酸化部242は、添加部422と、照射部424とを備える。添加部422は、酸化部242の入り口に設けられている。照射部424は、添加部422の下流に設けられている。
図4は、変形例にかかる検査装置1aの構成を模式的に示す図である。上記実施の形態において、検査装置1は、測定装置として、TOC装置200だけを備えている。なお、検査装置1は、TOC装置200に加えて他の測定装置を備えていてもよい。変形例にかかる検査装置1aは、TOC装置200に加えて、紫外可視分光光度計12および蛍光光度計14をさらに備える点で上記実施の形態に示した検査装置1と異なる。
上述した複数の例示的な実施形態は、以下の態様の具体例であることが当業者により理解される。
(第3項)第1項または第2項の検査装置は、保温部と容器を収容するカラムオーブンをさらに備える。
