Abstract
Description
このような粒子物性測定装置であれば、上述した光学測定用セルと同様の作用効果を得ることができる。
例えば、溶媒のみを収容した光学測定用セル2を保持した第1セルホルダ7と、溶媒及び粒子からなる被検液Xを収容し、光路長が1μmに設定された光学測定用セル2を保持した第2セルホルダ7と、溶媒及び粒子からなる被検液Xを収容し、光路長が3μmに設定された光学測定用セル2を保持した第3セルホルダ7を、スライド部材9上にセットする。その他のセルホルダ7を有するものであってもよい。
そして、第1セルホルダ7の光学測定用セル2を光照射位置に移動させてバックグラウンド測定(透過光測定)を行う。その後、第2セルホルダ7の光学測定用セル2及び第3セルホルダ7の光学測定用セル2を順次光照射位置に移動させて光路長を変えて透過光測定を行う。そして、透過率が85〜90%となる光路長を有する光学測定用セル2を決定し、当該光学測定用セル2を用いて粒子径分布測定を行う。
このように構成した本実施形態の粒子物性測定装置100によれば、一対の透光板21、22における一方の対向面21aにスペーサ膜25を形成しているので、一対の透光板21、22を重ね合わせるだけで所定の光路長を有する光学測定用セル2を構成することができ、光学測定用セル2の組み立てを容易にすることができる。また、対向面21aに一体的に形成されるスペーサ膜25の膜厚により光路長を規定することができるので、別体のスペーサを用いた場合に生じるスペーサの変形や破損を考慮する必要がなく、光路長を短くすることができる。さらに、別体のスペーサを用いないので、光学測定用セル2の組み立て誤差を低減することができ、その結果、粒子径分布測定の前に行う光学測定用セル2に対する光軸合わせを容易にすることができる。その他、スペーサ膜25が第1透光板21に一体的に形成されているので、光学測定用セル2を洗浄する場合にその作業を簡単にすることができる。
なお、本発明は前記実施形態に限られるものではない。

21、22・・・透光板
21a・・・一方の対向面
22a・・・他方の対向面
24・・・反射防止膜
