Abstract
【解決手段】本発明の加熱蒸散用吸液芯1は、一方の端部を水性薬剤中に浸漬して吸液させ、他方の端部を加熱して、吸液させた液を蒸散させる加熱蒸散用の吸液芯であって、吸液芯が中空管2の集合体で構成されている。好ましくは、本発明の加熱蒸散用吸液芯1を構成している中空管2がガラス管である。
【選択図】図1
Description
(1)一方の端部を水性薬剤中に浸漬して吸液させ、他方の端部を加熱して、吸液させた液を蒸散させる加熱蒸散用の吸液芯であって、吸液芯が中空管の集合体で構成されていることを特徴とする、加熱蒸散用吸液芯。
(2)前記中空管がガラス管である、(1)に記載の加熱蒸散用吸液芯。
(3)上記(1)または(2)に記載の加熱蒸散用吸液芯の一方の端部を水性薬剤中に浸漬して吸液させ、他方の端部を加熱して、吸液させた液を蒸散させる、水性薬剤の加熱蒸散方法。
式中、Tは液体の表面張力(N/m)を表し、ρは液体の密度(kg/m3)を表し、gは重力加速度(m/s2)を表す。
図1に示すように、ガラス製の中空管(長さ64mm、内径0.63mm)を32本束ねて支持体を用いて略円柱状に固定し、加熱蒸散用吸液芯を得た。ガラス製の中空管としては、表1に示すように、ドラモンド社製のマイクロキャップス20μLを使用した。この吸液芯を用いて蒸散試験を行った。蒸散試験には、下記に示す成分を各0.4g混合し、精製水を加えて100gとした水性薬剤(メトフルトリン濃度0.4質量%)を使用した。
<成分>
メトフルトリン
ポリエチレングリコール(40)水添ヒマシ油(エマノーンCH40(花王(株)製))
モノオレイン酸ポリオキシエチレンソルビタン(6E.O.)(レオドールTWO106(花王(株)製))
図3に示す加熱蒸散装置を用いて蒸散試験を行った。薬剤容器4に上記のメトフルトリンを含む水性薬剤を入れ、吸液芯1としては、上記のガラス製の中空管を束ねて得られた加熱蒸散用吸液芯を用いた。
蒸散効率(%)=(有効成分量(mg)/理論有効成分量(mg))×100 (I)
理論有効成分量(mg)=液量(mg)×0.4%(メトフルトリン濃度) (II)
蒸散効率の変動(%)=(B/A)×100 (III)
A:6〜8時間後の2時間の蒸散効率。
B:168〜170時間後の2時間の蒸散効率。
吸液芯1にかえて表1に示す吸液芯を用いた以外は、実施例1と同様の手順で有効成分量を測定し、蒸散した液量および捕集された有効成分量から蒸散効率を求め、得られた蒸散効率から蒸散効率の変動を求めた。その結果を表2に示す。
2 中空管
3 支持体
4 薬剤容器
5 収納容器
6 加熱手段
Claims (3)
- 一方の端部を水性薬剤中に浸漬して吸液させ、他方の端部を加熱して、吸液させた液を蒸散させる加熱蒸散用の吸液芯であって、
吸液芯が中空管の集合体で構成されていることを特徴とする、加熱蒸散用吸液芯。 - 前記中空管がガラス管である、請求項1に記載の加熱蒸散用吸液芯。
- 請求項1または2に記載の加熱蒸散用吸液芯の一方の端部を水性薬剤中に浸漬して吸液させ、他方の端部を加熱して、吸液させた液を蒸散させる、水性薬剤の加熱蒸散方法。
