プルの漏れのおそれがあった。When inspecting or cleaning the measuring cell 1, the measuring cell 1 is pulled out downward in the figure. First, with the measuring cell 1 placed inside the case 5, the connecting portion 14 of the upper outflow pipe 3 is pulled out.
It was necessary to remove the external conduit 7 from the tube and then pass through the case, and there was a risk that the sample would leak into the case 5, as in the case of FIG.
この考案は、これらの不都合を解消し、点検や洗浄に際
して測定セルのケースよりの着脱作業が容易で、かつケ
ース５内への漏れのおそれがない連続光吸収分析計を提
供せんとするものである。This invention aims to eliminate these inconveniences and provide a continuous light absorption analyzer in which the measurement cell can be easily attached and removed from the case during inspection and cleaning, and there is no risk of leakage into the case. be.
第３図は、この考案の一実施例を示す連続光吸収分析計
の縦断面図で、第１図、第２図と共通の部分には同一の
符号が付しである。FIG. 3 is a longitudinal sectional view of a continuous light absorption analyzer showing an embodiment of this invention, and parts common to those in FIGS. 1 and 2 are given the same reference numerals.
図において、セル室１５の片面にはケース５の外面に測
定セル１を取付けることができるようにセル室１５の外
形寸法より大きく、且つケース１に形成された後述の開
口を閉塞するにたる寸法の縁が設けている。In the figure, one side of the cell chamber 15 has a dimension larger than the outer dimensions of the cell chamber 15 so that the measurement cell 1 can be attached to the outer surface of the case 5, and a dimension that is large enough to close an opening formed in the case 1, which will be described later. There is a rim.
またケース１の光源部８と測光部９との間の下面壁には
測定セル１をケース１内に挿入するための開口が形成さ
れている。Further, an opening for inserting the measurement cell 1 into the case 1 is formed in the lower wall between the light source section 8 and the photometry section 9 of the case 1 .
したがって測定セル１を前記開口よりケース５内に挿入
すると、開口は縁で閉塞されこの縁を介して、小ねじ等
で測定セル１をケース１に対し着脱可能に取付けること
ができる。Therefore, when the measuring cell 1 is inserted into the case 5 through the opening, the opening is closed by the edge, and the measuring cell 1 can be removably attached to the case 1 using machine screws or the like via this edge.
さらにこの壁面には流入管路１２と流出管路１３が設け
てあり、セル室１５内には第４図の縦断面図のようにセ
ル窓１０の間をサンプルが通過するように隔壁１７が設
けである。Further, an inflow pipe line 12 and an outflow pipe line 13 are provided on this wall surface, and a partition wall 17 is provided in the cell chamber 15 so that the sample passes between the cell windows 10 as shown in the longitudinal cross-sectional view of FIG. It is a provision.
外部管路７は可撓性管材が用いてあり、測定セル１の点
検や洗浄にあたっては、外部管路７を接続したままで、
ケース５から測定セル１が引きだせるので、ケース５内
でサンプルが漏出するおそれは全くない。The external pipe line 7 is made of flexible pipe material, and when inspecting or cleaning the measuring cell 1, leave the external pipe line 7 connected.
Since the measurement cell 1 can be pulled out from the case 5, there is no risk of the sample leaking inside the case 5.
なお、ケース５の一方側端面たとえば下面から測定セル
１を挿入する方式であるので、予めサンプルを排出して
外部管路との接続を解放すれば、ケース５内のサンプル
漏出を心配せずに測定セル１をケース５から取りだすこ
とができる。Note that since the measurement cell 1 is inserted from one side end surface of the case 5, for example, from the bottom surface, there is no need to worry about sample leakage inside the case 5 if the sample is discharged in advance and the connection with the external pipe line is released. The measuring cell 1 can be taken out from the case 5.
第５図は、この考案の他の実施例の縦断面図で、図のよ
うにセル室１５内に隔壁を設けないで、流出管路１８を
セル室１５の先端部迄延長した構造にすれば前記実施例
と同様の効果が期待できる。FIG. 5 is a longitudinal cross-sectional view of another embodiment of this invention, in which a partition wall is not provided in the cell chamber 15 as shown in the figure, and the outflow pipe 18 is extended to the tip of the cell chamber 15. In this case, the same effects as in the above embodiment can be expected.
この考案は以上のように、点検や洗浄のために測定セル

ルを取り出すことができるもので、その実用的効果は頗
る大なるものである。As described above, this invention eliminates the need to connect and disconnect pipe connections within the case when taking the measurement cell out of the case for inspection or cleaning, and also prevents the removed pipes from passing through the case. Therefore, there is no risk of the sample leaking into the case, and the measurement cell can be taken out from the case with a simple operation, and its practical effects are extremely large.
