いたり破壊され、そこから錆が一層広がつて構造
物の腐食が進行しやすい。
Metal structures such as iron bridges and boiler vessels require surface painting on a regular basis to prevent corrosion. However, since salt etc. adhere to the surfaces of these structures, if the surface is painted with a large amount of salt etc. adhering to it, the surface of the structure will rust, the paint film will be lifted or destroyed, and the rust will continue from there. This will further spread the corrosion of the structure.
そこで従来から、構造物の塗装を行なう前に、
構造物表面の付着物の状況を調べ、塩分等の付着
量を測定して、そのまゝ塗装を行なつても良いか
又は構造物表面を洗浄してから塗装すべきかを判

表面から付着物をサンプリングし、分析する方法
に依らなければならない。 Therefore, traditionally, before painting a structure,
The state of the deposits on the surface of the structure is examined and the amount of salt, etc., adhered to is measured to determine whether it is okay to paint as is or whether the surface of the structure should be cleaned before painting. Moreover, since the deposits are scattered on the surface of the structure, the measurement of the deposits must rely on a method of sampling and analyzing the deposits from a fixed area of the surface.
かゝる付着物のサンプリング及び分析測定方法
としては、構造物表面の一定面積の周囲をテープ

測定用電極、比色計、電導度計等を用いて付着物
を分析測定する方法が一般的であつた。 The method for sampling and analyzing such deposits is to mask a certain area of the surface of the structure with tape, etc., wipe the surface surrounded by the tape with clean gauze, etc., and then soak it with a certain amount of water. A common method was to dissolve the deposits by immersing them in an extract solution such as the following, and analyze and measure the deposits using an electrode for measuring ion activity, a colorimeter, a conductivity meter, etc.
しかし、従来の付着物のサンプリング及び分析
測定方法には次に述べるような欠点があつた。 However, the conventional methods for sampling and analyzing deposits have the following drawbacks.
(1) サンプリング操作に非常に多くの時間と手数
を要する。(1) Sampling operations require a large amount of time and effort.
(2) 狭い場所や足場の悪い場所でのサンプリング
操作が極めて困難である。(2) Sampling operations in narrow spaces or places with poor footing are extremely difficult.
(3) サンプリングにガーゼを用いるため、不純物
の付着侵入の防止に慎重を期する必要がある。(3) Since gauze is used for sampling, care must be taken to prevent the adhesion and intrusion of impurities.
(4) サンプリングの手法上、付着物の抽出が難し
く、従つて個人差を生じやすい。(4) Due to the sampling method, it is difficult to extract deposits, and therefore individual differences are likely to occur.
(5) サンプリングと分析測定を別個に別の場所で
行なうので、煩雑である。(5) Sampling and analytical measurements are performed separately at different locations, which is complicated.
本考案は、かゝる従来の事情に鑑み、サンプリ
