質の担体な球状にすることにより、計数時に誤認するこ
とかない。Porous carriers tend to absorb organic substances on their surfaces, and carriers that have adsorbed phosphorus particles emit light when irradiated with ultraviolet rays. Therefore, by contaminating the object to be cleaned as carrier contaminants and counting the number of foreign objects before and after cleaning while irradiating ultraviolet rays, it is possible to distinguish them from foreign objects that have contaminated the object to be cleaned for some reason during the counting process. Can be done. In addition, by making the carrier spherical and porous, there will be no misidentification during counting.
以下、本発明の一実施例を図面を用いて説明する。第1
図は洗浄効果の評価を行う方法を示す。An embodiment of the present invention will be described below with reference to the drawings. 1st
The figure shows how to evaluate cleaning effectiveness.
第2図は叶い覚剤を表面の多孔質に吸着させた担体な示
し、第3図は全多孔1に吸着させた担体を示す・
先ず、第1図において、けい覚剤を吸着させた球状担体
1を汚染物として被洗浄体2に汚染させ。Figure 2 shows a carrier with a stimulant adsorbed to its porous surface, and Figure 3 shows a carrier with all pores adsorbed. The carrier 1 is used as a contaminant to contaminate the object 2 to be cleaned.
紫外線を被洗浄体2に照射する。被洗浄体2上の球状担
体1は紫外線を吸収してけい光を発光する。The object to be cleaned 2 is irradiated with ultraviolet light. The spherical carrier 1 on the object 2 to be cleaned absorbs ultraviolet rays and emits fluorescent light.
球状担体1から発大したけい光は検出器3で検出し計数

洗浄後の被洗浄体2上の担体1を前記と同様に紫外線を
照射し洗浄でとりきれなかった担体1を計数する。この
様に、叶い覚剤を吸着させた球状担体を汚染物として洗
浄前後の数を計数することにより洗浄評価が行える。The fluorescent light emitted from the spherical carrier 1 is detected by a detector 3 and counted by a counting device %4. Next, for example, ultrasonic cleaning is performed, and the carriers 1 on the cleaned object 2 are irradiated with ultraviolet rays in the same manner as described above, and the carriers 1 that cannot be removed by the cleaning are counted. In this way, cleaning evaluation can be performed by counting the number of spherical carriers adsorbed with stimulants as contaminants before and after cleaning.

染物として上記方法で洗浄効果の評価を行うことにより
異物計数作業中に汚染する異物と区別できる効果がある
。As mentioned above, by evaluating the cleaning effect using the above method as a contaminant by adsorbing the stimulant on a porous spherical carrier, it is possible to distinguish it from foreign matter that contaminates during the foreign matter counting operation.
本発明によれば、異物計数中に何らかの原因で外部から
汚染した異物と洗浄で落しきれなかった異物と区別でき
るので正確な洗浄効果の評価ができる。According to the present invention, since it is possible to distinguish between foreign matter that has been contaminated from the outside for some reason and foreign matter that cannot be completely removed by cleaning during foreign matter counting, it is possible to accurately evaluate the cleaning effect.
