Title:
特に硝酸度を測定するために用いられる、有色インディケータを含む、光ファイバ化学センサの製造
Document Type and Number:
Japanese Patent JP4805526
Kind Code:
B2
Abstract:
The invention concerns the production of a chemical sensor which can be used to measure nitric acidity.This sensor is produced using a sol-gel method for depositing a porous film, containing a colored indicator, on the core of an optic fiber. The pH of the initial sol is adjusted as are other conditions for implementing the sol-gel method to obtain stability of the signal (curves 1 to 4) emitted by the sensor in an 8N nitric medium for at least 1000 hours.
