dissolved oxygen and ammonia sensor

Dissolved Oxygen Monitor | Water Quality Monitor

As oxygen diffuses into the active sensor material it interacts with the light absorbing compound and interferes with the emission reaction. This interaction, called quenching, causes the light absorbing material to release energy in a form other than light. The degree of quenching is proportional to the concentration of dissolved oxygen. The quenching reaction is reversible, which allows this ...

Sol-gel based optical sensor for dissolved ammonia ...

Abstract Ormosils were prepared in different ratios of tetramethoxysilane and organically modified sol-gel precursors of type R′Si(OR) 3 and R′ 2 Si(OR) 2 . The pH indicator aminofluorescein was incorporated into various ormosils and the resulting materials were tested for their relative response to pH and dissolved ammonia at constant pH.

Dissolved Ammonia Monitor | Water Quality Monitor

The Q46N Dissolved Ammonia Monitor uses reaction chemistry that converts ammonia in solution to a stable monochloramine compound equivalent in concentration to the original ammonia level. The chloramine concentration is then measured with a unique amperometric sensor that responds linearly to chloramines while eliminating interference from excess free chlorine in solution.

Sensitivity enhancement of ammonia gas sensor based on Ag ...

01/02/2018· Ammonia gas interacts with the chemisorbed oxygen species and it readily oxidizes into N 2, H 2 O and electrons , . The electrons are released into the conduction band resulting in decrease in resistance of gas sensor. The reaction of ammonia with chemisorbed oxygen species can be described as follows: (4) 4 NH 3 + 3 O 2 (ads) − ↔ 2 N 2 + 6 ...

Comparison of Dissolved Oxygen Sensors - pHionics

16/12/2020· Optical Dissolved Oxygen Sensors (ODOs) Optical (also known as luminescent) sensors utilize light to measure dissolved oxygen concentration. Like the electrochemical method, optical ODOs have an oxygen-permeable material at the tip of the electrode. An oxygen-sensitive, luminescent dye makes up the second layer. The dye is exposed to a specific wavelength of light in the sensor and the ...
