gb/t 5750.5-2023 Standard Test Methods for Drinking Water Part 5: Inorganic Non-metallic Indicators
Nitrite (as n) Diazo-coupled spectrophotometry.
Fully automatic intelligent detection, accurate and efficient
The system saves the standard curves of different ranges of high and low, and can be switched and called arbitrarily as needed.
Automatic sample transfer, automatic addition of reagents, automatic calibration to make standard curves, automatic mixing, automatic dilution of overrange, automatic volume measurement data, automatic cleaning and emptying, and automatic saving of test reports.
The linearity coefficient reaches 0999, the detection data is more accurate.
Friendly human-computer interface One-click operation
Friendly software operation interface, menu-based operation, simplification, one-click operation.
Automatic cleaning of pipelines and collection of waste liquid is safe and environmentally friendly
After the sample analysis, the whole process pipeline is automatically cleaned and emptied.
Experimental waste is automatically collected.
The operation process is completely sealed to avoid contact with toxic and harmful reagents or substances.
How it works
At pH 17 below, nitrite in water is diazotized with p-aminobenzene sulfonamide, and then coupled with n-(1-naphthyl)-ethylenediamine hydrochloride to produce purple-red azo dye, which is colorimetric and quantitative.
Application scenarios
It is suitable for the determination of inorganic non-metallic indicators in drinking water and/or raw water.
It can be used in industries such as water supply, food, and environmental monitoring where nitrite concentration needs to be detected.
