Ammonia Nitrogen Analyzers: High - Precision Detection Based on Spectrophotometry for Water Quality Safety

Ammonia nitrogen is one of the important indicators for water quality testing, and excessive concentration can cause harm to the ecological environment and human health. As a professional water quality analysis equipment, the ammonia nitrogen analyzer can quickly and accurately detect the ammonia nitrogen content in water bodies.

Detection principle and method of ammonia nitrogen analyzer

The ammonia nitrogen analyzer is mainly based on spectrophotometry for detection, with multiple built-in light sources that can adapt to different detection methods:

1. Nessler's reagent method (HJ 535-2009):

Suitable for relatively clean water bodies, with a wide detection range (0.02~50mg/L)

Principle: Ammonia nitrogen reacts with Nessler's reagent to form a yellow brown complex, and the absorbance is measured at a wavelength of 420nm.

2. Salicylic acid method (HJ 536-2009):

Suitable for complex water quality (such as industrial wastewater), with strong anti-interference ability

Principle: Ammonia nitrogen reacts with salicylic acid to form a blue compound, which is detected at a wavelength of 697nm

Both methods comply with national environmental standards, and users can choose the appropriate testing plan based on the characteristics of water quality.

Characteristics of ammonia nitrogen analyzer

Modern ammonia nitrogen analyzers not only have high-precision detection capabilities, but also incorporate intelligent design:

High definition touch screen: Android intelligent operating system, Chinese display interface, Chinese and English keyboards, intuitive operation;

Intelligent data analysis: supports chart and list display, convenient data export, supports WIFI, RJ45, mobile hotspot network transmission, and detection data can also be exported through USB flash drive;

Multi functional sample management, capable of naming samples in both Chinese and English, facilitating sample recording and data storage;

Data storage and transmission: Store 8 million sets of data, which can be searched through time for easy access to large amounts of data; With a supervision cloud platform, data can be uploaded through the LAN and the Internet.

These functions make the ammonia nitrogen analyzer suitable for various scenarios such as laboratories, sewage treatment plants, environmental monitoring stations, etc.

Application fields of ammonia nitrogen analyzer

Ammonia nitrogen analyzer is widely used for the detection of various types of water bodies, including:

Industrial wastewater: monitoring of high ammonia nitrogen wastewater in the chemical, petroleum, and coking industries; Control of discharge water quality in papermaking and metallurgical enterprises

Municipal sewage: ammonia nitrogen detection of inlet and outlet water of sewage treatment plants; Evaluation of the effectiveness of urban black and odorous water treatment

Natural water body: surface water monitoring of Rivers and Lakes; Protection of drinking water sources

Research and environmental law enforcement: environmental investigation, pollution tracing; Compliance inspection of enterprise emissions

Whether it is high concentration industrial wastewater or low concentration surface water, the ammonia nitrogen analyzer can provide reliable detection data.

The ammonia nitrogen analyzer has become an important tool for water quality monitoring due to its high precision, intelligence, and wide applicability. Users can choose between Nessler's reagent method or salicylic acid method based on water quality characteristics when selecting detection methods to ensure data accuracy.
