Working principle of ammonia nitrogen water quality online analyzer

2025-08-06

The working principle of the Ammonia nitrogen water quality online analyzer is mainly based on the chemical reaction between ammonia nitrogen and specific reagents, indirectly calculating the concentration of ammonia nitrogen by measuring the color change or potential value change of the reaction product. Here are several common working principles: 1、 Colorimetric method Colorimetric method is the most common detection principle, and its specific steps are as follows: Chemical reaction: In alkaline medium, ammonia nitrogen (in the form of free ammonia or ammonium ions) in water samples reacts with salicylates and hypochlorite ions to form blue compounds (salicylic acid spectrophotometric method), or reacts with Nessler's reagent to form yellow brown complexes (Nessler's reagent spectrophotometric method). Absorbance measurement: By measuring the absorbance at a specific wavelength (such as 697nm or 420nm), the concentration of ammonia nitrogen in water can be indirectly calculated. The absorbance is directly proportional to the ammonia nitrogen content, and the concentration of ammonia nitrogen can be calculated through a pre established calibration curve. 2、 Electrode method The electrode method uses a specific composite electrode to directly measure the ammonia nitrogen content in wa...

What are the maintenance points for digital pH sensors

2025-08-06

1. Regular cleaning Method: Dip a soft cloth or cotton swab in water or specialized cleaning agent, gently wipe the electrode part, and avoid scratching the electrode with hard objects. Attention: Clean the electrodes promptly after measurement to prevent measurement errors caused by the attachment of pollutants (such as algae and oil stains); After cleaning, dry it with filter paper to avoid cross contamination. 2. Calibration management Frequency: Based on the usage scenario, it is recommended to calibrate once a week to once a month; High precision demand scenarios (such as laboratories) require a shorter calibration cycle. Method: Use standard buffer solutions (such as pH 4.01, pH 7.00, pH 10.01) for two-point calibration to ensure sensor response speed and stability. Temperature compensation: before calibration, adjust the temperature compensation setting of the sensor to make it consistent with the temperature of the solution to be measured (the pH value of the standard buffer solution is different at different temperatures). 3. Storage and usage environment Storage: When not in use for a long time, soak the electrode in a 3mol/L KCl solution to avoid drying and electrode aging; The storage environment should be dry, ventilated, and kept away from high temperatures, high humidity, and ...

Working principle of CEMS system

2025-08-06

The working principle of CEMS (Continuous Emission Monitoring System) is based on physical and chemical sensor technology, as well as data acquisition and transmission technology. Through sampling, preprocessing, analysis, data acquisition and transmission, it achieves continuous monitoring of flue gas emissions. The following is a detailed introduction to its working principle: 1、 Sampling and preprocessing Sampling: The CEMS system extracts flue gas samples from the flue through sampling probes. Sampling probes are usually equipped with ceramic or stainless steel filters to filter out dust in flue gas, preventing it from entering subsequent equipment and causing blockage and damage. Preprocessing: The extracted flue gas samples need to undergo pretreatment, including heating, transportation, filtration, and condensation steps. Heating and conveying are used to prevent condensation of water vapor in flue gas and avoid interference with subsequent analysis; Filtering is to further remove particulate matter from the flue gas; Condensation is used to lower the temperature of the flue gas for subsequent analysis. 2、 Gas analysis The preprocessed flue gas sample is sent to a gas analyzer for various component analyses, such as SO ₂, NOx, O ₂, etc. Gas analyzers use various technologies, including b...
