PH electrode is a commonly used sensor for water quality analyzers, and PH electrode is also one of the parts that simply have problems in daily testing. We have told us before that we must pay special attention to it whether it is used, stored, and cleaned. But as a commonly used wearable part, the correct maintenance method can only extend the service time of the PH electrode. In order to ensure the accuracy of the water quality analyzer, the PH electrode must be replaced in the end. We must pay attention to the following factors when buying PH electrodes.

The raw material of the electrode

We all know that the raw materials of the PH electrode can be divided into two types. One is the PH electrode of glass raw material. The PH electrode of glass raw material has a wide temperature measurement scale and can detect corrosive materials and solvents. It is relatively simple to crack, and special attention should be paid when cleaning. The other is the PH electrode made of plastic materials. The big advantage of this PH electrode is that it is easy to clean and has strong durability. However, it is weaker than glass raw materials in terms of applicable scale.

The structure of the electrode

Common PH electrodes can be divided into two structures: liquid electrolyte, gel, and polymer. The PH electrode with liquid electrolyte structure is commonly used in water quality analyzers. The PH electrode with a liquid electrolyte structure can be used to make up or replace it. For example, when the electrolyte is found to be contaminated, it can be dealt with by replacing the electrolyte. Therefore, the PH electrode of the liquid electrolyte structure has a longer service life, but it is under measurement. The gel-structured PH electrode uses gel or polymer. The protection of the PH electrode of this material is relatively simple, and will not be interfered with by external ions, and will not be affected by changes in external pressure.

The primary detection target of the electrode

General specification PH electrode can use various test items, but it is not applied to all test samples. We all know that the water quality analyzer is mainly for analyzing and testing water bodies, but it can also detect data from a variety of solutions. And some solutions will form errors when using standard PH electrodes to detect. Common ones are some semi-solids, solids, or solids suspended in solution samples. When testing the pH value of these solutions, testers generally choose a special-style PH electrode, such as a conical-sensing PH electrode.

The water quality analyzer is a rare water quality monitoring instrument that can accurately determine whether the water quality is polluted. But at the same time, there are many unfavorable factors that want to affect the monitoring data of the water quality analyzer, such as the fully enclosed system, the accuracy of sampling, the speed of magnetic mixing, etc., but in practice, if the water quality online monitor can be used in a targeted and correct manner, It can still effectively improve the accuracy of instrument monitoring, make its data representative, and at the same time, it can also complete the long-term effective and stable operation of the water quality analyzer system.

1. The system is fully enclosed

The connection of the Karl Fischer reagent liquid path must be fastened, from the reagent bottle to the metering pump to the reaction tank, otherwise, reagent leakage will directly affect the test results. Another problem with its non-sealing is that the Karl Fischer reagent absorbs air moisture during the test, which will cause the end of the titration to be delayed.

2. The precise problem of sampling

When calibrating the Karl Fischer reagent, you need to take 10mg of water. Try to use a 10ul sampler. This is not only accurate and fast but also prevents the adhesion of water droplets. Similarly, the use of methanol reagents and ethyl esters also have similar problems. After the handling is completed, attention should be paid to shorten the time when the reaction cell is opened as much as possible.

3. Magnetic mixing speed adjustment

In the reverberation cell, because the titration reagent is in the part when it is added, it is not in the same place as the electrode, so the mixing speed is so fast that no turbulence is formed so that it can reach the end soon.

4. The system is as tight as possible

The manual moisture analyzer needs to add a U-shaped tube filled with desiccant to the top of the suction bulb pipe and the glass burette to reduce the disturbance of air moisture to the test results. In an environment where the relative humidity of the air is greater than 70%, the moisture test should not be arranged as much as possible.

5. The titration speed setting should be fast and then slow. The titration is fast at first to shorten the experiment time as much as possible, and the strain is slow towards the end, which can improve the meter measurement.

6. The water quality analyzer should be far away from the strong magnetic field to prevent the electrons from appearing to be bounced and abnormal during operation. For manual moisture analyzers, it is necessary to use a glass automatic burette to measure Karl Fischer reagent and methanol solvent, and the glass burette itself needs to be connected to the outside due to the equilibrium pressure.

7. When adjusting the titration speed of the burette, adjust it to 1 drop/sec. Too fast a titration speed will result in a larger delay error when the end is reached; while a too slow titration speed will prolong the test process, and the above-mentioned disturbances will easily lead to delays in reaching the end.

8. After the experiment on the same day, the Karl Fischer reagent in the system must be drained, and then cleaned with methanol. Never clean the system with water. Because it is not easy to volatilize, it will cause the Karl-Fischer reagent in the next experiment. The Fischer reagent is not calibrated correctly.

The Impacts of Climate Change on Water Quality and How Analyzers Help

Climate change is a global phenomenon, and its impact has far-reaching effects on the environment and human health. One of the most significant impacts of climate change is its effect on water quality. Climate change can cause changes in precipitation patterns, temperature, and weather patterns, which can all affect water quality. Analyzers are essential tools that can help in monitoring water quality, and they are effective in detecting harmful contaminants in water. This article outlines the impacts of climate change on water quality and how analyzers can help in ensuring the safety of our water resources.

The Impacts of Climate Change on Water Quality

Climate change can affect water quality in several ways. Temperature changes can lead to an increase in water temperature, which can have impacts on the water chemistry and its biological quality. High water temperatures can promote the growth of harmful algae, which can cause health problems. Increased precipitation can also cause water pollution by washing pollutants from the land into water bodies. Thus, flooding becomes a more significant problem, and it can cause massive damage to the natural environment and human infrastructure.

Extreme weather events, such as hurricanes and cyclones, can also affect water quality. These events can lead to sewage overflows, which can pose significant health risks, especially to vulnerable communities. Stormwater runoff can carry pollution such as bacteria or sediment from the land into water bodies creating hazardous and unsafe water for human consumption.

Not only that, but climate change also has an impact on water resources and supply. Droughts become more common, which can lead to water scarcity, and water sources become overused, which can affect water quality and its reliability as a safe source of drinking water.

Analyzers: Essential Tools in Monitoring Water Quality

Analyzers are essential tools used for detecting water quality issues and identifying harmful substances in water sources. They are effective in detecting contamination from pesticides, heavy metals, bacteria, and other pollutants. Additionally, analyzers are equipped with technology that helps monitor changes in water chemistry and temperature that can help detect potential water concerns before they become a major problem.

Analyzers come with various measuring technologies, each designed to detect specific contaminants. Some analyzers detect the organic and inorganic pollutants caused by industrial and agricultural activities. These contaminants can include nutrients like phosphates and nitrates, which contribute to the growth of harmful algal blooms.

Other analyzers are designed to detect heavy metals like cadmium, copper, and lead that are prevalent in groundwater. These contaminants cause water to have taste, odor, and color issues. Presence of these harmful substances can also pose severe health risks to vulnerable communities.

Analyzers can detect changes in pH, temperature, and other water quality parameters that are important indicators of water quality issues. Equipment like turbidity meters and conductivity meters are essential tools in detecting changes in water quality, and they allow early detection of potential issues.

Conclusion

Climate change is causing significant impacts on water resources, and it is impacting water quality. Increased temperatures, unpredictable weather patterns, and changes in precipitation all contribute to the contamination of water resources. Analyzers are essential tools in detecting contaminants and identifying potential issues in water quality. They are equipped with technology like pH monitors, turbidity meters, and other sensors to detect changes in water quality indicators. Analyzers are vital tools in ensuring our water resources remain safe and sustainable.
