Micro Pump for Karl Fischer Moisture Analyzers
2025-08-21 23:45:14
As a very important indicator in various industries, moisture has a crucial impact on the quality, taste and shelf life of products. From food to pharmaceuticals, from cosmetics to plastics, it is very necessary to accurately determine the moisture content of products, because the moisture content of products is too high or too low, which will lead to a decline in product quality and an increase in production costs. Therefore, moisture measurement is an essential link in all industries.
The main methods involved in moisture determination include gravimetry, drying method, titration method, refraction method, infrared method and so on.
Different samples need to use different moisture determination methods, for example, solid samples can use the drying method, and liquid samples can use the Kalfaber method.
Karl Fischer moisture tester
In order to solve the problem of moisture measurement, Karl Fischer moisture meter was born. It is a high-precision, efficient and reliable instrument and equipment, which is widely used in food, cosmetics, pharmaceutical and other industries. Karl Fischer moisture measuring instrument adopts the coulometric method, which has the characteristics of fast measurement speed, high precision and simple operation, and has become one of the standard measurement methods in the moisture measuring industry.
Working principles and advantages
Karl Fischer's moisture meter adopts the coulometric method, that is, the electrochemical method to measure moisture. During the measurement process, the sample to be measured is placed in a weighing bottle, the calcium chloride desiccant is added, and the vacuum pump is used to exhaust it, so that it is dehydrated, and finally a completely dry sample is obtained. Then the sample is in contact with the titration solution in the water analyzer. At this time, if the sample contains water, the water will be ionized, forming H and OH- ions. Chemical reactions between the ions will release a certain charge, and the water content in the sample can be calculated according to the number of ions.
Characteristics and advantages
High precision: The measurement accuracy is very high, can reach the accuracy level of 0.001%, can meet the precise requirements of various industries for moisture content.
High efficiency: The use of electrochemical methods to measure the moisture content, the measurement speed is fast, and in a short time to complete a large number of measurement tasks, improve production efficiency.
Easy to operate: The operation is very simple, only need to put the sample to be tested into the instrument, and follow the instructions to complete the measurement, no special skills and knowledge.
High reliability: The use of the coulomb method to measure the moisture content has high reliability and stability, to ensure the accuracy and reliability of the measurement results.
Kamoer KVP04 Vacuum Pump
Kamoer KVP04 vacuum pump, as one of the core components of the Karl Fischer moisture meter, plays an important role. Among them, the function of the KVP04 vacuum pump is to pump the reagent, and the reagent is pressed from the reagent bottle into the titration cup by the positive pressure generated by the vacuum pump. Another KVP04 vacuum pump plays the role of negative pressure to discharge the waste liquid, the waste liquid in the titration cup depends on the negative pressure generated by the air pump in the waste liquid bottle, from the titration cup to inhale the waste liquid bottle (most of the solution is organic reagents, in order to prevent the pump and liquid contact so choose the air pump).
The vacuum pump can quickly and stably extract the gas in the instrument to achieve the required vacuum degree, so as to ensure the accuracy and reliability of the measurement results. The application of the Kamoer KVP04 vacuum pump in the Karl Fischer moisture meter can not only improve the working efficiency and measurement accuracy of the instrument but also reduce the difficulty of the operation and reduce the risk of operating errors. Its use not only saves time and effort but also provides a more reliable and accurate moisture determination technology for food, cosmetics, pharmaceutical, and other industries, ensuring the health and safety of consumers.
