In modern industry and scientific research, gas leak detection is crucial, especially helium leak monitoring. Helium is often used in superconducting research, aerospace technology, semiconductor manufacturing and other fields due to its special physical properties. Therefore, helium leak detection systems came into being and are different from traditional gas detection systems. In this article today, we will focus on comparing and analyzing the main differences between helium leak detection systems and traditional gas detection systems, and explore their differences in principles, sensitivity, applications, etc.
1. Different detection principles:
Traditional gas detection systems usually use sensors to detect the concentration of a specific gas, and sense the presence of the target gas through chemical reactions or physical changes. These sensors are varied, including electrochemical, catalytic, infrared absorption and other technologies, and are suitable for common gases such as oxygen, carbon dioxide, carbon monoxide, etc. However, the detection of helium faces different challenges. Helium molecules are very small and have stable chemical properties, and are not easy to react with other substances. Therefore, the sensors of traditional gas detection systems are not suitable for helium detection.
Helium leak detection systems usually use specialized technologies such as mass spectrometry, ultrasonic technology, helium calibration, etc. These technologies can accurately detect tiny leaks of helium and provide highly accurate detection results in a short time. Mass spectrometry confirms the presence of gas by detecting changes in the mass spectrum of helium molecules in a vacuum, while ultrasonic technology determines the situation of helium leakage by changes in the sound produced by gas leakage.
2. Sensitivity and specificity:
Helium leak detection systems usually have extremely high sensitivity and specificity. Helium is very light and does not react easily with other gases, so it is difficult for sensors of traditional gas detection systems to detect its tiny leaks. Helium leak detection systems are designed with this characteristic in mind, and are usually able to detect extremely low concentrations of helium leaks, with a sensitivity of ppm (parts per million) or even lower. Traditional gas detection systems are generally less sensitive and difficult to meet the precise detection requirements for trace gases such as helium.
3. Different application scenarios:
Helium leak detection systems are mainly used in automobile industry, semiconductor manufacturing, vacuum systems, superconducting experiments, balloons and gas pipelines. As a rare gas, helium is important in high-tech fields such as ultra-low temperature cooling, gas detection, and aerospace, so the detection requirements for leaks are extremely strict.
Traditional gas detection systems are widely used in industrial production, environmental monitoring, fire protection and other fields, mainly used to detect common harmful gases, such as oxygen, carbon dioxide, carbon monoxide, combustible gases, etc.
4. Cost and technical requirements:
The technical requirements of helium leak detection systems are usually high, and the equipment cost is expensive. Due to the need for special detection technology and high-sensitivity sensors, the price of helium leak detection systems is usually higher than that of traditional gas detection systems. The technology of traditional gas detection systems is relatively mature, the equipment is rich in variety, and the cost is low, which is suitable for conventional gas detection.
5. Safety:
Helium leakage will not only waste precious resources, but also may affect the operation of certain high-precision experiments or equipment. Therefore, helium leak detection systems are very important in terms of safety. Its high precision and high sensitivity can effectively prevent the safety hazards caused by helium leaks. Although traditional gas detection systems can also ensure the detection of gas leaks, they are not as accurate as dedicated systems in the detection of special gases such as helium.
There are significant differences between helium leak detector and traditional gas detection systems in principle, sensitivity and application scenarios. Due to its special physical properties, helium requires the use of specialized technology and equipment for precise detection. Helium leak detection systems usually have higher sensitivity and can accurately detect trace leaks to ensure the safety and stability of high-tech fields. With the continuous development of technology, helium detection systems will play an increasingly important role in all walks of life. Anhui Bowei provides advanced solutions in this field.
