Helium mass spectrometer leak detector technology is widely used in vacuum equipment, airtightness testing and other fields with its high sensitivity and high precision. As the complexity of industrial equipment increases, it becomes particularly important to use helium mass spectrometers for effective leak detector. In order to ensure that the helium mass spectrometer can accurately and efficiently complete the leak detector task, it is crucial to master some operating skills and precautions. Today, our berth experts will focus on introducing several key operating tips that need to be paid attention to during the use of helium mass spectrometer leak detector.
1. Correctly select the detector mode
Helium mass spectrometers usually provide different detector modes, including quantitative detector and qualitative detector. Before operation, the appropriate mode should be selected according to the type of detector object, the possibility of leakage and the required sensitivity. For example, for the overall leak detector of large equipment, a lower sensitivity mode can be selected; for small leaks of precision equipment, a high sensitivity mode is required.
2. Check the equipment status and calibration
Before using the helium mass leak spectrometer, you must ensure that the instrument is in normal working condition. First, check whether the helium supply is sufficient, whether the vacuum system of the mass spectrometer is normal, and whether the power supply and connection are stable. Then calibrate the instrument to ensure measurement accuracy. Regular calibration is the key to improving leak detector accuracy and reliability.
3. Strictly control environmental conditions
Helium mass spectrometers are very sensitive, and the surrounding environment may affect the test results. When performing leak detector operations, try to avoid air flow, vibration or temperature fluctuations around the equipment, as these factors may cause detector errors. Ensure that the test environment is quiet and stable, and it is best to operate in an environment with controlled temperature and humidity.
4. Keep the leak detector area sealed
When using a helium mass spectrometer for leak detector, ensure that the area to be detected is completely sealed to avoid leakage of external air or helium affecting the results. If the pipes or interfaces around the leak source are not completely sealed, helium may leak to other locations, affecting the accuracy of the test results.
5. Choose the right probe and detector position
The probe of the helium mass spectrometer should be selected according to the shape and structure of the object to be detected. The probe should be placed as close to the leak source as possible to avoid detector that is too far or at an incorrect angle. For complex pipes or equipment, the probe should cover multiple areas where leakage may occur to ensure comprehensive detector.
6. Regular cleaning and maintenance
During long-term use, helium mass spectrometers may accumulate dust or other dirt, affecting their measurement accuracy. Regular cleaning of the probe and various parts of the instrument, especially the sensor and detector pipeline, is the key to maintaining the performance of the instrument. At the same time, regular maintenance and overhaul of the equipment should be performed to ensure that the helium mass spectrometer is always in the best working condition.
7. Avoid excessive operation and operating errors
When operating a helium mass spectrometer, avoid frequent adjustment of equipment parameters or excessive operation of the instrument, especially during the detector process, frequent changes in the detector mode or probe position will lead to unstable measurement results. In addition, operators should be familiar with the operating manual and precautions of the equipment to avoid equipment damage or detector failure due to operating errors.
The correct use of a helium mass spectrometer for leak detector requires operators to have certain experience and skills. From equipment selection and calibration to environmental control and equipment maintenance, every detail may affect the final test results. Only by ensuring that all operations are properly performed can the detector efficiency of the helium mass spectrometer be improved and the safety and reliability of the equipment and system be ensured. By continuously accumulating experience, operators can achieve more accurate results in leak detector.
