In many fields such as industrial production and scientific research, the detection of sealing is crucial. Whether it is the strict requirements for vacuum environment in aerospace equipment or the need to prevent the intrusion of tiny impurities in the electronic semiconductor industry, it is inseparable from a magical detection instrument - كاشف تسرب مطياف كتلة الهيليوم. Today, let us explore the working principle of helium mass spectrometer leak detector and unveil its secret of accurate leakage detection.

1.Basics of Mass Spectrometry

Mass spectrometry is an analytical method for measuring the mass-to-charge ratio (mass-to-charge ratio) of ions, and is the core technical means of helium mass spectrometer leak detectors. The basic principle is to ionize the components in the sample into charged ions in the ion source, and then use the accelerating electric and magnetic fields to form an ion beam, which enters the mass spectrometer chamber to separate and detect these ions. Ions of different masses will move along different trajectories in the electric and magnetic fields. By measuring the mass-to-charge ratio (m/z) of the ions and their relative abundance, the composition and structure of the substance can be determined. This is like being in a huge ion "sorting factory", where each ion is precisely assigned to a specific "channel" according to its own "weight" and "charge", so that it can be identified.

2.Unique Advantages of Helium

Why does the helium leak detector choose helium (chemical formula: He) as the tracer gas for leak detection? This is because helium has a series of excellent properties.

First, the chemical properties are stable: Helium is an inert gas with extremely stable chemical properties. It hardly reacts chemically with other substances, which ensures that it will not affect the object or system being tested during the detection process.

Third, easy to detect: Helium has good diffusivity. Once a leak occurs in the detected object, it can diffuse evenly and quickly, accelerating detection and quickly discovering tiny leaks. Its content in the air is extremely low, and its volume content in the atmosphere is about 1/52000. Once a leak occurs, helium can be easily detected by a helium mass spectrometer leak detector because its mass spectrum peak is very sharp and easy to identify, and will not be confused with other gases.

Fourth, non-toxic: Helium is a colorless, odorless, non-toxic gas that is harmless to the human body and the environment and can be used safely in many environments.

Fifth, non-flammable: Helium is non-flammable and is not likely to cause fire or explosion. It is suitable for use in flammable, explosive, high temperature and high pressure environments.

Sixth, economical: Although helium is relatively expensive, it is reasonable to use helium as a tracer gas in the long run due to its high efficiency and reliability. Moreover, helium can also be recovered and recycled in the vacuum helium leak detection system.

In summary, helium is the ideal tracer gas for helium mass spectrometer leak detector!

3.Detailed explanation of the working principle of helium mass spectrometer leak detector

Gas sampling

The helium mass spectrometer leak detector will first sample the gas around the object or system being tested. Through a special sampling pipeline and pump system, the gas that may contain helium leaks is sucked into the instrument. This is like sending out tiny "gas scouts" to explore potential signs of leaks.

Ionization process

The gas entering the instrument is ionized in the ion source. Usually, electron bombardment ion source is used. High-speed electrons collide with gas molecules, causing gas molecules to lose electrons and become positively charged ions. At this time, helium molecules are also ionized into helium ions, ready to enter the next "screening" stage.

Mass spectrometry analysis

The ionized ion beam enters the mass spectrometer, which is the core component of the helium mass spectrometer leak detector. The mass spectrometer uses the combined effect of electric and magnetic fields to separate ions of different masses according to their mass-to-charge ratio. Since helium ions have a specific mass-to-charge ratio, they will separate from other ions and move along a specific trajectory when passing through a carefully designed electric and magnetic field path.

Detection and signal processing

At the end of the mass spectrometer, there is an ion detector. When helium ions reach the detector, a weak current signal is generated. After amplification and processing, this signal can be converted into data information related to the amount of helium leakage. By reading this data, the operator can accurately determine whether there is a leak in the object or system being tested and the extent of the leak.

Helium mass spectrometer leak detectors are widely used in many fields due to their high precision and high sensitivity. In the aerospace field, the sealing detection of key components such as rocket engines and satellite sealed cabins cannot be separated from it. Any small leak may lead to serious flight accidents. In the electronic semiconductor industry, vacuum equipment and packaging processes in the chip manufacturing process also require helium mass spectrometer leak detectors to ensure no leaks to ensure the performance and reliability of the chip. In automobile manufacturing, the sealing detection of automobile parts such as air conditioning systems and brake systems also uses it to ensure the quality and safety of automobiles. In addition, in the fields of electricity, nuclear energy, chemical industry, and medical treatment, helium mass spectrometer leak detectors also play an indispensable role.
