What is a Helium Mass Spectrometer Leak Detector? This “sniffed” gas is passed to a Helium sensor or mass spectrometer to record any elevated concentrations. In this case, the chamber of concern filled with helium and a helium gas leak detector is passed around the chamber, weld areas, connectors, seals, flanges and ducts for inspection and to see if any He is leaking. Once method is called the “local-sniffer (sample under pressure)” method. There are several ways of undertaking a Helium Leak test using a Helium Gas Sniffer. Helium is non-toxic, non-flammable, non-explosive, and relatively safe for humans unless it is inhaled in a large quantity.Helium constitutes a relatively low concentration of gaseous compounds found in the air, meaning that there is not a high degree of background gas that can affect the reading.Using helium for trace gas leak detection has many advantages. Why is Helium Used in Trace Gas Leak Detection? With that said, excessive inhalation of the gas can have asphyxiation effects due to the lack of oxygen. In general, helium gas is non-toxic and inert, decreasing its risk to humans. It finds uses in welding for other metals, in rocket propulsion, in meteorology, in cryogenics, and in high-pressure breathing operations. It can be isolated from natural gas when the other compounds are liquefied at a low temperature and high pressure- the helium remains as a gas. Helium is a gaseous compound that is colorless, odorless, and tasteless. If the sample gas has an amount of 'helium' the change in conductivity as a result of the physical thermal change will be detected and translated into a useful calibrated He concentration. These sensors are called thermal conductivity detector (TCD), referred to sometimes as a katharometer. Two thermal element compared normal air with the gas sample. Therefore, the change in thermal conductivity (since it is lower in molecular weight) compared to air, is an excellent physical method used to make a helium sensor. Since helium is an inert gas, chemical methods to detect He gas, such as redox reaction that are used in electrochemical and semiconducting metal oxide gas sensors do not work.

A helium leak detector is imperative to be used in high magnetic fields such as those found around the outside of Magnetic Resonance Imaging (MRI) scanners. Helium is used to cool the superconducting magnets in a MRI scanner to a temperature below 4,15 Kelvin (-269☌). Since helium is a very small molecule, it can leak and hence, all seals and welds must be perfect in an MRI. Since helium is light, it is a excellent tracer gas and can penetrate leaks or compromised seals to then be detected and ultimately find a leak. Some reputable options include: These analyzers are used with a probe to detect helium leaks in various equipment, vacuum equipment, spectrometers and cryogenics.
