Helium detection instrumet

A mass spectrometer that uses helium as a leaky gas and uses a gas analyzer to detect helium gas.The background noise of helium gas is low, the molecular weight and the viscosity coefficient are small, so it is easy to pass through the hole and easy to spread.In addition, helium is an inert gas, which does not corrodes the equipment, so helium is often used as a leaking gas.The gas is sprayed onto a container that is connected to a gas analyzer (adjusted to work only in response to helium).
