Mass spectrometer - helium method | helium-leak.eu

The principle of leak detector is based on a sector field mass spectrometer. Analyzed entry gasses (in this case Helium) are ionized in vacuum. Ions of helium are accelerated using added voltage and further separated in the magnetic field. The ion current is, using a special detector, turned into an electric current.

An Introduction to Vacuum Pumps

An Introduction to Vacuum Pumps

Jan 13, 2016 · The vacuum pump functions by removing the molecules of air and other gases from the vacuum chamber (or from the outlet side of a higher vacuum pump if connected in series). While the pressure in the chamber is reduced, removing additional molecules becomes exponentially harder to remove. As a result, an industrial vacuum system (Fig. 1) must be .

Mass Spectrometer Working Principle - Instrumentation Tools

Mass Spectrometer Working Principle - Instrumentation Tools

A mass spectrometer is a gas analyzer in which sample molecules are pulled into a vacuum system then ionized (using an electrical charge), which are then separated by mass-to-charge ratio by the quadrupole and the detector measures the equivalent ion current (quantitative) which is the analyzer output reading. Parts of Mass Spectrometer:

Hybrid vacuum pumps that combine attributes of rotary vane and diaphragm pumps are available. These pumps are especially well suited for applications that need the "fine vacuum" (10 –3 Torr) range of a rotary vane pump, but which have high vapor loads that would create a need for very frequent oil changes. Freeze dryers are a typical application.
