Mass Spectrometry and Ultra-High Vacuum

sublimation pumps, ion getter pumps, and cryogenic pumps. Operation of all these pumps requires pre-vacuum below approximately 10-2 mbar. For this purpose a "pre-vacuum pump", "fore pump" or "backing pump" is used, usually a rotary oil pump (often used in synthesis chemistry laboratories). Recently, rotary oil pumps are increasingly replaced by .

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:

Gas Chromatography Mass Spectrometry

A capillary column most often used in the chromatograph because the entire MS process must be carried out at very low pressures (~10-5 torr) and in order to meet this requirement a vacuum is maintained via constant pumping using a vacuum pump. It is difficult for packed GC columns to be interfaced to an MS detector because they have carrier gas .

Turbomolecular pump - Wikipedia

A turbomolecular pump is a type of vacuum pump, superficially similar to a turbopump, used to obtain and maintain high vacuum. These pumps work on the principle that gas molecules can be given momentum in a desired direction by repeated collision with a moving solid surface. In a turbomolecular pump, a rapidly spinning fan rotor 'hits' gas molecules from the inlet of the pump towards the .

Vacuum pump - Wikipedia

History Early pumps. The predecessor to the vacuum pump was the suction pump. Dual-action suction pumps were found in the city of Pompeii. Arabic engineer Al-Jazari later described dual-action suction pumps as part of water-raising machines in the 13th century. He also said that a suction pump was used in siphons to discharge Greek fire. The suction pump later appeared in medieval Europe from .
