Surface Modification/Analysis

The SimulTek Inert Gases Extracting Device (IGED-2018) is a scientific experimental device applies to extracting inert gases from various types of water samples (a sample of groundwater, etc.). The device is capable of extracting, purifying and concentrating the inert gases, including He, Ne, Ar, Kr, Xe etc. from the sample of water by serial methods of evaporating, concentrating, and sublimating under a high vacuum condition, for scientific experiment and analytical measurement purpose. SimulTek has also developed physical principles, experimental technique and methodology (Argon filter for IGED-2018) for purification from Ar of a mixture of inert gases.

This facility has been built at SimulTek with emphasis on development of an ion-beam surface treatment to achieve specific charge dissipative properties for outside surfaces of thin space polymer films. Ion-beam surface treatment of selected hydrocarbon and partially fluorinated polyimide films allows achieving controlled surface modification and a long multi-year shelf life for the treated materials. The roll-to-roll driving mechanism has been designed to provide for convenient computer-controlled tape feed through the ion beam treatment facility. A custom-made ion beam source (ion beam gun) is used for continuous ion beam treatment of a thin polymer tape.

The gas probe mass spectrometer system was designed to drastically improve the efficiency of the mass-spectroscopic analysis. This was achieved by designing and adding a three-stage differential pumping system to the mass-spectrometer. Features: The designed and created gas probe mass spectrometer system includes a 3-stage differential pumping system (two turbopumps TwisTorr84 FS and two scroll pumps SH-110), a mass spectrometer RGA100 SRS, a support frame and electrical and electronic systems.
