Samples may become contaminated by titanium if they have line-of-sight to the pump. Also, titanium is a very hard material, so titanium film which builds up on the inside of the chamber may form flakes which fall into mechanical components (typically turbomolecular pumps and valves) and damage them. Many chambers containing TSPs also have an ...
Ion pumps; Titanium sublimation pumps; Non-evaporable getter (NEG) pumps; Cryopumps; Diffusion pumps, especially when used with a cryogenic trap designed to minimize backstreaming of pump oil into the systems. Turbo pumps and diffusion pumps rely on supersonic attack upon system molecules by the blades and high speed vapor stream, respectively.
Titanium is a chemical element; it has symbol Ti and atomic number 22. ... titanium that is evaporated from filaments is the basis for titanium sublimation pumps, ...
Close-space sublimation, the material, and substrate are placed close to one another and radiatively heated. Pulsed laser deposition: a high-power laser ablates material from the target into a vapor. Thermal laser epitaxy: a continuous-wave laser evaporates individual, free-standing elemental sources which then condense upon a substrate.
The Wasserstrom Company is a restaurant supplier based in Columbus, Ohio with distribution centers located across North America. [2] The Wasserstrom Company is a family-owned and operated business that was founded in 1902 by Nathan Wasserstrom. [3]
Family patriarch Simon Lazarus (1808–1877) opened a one-room men's clothing store in downtown Columbus in 1851. By 1870, with improvements to the industry in the mass manufacture of men's uniforms for the Civil War, the family business expanded to include ready-made men's civilian clothing, and eventually, a complete line of merchandise.

Dye-sublimation printing (or dye-sub printing) is a term that covers several distinct digital computer printing techniques that involve using heat to transfer dye onto a substrate. The sublimation name was first applied because the dye was thought to make the transition between the solid and gas states without going through a liquid stage.
