WebNov 12, 2024 · Outgassing Elements in Electron Microscopes. When electron microscopes function in high vacuum levels, all wet samples loaded into the imaging chamber will instantly begin to outgas. Particular samples contain microstructures that will combat the phase change, offering positive results with no key concerns. A common … • Austenitic stainless steels are the most common choice for high vacuum and ultra-high vacuum systems. Not all alloys are suitable; e.g. the free-machining 303 steel contains sulfur, which tends to outgas. Alloys with good weldability under argon arc welding are usually chosen. • Mild steel can be used for moderate vacuums above 1×10 torrs (1.3×10 kPa). Outgassing can be lowered with suit… WebGraphite and C-C materials for UHV applications 25 June 2003 1.0E-13 1.0E-12 1.0E-11 10 100 Time (hours) Outgassing (mbar.l/s.cm2) Heat treated Graphite Heat treated Graphite with outgassing holes Heat treated C-C Residual outgassing of the set-up Static Outgassing after bakeout - after a heat treatment at 1000°C during 2 hours - 24 hours at ... simvastatin and erectile dysfunction
