This section provides you with some extra information about electrospray deposition and our systems. Although all you need to do is find a suitable solution for the molecule that can also give a stable electrospray jet, some specific examples can be found in the literature, some of which can be found on our research page.

Pumping requirements

Our UHV4 systems are tested with the following pumping arrangement. Equivalent pumps from any manufacturer of your choice should give the same performance (examples given are for Varian pumps):

Stage 1: Scroll or rotary vane with displacement >100 l/min (e.g. SH110 scroll) - typical pressure 10^-1 mbar

Stage 2: Scroll or rotary vane with displacement >100 l/min (e.g. SH110 scroll) - typical pressure 10^-2 mbar

Stage 3: Turbomolecular pump with displacement > 70 l/s (e.g. V80 Macro-torr turbo backed by SH110 scroll) - typical pressure 10^-5 to 10^-6 mbar.
Stage 4: System prep-chamber (variety of pumping arrangements typical of systems with a base pressure in the 10^-10 mbar range or lower) - typical pressure during deposition <10^-8 mbar
