micrOTOF II
The micrOTOF II was installed during our major upgrade of
facilities in 2013. This is used exclusively by the MS service to
run the small molecule ESI accurate-mass samples. It can
be run in both automated and manual modes. In automated mode the
solvent system is MeOH/Water (50%), in manual mode a wide range of
solvents can be used.
