The MCF staff can assist users in preparing samples for the following techniques: 

  • carbon evaporation (Cressington 108A carbon coater, Quorum Q-150 T ES)
  • gold / palladium sputter coating (60:40 Au/Pd alloy; Hummer V sputter coater system)
  • UV / ozone cleaning (SEM: Hitachi ZoneSEM)
  • UV/ ozone cleaning (TEM:  Hitachi ZoneTEM)
  • vacuum oven (drying / driving off solvent)
  • IR heat lamp (sample outgassing / adhesive curing) 

The MCF provides some types of SEM sample stubs and adhesive materials (e.g. carbon dots, carbon tape, copper tape, colloidal graphite / carbon paint, silver paint, high-temperature nickel paste, etc).  

The following tools modify bulk samples to have the optimum size, shape, and surface finish for imaging and analysis 

  • Gatan:
