  • It is important that you contact your instrument scientist as soon as you receive your experiment start date.
  • Discuss any shipment of equipment and samples with the instrument scientist and User Office prior to shipment and notify both once you receive delivery notice.
  • If you need a special sample holder or ancillary equipment, please make arrangements with your instrument scientist before your experiment start date.
  • Complete your online training as directed by the User Office.
