Sample Preparation

Successful TEM depends on many parameters, one being the preparation of high quality specimens. With the tremendous advances in spatial and spectral resolution of state of the art microscopes, the quality of the samples examined has become a major limiting factor for quantitative analysis at the nanometer scale.

StEM has advanced specimen preparation facilities and the know-how to meet today’s requirements for a broad range of material systems. The methods employed include plan-view / cross-section preparation of hard materials using automated tripod polishing and low-energy / low temperature ion beam milling, ultramicrotomy for both organic and inorganic materials, as well as electrolytic polishing of metals and semiconductors. In 2015 we added a FIB instrument for precision sample machining.

The sample preparation facility houses dedicated equipment including:

  • Gatan Precision Ion Polishing System (PIPS) Model 691 with cooling and low energy
  • Gatan Precision Ion Polishing System II (PIPS2) Model 695 with cooling and low energy

  • MED 010 Balzers Union Carbon Coater
  • Leica EM ACE600 High Vacuum Sputter Coater

  • Buehler Isomet low speed saw
  • K.D. Unipress (I-B-S) Wire saw type WS-22
  • Well wire saw Model 3242

  • Gatan Ultrasonic Disc Cutter Model 601
  • South Bay Technology Abrasive Slurry Disc Cutter Model 360

  • Optical Microscopes

  • Buehler Minimet 1000 Grinder/Polisher
  • Gatan Disc Grinder 623
  • Gatan Dimple Grinder 656

  • Allied MultiPrep System TEM wedge polisher (tripod polisher automated)
  • South Bay Technology Tripod Polisher 590 TEM wedge polishing kit (manual)
  • South Bay Technology Small Angle Cleavage Technique Kit (SACT)

  • Leica EM UC6/FC6 Ultramicrotome
  • Leica EM Trim 2
  • Leica Ultracut UCT

  • Struers Tenupol 5 electrolytic polisher
  • Struers Tenupol 3 electrolytic polisher

  • Jurca Coaxial optical distance measurer
