Analytical Tomography Holder for Ultra-X

Optimizes the acquisition of elemental composition and structural information in three dimensions; allows extremely high tilt angles with large fields of view in restricted pole-piece gaps. Minimal holder volume and materials selection for enhanced X-ray performance. Designed for use with the Ultra-X detector.

Analytical Tomography Holder for Ultra-X

The Analytical Tomography Holder for Ultra-X is optimized for energy dispersive X-ray spectroscopy (EDS). The holder tip and clamps are manufactured from beryllium, which has a low atomic number and thereby reduces X-ray production by the holder. While the holder is optimized for EDS, it is also ideal for any application that requires high specimen tilt angles.

The holder design yields minimal holder volume and is designed specifically for use with Ultra-X detectors. Combined with the beryllium tip and clamp, the holder provides enhanced X-ray performance.

The clamping mechanism accepts specimen grids, standard 3 mm diameter TEM specimens, or focused ion beam lamella. Items included are a specimen holder stand, a specimen loading stand, a Model 9010 Vacuum Storage Container, a clamp tightening tool, and a spare parts kit.

The holder:

  • Has a streamlined specimen clamping mechanism eliminates the shadowing associated with most holders at high-tilt angles
  • Has a retractable clamp that evenly distributes force on opposing edges of the specimen and makes it easy to pre-align or rotate the specimen manually for a dual-axis tilt series
  • Accommodates specimen thicknesses up to 250 μm
  • Has a tapered, self-centering specimen receptacle guides the specimen into position
  • Is compatible with the TEM’s touch alarm, which stops goniometer movement in the event that a pole touch occurs

Available for Thermo Fisher Scientific microscopes.
