Silicon Oxide Membranes for TEM and X-Ray Microscopy

Norcada SiO2 membranes feature thin, amorphous SiO2 membranes held at the centre of a support mesh. The SiO2 membranes are ideal for applications which require Nitrogen and Carbon free membranes . 

SiO2 membranes are constructed with pure SiO2 regions nested within a support membrane. This structure allows for up to 24 unique sample regions within the central area of the device, ideal for characterization of multiple samples on a single device.

SiO2 membranes are available with a variety of features in standard configuration:

  • Carbon and Nitrogen free viewing areas for EDX elemental analysis and X-ray spectroscopy of nanomaterials and biological material
  • Amorphous films, compatible with Selected Area Electron Diffraction (SAED) and X-ray Diffraction Spectroscopy (XRD) analysis
  • Low resistivity Silicon Frames for charge and heat dissipation
  • Single membranes, or membrane arrays with up to 24 per device
  • Membranes from 5μm to 50μm diameter
  • Square 5mmx5mm frames for X-ray microscopy
  • Circular 3mm dia. frames for standard TEM sample holders
