Instrument status: Some Issues Some Issues, 14.4.2025 11:10, RBSE detector movement issue - sometimes gets stuck when retracting to parking position. Pull out the detector manually by turning the turnwheel on the backside of the detector, if necessary. Service request sent to Tescan, repair date unknown.

Description:

Scanning electron microscope (SEM) MIRA3 XMU

Description

• Scanning electron microscope (SEM) is used to study the morphology and topography of conductive and non-conductive materials in high resolution (micro to nano-scale).
• Observation of surface samples with high depth of focus using multiple detection system (SE, BSE, STEM) including elemental analysis using energy dispersive spectrometer (EDS).

Applications

• Observation of both the surface and internal structure of micro and nano-objects (phase interface such as matrix-filler/reinforcement, particle distribution, aggregates and defects, fracture surfaces, porous 3D materials, units of supramolecular structure, etc.)
• evaluation of the shape and dimensions (length, diameter, volume, roughness) of powders, tubes, short fibers
• fast and highly accurate chemical microanalysis and elemental mapping of a sample surface
• qualitative elemental analysis including determination of the distribution of each element
• quantitative analysis of the individual elements in a sample
• The structural analysis of polymeric materials, biopolymers and composites, biomaterials, ceramics, bones, teeth, substrates for tissue engineering, etc.

Specification

• High Brightness Schottky Emitter
• Detectors:
SE, BSE, In-beam SE, In-Beam BSE
