Energy Dispersive X-ray Spectrometry
Energy Dispersive X-ray Spectrosmetry (EDS) is opening new dimensions for biological electron microscopy, adding compositional information (colour EM) to greyscale ultrastructural images in SEM and TEM. The additional elemental information can be used for a variety of applications including, but not restricted to, measuring the quantity and localising endogenous biological elements, imaging ultrastructure without any stain in resin-embedded and cryo-specimens, investigating the location and distribution of nanoparticles in cells and tissues, determining ion gradients across specified areas, investigating the composition of pollutants or contamination of biological material and the identification of a diverse range of stains and immunolabels.

Our EDS systems provide the flexibility and accuracy required for biological analysis, including:
- Low kV analysis for high resolution data (<2kV)
- Detection of light elements in biological samples (incl. nitrogen) using windowless detectors
- Sensitivity for low dose conditions and cryo-EM
- Fast and accurate compositional analysis with large area detectors
- Easy to interpret analytical data with automatic identification of elements
