WETSEMTM Technology

  • High resolution imaging of fully hydrated samples
  • Greatly reduces prep time as well as artifacts
  • Capsule and base fits standard SEMs
  • Safe and simple to use
  • Achieve reliable, reproducible, quantifiable results

Electron microscopy (EM) is today's primary tool for high-resolution imaging – the cornerstone for research into living organisms and our material environment.

But because EM requires that samples be placed in a vacuum, it has not been suitable for examining wet samples. This single drawback has been a major impediment to the use of EM for biomedical research, as well as for many other clinical and industrial applications. Until now, the only means of imaging a wet sample with EM was to freeze or dry it, effectively changing it's nature in the process. Such sample preparation is also time-consuming, costly, and often introduces artifacts.

El-Mul (QuantomiX) WETSEM® – developed with the cooperation of some of the world's leading life sciences and materials science researchers and labs – dramatically reduces the preparation needs for high-resolution imaging of wet samples, making imaging easier and faster. It also eliminates many of the artifacts that result when preparing wet samples for EM, opening up opportunities for new research methods as well as new processing methodologies in a variety of fields.

WETSEM® also uniquely enables imaging of samples that contain oily and volatile materials.

Also for the first time, WETSEM® enables microanalysis using energy dispersive spectrometry (EDS) of wet samples in their native state, a long-awaited capability for many industrial and research labs.
