The world's only solution to quickly increase the sensitivity of your X-Band Spectrometer

With eSPECT+ Expansion module the new era of EPR Spectroscopy is within your reach


Ultra High sensitivity for aqueous and lossy samples

We present the world’s first expansion module dedicated to commercially available X-band Spectrometers. The multiharmonic analyser increases the sensitivity of the spectrometer’s detection even system even up to 10 times!

Therefore it is possible to measure any solid sample with significantly better sensitivity or to reduce the power level and measure samples containing high concentrations of water.


improved S/N ratio

perfect solution for detecting weak signals

increased sensitivity

Compatible with comercially available spectrometers!

Our multiharmonic analyser gives you a great opportunity to upgrade your current X-Band Spectrometer in an easy and quick way. eSPECT + is compatible with:

  • Bruker Elexys
  • Adani SpinScan

If you have any other spectrometer, or maybe your own design, and still would like to use our multiharmonic analyser, don’t hesitate to contact us! We are always open to all discussions and we will do our best to find the best solution to meet your needs.

Take a look and discover the full potential of eSPECT+

Press the button and see how you can improve your S/N ratio !

You can compare the primary signal from the spectrometer to the signal acquired through multiharmonic expansion module.

The parameters of the experiment:

  • the nitroxide solution 3CP,
  • sweep 70 G,
  • modulation amplitude 20 G.

Low S/N Ratio

More reserach posibilities and new applications

Our eSPECT+ device allows you to lower the frequencies and at the same time collect high-quality signals with a great signal-to-noise ratio. Owing to that additional feature you will have a chance to examine creams, liquids, drugs and biological samples like zebrafish embryos.
