Kea2 DC to 400 MHz NMR Spectrometer


The Magritek’s Kea2 is a lightweight, compact and portable, yet powerful, nuclear magnetic resonance (NMR) spectrometer with the following features:

  • Models from DC to 400 MHz
  • Optional second transmit channel
  • Optional high stability oven controlled oscillator
  • Optional four channel imaging module
  • External input trigger
  • Can operate off a 24 V battery


The extended operating range and features of the Kea2 series makes it useful for a wide range of applications:

  • Spectroscopy, time domain relaxation and imaging
  • Mobile permanent magnets
  • High frequency superconducting magnets
  • Ultra-low frequency systems (e.g. Earth’s Field)
  • Single-sided NMR

Direct Digital Transmit and Detect

The Kea2 uses no intermediate mixing frequencies — meaning no quadrature issues. Kea2’s 1 GHz digital transmit circuit performs direct waveform synthesis at up to 400 MHz. The receive module directly digitises the NMR signal at 100 MHz for a high quality, low noise NMR signal. This is the same technology used in most modern high field NMR spectrometers but is available with Kea for a fraction of the price.

It is a lightweight, low-footprint Kea2 spectrometer which is convenient to use in almost any environment. Powered by two standard 12 V car batteries, the Kea2 can be operated far afield in any remote location.
