DynoMag
Imego has developed a portable AC Susceptometer for dynamic magnetic analyses. It has unrivaled performance with the largest frequency range available 1Hz - 500 kHz. This instrument can analyze magnetic samples in the form of liquids (for example, ferrofluids), powders, and solids. It creates a "magnetic fingerprint" of the material making it useful for a wide variety of applications ranging from measurements on magnetic particle systems to geological soil analyses and medical diagnostics. The DynoMag system is available as product and for dynamic magnetic characterization of samples sent to Imego.
DynoMag HF
For hypothermia applications, in order to reach the Néel relaxation frequencies for small particles (below about 12 nm for magnetite nanoparticles at room temperature), we have recently developed a high frequency version of the DynoMag system – DynoMag HF. With this new AC susceptometer Imego can today measure dynamic magnetic properties from 25 kHz to 10 MHz combined with a high magnetic sensitivity. Thus, together with the medium frequency range DynoMag system we can measure AC susceptibility in the frequency range from 1 Hz up to 10 MHz with a very high sensitivity. The system is available for dynamic magnetic characterization of samples sent to Imego
Measurement on a Micromod 130-nm particle system. Susceptometry data were fitted to a single core Debye model, and the results were consistent with VSM analysis.
