Active Spectrum was spun out of a project funded in 2002 by the MIT Deshpande Technology Innovation Center. That project was called The Nanogate: A Tunable MEMS LC Filter. Active Spectrum now produces the world's smallest electron spin resonance (ESR/EPR) spectrometer, called Micro-ESR. Applications of Micro-ESR include analysis of antioxidants, lubricants, crude oil, catalysts, biodiesel stability, shelf life of vegetable oil, beer and wine, spin trapping and countless other uses. Active Spectrum also develops custom sensors for the chemical, petroleum, and defense industries.
