Active Spectrum Products - Innovation in Magnetic Resonance +1 650 212 2625

Active Spectrum Inc.'s Online Micro-ESR™ Sensor can be used in a wide variety of process applications where continuous, real-time measurement of free radicals (e.g. soot, asphaltene, vanadium) is required.

	The Benchtop Micro-ESR™ includes our patented miniature electron spin resonance spectrometer, operating at either 3.4 GHz or 9.6 GHz, with a sweep range of up to 400 Gauss and sub-micromolar sensitivity in aqueous solution. Also included are a full Windows XP computer system, integrated touchscreen, Ethernet and multiple USB ports. See data sheet	The Micro-ESR™ sensor can be installed in a flow-thru configuration for automated fluid monitoring and process applications. Micro-ESR™ provides direct, highly specific chemical information on fluid composition in real-time. Examples of applications include monitoring metals concentration in fluids, monitoring asphaltene content in crude oil, and measuring lubricant oxidation. See article
