    heavy oil - Extended Range ESR

Contact Us
The extended range benchtop ESR has an electromagnet that can sweep up to 7000 Gauss. Excellent sensitivity including aqueous samples. Not only an excellent spectrometer for spin trapping and spin labeling experiments, the increased range allows for the observation of complete transition metal spectra as well. Variable temperature options are available, including use at 77 K.

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.
