Easy Tuning

Protasis probes employ a small solenoidal microcoil for radiofrequency detection.  This coil is designed and manufactured to remain in intimate contact with the outer surface of the NMR flowcell.  Contrary to tube-based probes where sufficient tolerance must be maintained to facilitate tube removal and insertion, the only material changing from sample-to-sample in Protasis probes is the sample itself.  RF tuning is easily performed using standard “tune” and “match” wands, and due to the minimal perturbation experienced by the microcoil from sample-to-sample, does not typically require readjustment except when a new solvent is introduced.  This means less worry for you, less time required for probe adjustment, and more time to focus on what is important – your sample and your data.
