The ROYALPROBE™ combines the best features of an inverse probe for 1H & 19F measurements with a broadband probe for heteronuclear (31P to 15N, 39K, and 109Ag) measurements.
This combination of features removes the need for an extra probe in regular instrument use and lessens the demand for probe changes. The Autotune unit makes full sequential multinuclear measurements possible. The sample is perfectly tuned and matched in the solvent and temperature of the user's choosing.
