A high-resolution 10mm probe achieves high sensitivity from a large  volume of samples as well as high resolution due to advanced probe  technology enhancing homogeneity of the magnetic field for that  volume.
A ¹³C spectrum observed using a 10mm probe (Fig. 1) exhibits resolution as high as that obtained using a 5mm probe (Fig. 2), with  much higher sensitivity. Owing to sufficient resolution and sensitivity, it is possible to quantify atactic parts of polypropylene contained  by about 0.1%.
Thus, a high-resolution 10mm probe is useful in the research of  polymers.
