From: Broadband stripline Lenz lens achieves 11 × NMR signal enhancement
Comparative spectra for different nuclei using a dummy chip, and the broadband S3L add-on. (a) Proton \({}^1\)H spectra at 500 MHz. The insert shows more detail for the region between 3.4 ppm to 4.2 ppm. (b) Lithium \({}^7\)Li spectra at 194 MHz. (c) Sodium \({}^{23}\)Na spectra at 132 MHz. (d) Phosphorous \({}^{31}\)P spectra at 202 MHz. (e) A proton \({}^1\)H nutation spectrum obtained using the S3L, corresponding to the orange curve in (a). (f) MRI of DI water at the center of the stripline with an S3L chip (left) and MRI of DI water with a dummy chip (right). A profile of signal intensity along the red dotted line is addressed.
