An Advice about Shimming in High-Resolution Nuclear Magnetic Resonance

TL;DR

This paper reviews three active shimming methods in high-resolution NMR, comparing their advantages and shortcomings, and provides practical advice on their application to improve spectral quality.

Contribution

It offers a comparative analysis of manual shimming, lock optimization, and gradient shimming, along with practical guidance for their effective use in high-resolution NMR.

Findings

Gradient shimming provides the highest spectral resolution.

Manual shimming is time-consuming but flexible.

Lock optimization offers a good balance between ease of use and performance.

Abstract

Three methods of active shimming in high-resolution NMR in existence (manual shimming, lock optimization and gradient shimming) are briefly discussed and their advantages and shortcomings are compared and also an advice on their use is given.
