Standard Practice for Measuring and Reporting Performance of Fourier-Transform Nuclear Magnetic Resonance (FT-NMR) Spectrometers for Liquid Samples
 N E2977

Annotation

This practice covers procedures for measuring and reporting the performance of Fourier-transform nuclear magnetic resonance spectrometers (FT-NMRs) using liquid samples.

This practice is not directly applicable to FT-NMR spectrometers outfitted to measure gaseous, anisotropically structured liquid, semi-solid, or solid samples; those set up to work with flowing sample streams; or those used to make hyperpolarization measurements.

This practice was expressly developed for FT-NMR spectrometers operating with proton resonance frequencies between 200 and 1200 MHz.

This practice is not directly applicable to continuous wave (scanning) NMR spectrometers.

This practice is not directly applicable to instruments using single-sideband detection.

Units—The values stated in SI units are to be regarded as the standard. No other units of measurement are included in this standard.

This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
