NMR Sample Tube選用對照表

經濟型NMR Sample Tube與其他廠牌的型號對照表
Wilmad has been the world’s largest manufacturer of magnetic resonance consumables for the past 6 decades. The MHz frequency rating for our products is based on the various tolerances on Camber and Concentricity and was set to guarantee the shimming quality and signal lock level for certain NMR Standards at different magnetic fields. We have been using this rating standard, deemed the highest in the industry, since the first day of production.
Recently some of our competitors altered this standard, especially for High-Throughput Economy Tubes (N51A Glass or equivalent) by advertising inferior tubes for higher frequency experiments. To avoid lowering SNR for your experiment we offer a complete NMR Economy Tube Cross Reference Guide based on actual Camber and Concentricity specifications. The products listed on the same row will have the same performance at the same magnetic field if the specifications of our competitors’ product are guaranteed as advertised. From this head-to-head comparison Wilmad proves its 60 year philosophy again – we are committed to providing customers with cost-effective NMR consumables of the highest quality.

Note: The MHz rating, camber and concentricity shown are for Wilmad tubes only.

經濟型與精密型NMR Sample Tube的比較表

Note 1: Impact on shimming quality varies upon magnetic field strength. Economy tube recommended for 1D low field experiments.
Note 2: Sample volume reproducibility refers to the maximum volume fluctuation when filling different NMR tubes to the same height. This number correlates to the reproducibility of time domain signal amplitude between different runs.
