[Question from NMRWiki Q&A forum] What is the optimal sample length with Shigemi tubes?
What is the optimal sample length with Shigemi tubes?
Our coil area length is 16 mm. Should we be making samples exactly 16 mm long in the Shigemi tubes for the best sensitivity (assuming that we are limited on amount of material)?
For example, we use D2O matched shigemi tubes for samples in 90/10 H2O/D2O. Is susceptibility matching affected by switch from D2O to H2O?
Thanks!

[Question from NMRWiki Q&A forum] How much benefit to expect from best NMR tubes?
How much benefit to expect from best NMR tubes?
Hello, how much benefit in resolution and signal-to-noise will we get when using 800 MHz rated tubes (on the 800 MHz instrument) vs 500+ MHz rated tubes?
Is it worth spending the extra money on ultra-high quality tubes for routine work at 800 MHz?
Thanks.
