Sample volume: In comparison to MS, which generally requires only approximately 10 50 μL, H NMR sample requirements are much higher.
In qNMR sensitivities are normally quoted in the micro-to millimolar range and the number of metabolites detected is normally in the low hundreds [30,34]. 5. Sample volume : In comparison to MS, which generally requires only approximately 10 50 μL, H NMR sample requirements are much higher.
"The requirements are much more onerous," said Robert Hoskins, president of the NuRock Companies, a developer in Alpharetta, Ga.
But other requirements are much tougher, like a substantial increase in the amount of money the state must recover from Medicaid fraud prosecutions, a target much higher than the amount any state has recovered to date.

And if they want to lend money their capital adequacy requirements are much less onerous in the first two years of operation, he added.
The fourth and fifth requirements are much more difficult, and I think this is where a lot of companies get tripped up.
Whereas recent nest web studies greatly increased our understanding of nest tree use by woodpeckers, knowledge on woodpeckers foraging requirements is much less developed.
