HYDROGEN CONTENT OF AVIATION TURBINE FUELS BY NUCLEAR MAGNETIC RESONANCE (NMR): ASTM D3701
EXPLANATION
This test method provides a quick, simple, and precise alternative method to that using empirical correlationships.
TEST SUMMARY
A sample of the fuel is compared in a continuous wave, low-resolution, nuclear magnetic resonance spectrometer with a reference standard sample of pure hydrocarbon. The method is specifically based on Newport analyzers.
TEST PRECISION
This test method has a repeatability of 0.09 mass % and a reproducibility of 0.11 mass %. It has been reported that the hydrogen content determined by this test method is biased high with respect to the expected value for pure known materials.
