Catalytic Hydrogenation of Solvent-Refined Lignite to Liquid Fuels

Sampling system for mass spectrometry of high boiling mixtures using gas chromatography-mass spectrometry

“…For this sample, the FID response reached a maximum after about 10 min, and the sample bled into the MS for at least 1 hr. It appears that the least volatile component of a mixture must have a vapor pressure of [5][6][7][8][9][10] Torr for successful analysis using the system described. No decomposition of these samples was noted, but a metal inlet system may cause difficulty with heteroatom compounds.…”
