Traditional challenges are, however, that 13C-detected NMR is insensitive despite its high resolution, and that MS-based techniques cannot easily differentiate positional isotopomers. In addition, current 13C NMR or LC/GC–MS has limitations in ...

    Some of the most commonly employed carbon blacks (Carbograph 1,2,4,5 from Lara and Carbopack X form Supelco), were evaluated by the BET surface characterization method for pore size distribution, porosity and specific surface. This information is often incomplete as furnished by manufacturers and is needed for a deeper understanding of carbon adsorption properties in chromatography.

    2014-5-26 · The black dashed lines in the centre indicate flashing (F) and decarbonation during vacuum sampling from the carbon flooded reservoir. Depending on the amount of dissolved carbonates/silicates, flashing takes place at varying SI-pH coordinates within the grey lines, resulting in different end points (squares) where no more CO 2 can degas.
