Characterisation and evaluation of reference materials for black carbon analysis using elemental composition, colour, BET surface area and C-13 NMR spectroscopy (2008)

Hammes, Karen, Smernik, Ronald Josef, Skjemstad, Jan Otto, Schmidt, Michael W. I.

A recent comparative exercise found that different black carbon (BC) quantification methods produced widely varying results for a set of BC reference materials that included three laboratory-produced...
