Abstract
A method for detecting the presence of or quantification of carbon black and/or black carbon in a sample or carrier medium. The method includes providing the sample or carrier medium without labelling or pre-treatment of the carbon black and/or black carbon particles; illuminating the sample or carrier medium at a temperature below 90° C. by a pulsed light with a pulse duration below 500 femtoseconds, a repetition rate above 1 MHz with an average power below 20 mW, and a wavelength of a femtosecond laser pulse ranging from 700 to 1200 nm, to generate non-incandescence related light emission from the carbon black and/or black carbon particles; and analysis of the light emission.
