    Abstract: A gas chromatographic method for detecting a first marker and a second marker in a fuel in two channels: (i) a first capillary column coated with polysiloxane and a second capillary column coated with polyethylene glycol; and (ii) a third capillary column coated with polymethylphenylsiloxane and a fourth deactivated capillary column. The steps are: (a) introducing a first sample into the first column to produce a first effluent; (b) introducing only a portion of the first effluent into the second column to produce a second effluent; (c) allowing the second effluent to pass through a mass spectrometer; (d) introducing a second sample into the third column to produce a third effluent; (e) introducing only a portion of the third effluent into the fourth column to produce a fourth effluent; (f) allowing the fourth effluent to pass through a mass spectrometer.

    Abstract: A method for marking a petroleum hydrocarbon or a liquid biologically derived fuel by adding to the petroleum hydrocarbon or liquid biologically derived fuel a compound having formula C{Ph(R1)i(OR2)j}2{Ph(R3)m}{OR4)n}{Ph(R5)o(OR6)p}, wherein Ph represents a benzene ring, R1, R3 and R5 independently are C1-C18 alkyl or C4-C18 heteroalkyl; R2, R4 and R6 independently are C1-C18 alkyl or C4-C18 heteroalkyl, i, j, m, n, o and p independently are zero, one or two. Each compound having formula C{Ph(R1)i(OR2)j}2{Ph(R3)m(OR4)n}{Ph(R5)o(0R6)p} is present at a level from 0.01 ppm to 20 ppm.
