Tentatively identified compound or “TIC” means a non-targeted compound detected in a sample using a GC/MS analytical method which has been tentatively identified using a mass spectral library search. [Alkane compounds attributed to a petroleum product will be summed and reported as total alkanes. For purposes of TIC identification, the total alkanes are treated as one compound.] An estimated concentration of the TIC is also determined.

More Definitions of Tentatively identified compound

Tentatively identified compound or “TIC” means a chemical compound detected in a sample that is not a target compound, internal standard, system monitoring compound or surrogate.

Tentatively identified compound means a non Target Analyte List organic compound detected from laboratory analysis of a sample using a Gas Chromatograph/Mass Spectrometer (GC/MS) under an approved EPA laboratory method. Tentatively Identified Compounds (TICs) are identified from reconstructed chromatograms. TICs should have a 80% spectral match, however, professional judgment is considered by the Department in the determination and identification of the TIC. A standard must be run to make a positive identification of a TIC. The analytical results are considered estimates of concentration.
