The GC/MS software includes a library of over 250,000 compounds. When the library is searched for the unknown compound, it can frequently give a tentative identification to the unknown; hence the name Tentatively Identified Compound – TIC.I walked between Joan and Van, having survived the ordeal you have been through, nitric acid.
