In LCMS TIC I am getting main peak as a negative peak

The total ion current (TIC) chromatogram represents the summed intensity across the entire range of masses being detected at every point in the analysis. The range is typically several hundred mass-to-charge units or more. In complex samples, the TIC chromatogram often provides limited information as multiple analytes elute simultaneously, obscuring individual species. Webb20 maj 2024 · In forensic toxicology, high-performance liquid chromatography tandem mass spectrometry (LC-MS-MS) is increasingly used for the fast and sensitive measurement of a wide range of drugs.
