    • Gas chromatography/mass spectrometry (GC/MS-SIM) is an excellent technique for performing both qualitative and quantitative analysis of DNA base damage products that are formed by exposure to ionizing radiation or by the interaction of intracellular DNA with activated oxygen species. This technique commonly uses a hot formic acid hydrolysis step to degrade the DNA to individual free bases. However, due to the harsh nature of this degradation procedure, the quantitation of DNA base damage products may be adversely affected...

    • Gas chromatography-mass spectrometry (GCMS) is the preferred method for the analysis of drugs/metabolites in biological specimens with use of isotopically labeled analogs of the analytes as internal standards (ISs). An important aspect of the chemical derivatization (CD) for GC-MS analysis is that the CD products derived from the analyte and the selected IS must generate ions suitable for designating the analyte and the IS. These ions should not have significant cross contribution (CC), i.e., IS contribution to the intensities of the ions designated for the analyte, and vice versa...
