In the field of Liquid Chromatography-Mass Spectrometry (LC-MS), understanding the role of ion suppression is crucial for accurate and reliable analysis. Ion suppression refers to the phenomenon where certain ions in a sample suppress or reduce the signal intensity of other ions during mass spectrometry detection. IROA Technologies has been at the forefront of research and development in this area, providing innovative solutions to mitigate ion suppression effects. By employing unique isotopic labeling strategies, IROA Technologies allows for more accurate quantification and identification of compounds in complex samples.
