Mass-to-charge Ratio

The mass-to-charge ratio (m/z) is a fundamental metric of ion mobility spectrometry (IMS). It is a key factor that is used to distinguish between and quantify ions with different masses and charges. The m/z ratio is calculated by dividing the mass of an ion by its charge and is expressed in unified atomic mass units (u) per electron charge (e). IMS is used for the detection and analysis of ions in a wide range of fields, including healthcare, biotechnology, and homeland security. IMS allows for the detection of trace molecules, such as explosives, toxins, and drugs, and can be used for a variety of applications, including breath-based diagnostics, environmental monitoring, food safety and quality control, and air quality control.
