Ion Mobility Spectrometry (IMS) is an analytical technique used to detect trace amounts of chemical substances, particularly volatile organic compounds. The process begins by ionizing sample molecules, generating ions that enter a drift tube maintained at low pressure, forming a cloud. Under the influence of a uniform electric field, ions move within the tube and collide with buffer gas molecules. The ion migration velocity is influenced by factors such as size and charge, forming a unique migration spectrum.

At the end of the tube, a detector records the arrival time of ions, generating a unique ion mobility spectrum. This spectrum serves as a fingerprint of the chemical composition, and analysis personnel can identify substances in the sample by comparing it with known spectra in a database.

Ion Mobility Spectrometry is known for its high sensitivity and rapid analysis, making it useful in the security field for detecting explosives and drugs, as well as in environmental monitoring and analytical chemistry. Its efficiency and wide applicability make it an important tool in multiple scientific and industrial fields.
