10– 12 After generating considerable interest in both academic and industrial perspectives with the Synapt HDMS, many instrument developers quickly followed suit and developed their own IMS-MS platforms based on unique mobility separations, thereby adding IMS selectivity to MS for challenging systems in complex mixtures. 8, 9 Routine adoption of IMS-MS as an analytical tool began in 2006 with the commercial introduction of the Waters Synapt HDMS, the first widely marketed IMS-MS platform. 5– 7 Early IMS-MS instrumentation was generally associated with home-built instruments housed in academic settings. While standalone IMS devices are very powerful, interfacing IMS with mass spectrometry (IMS-MS) has provided even more resolution of chemical space as the complementary separations in both the mobility and mass dimensions enable exceptional levels of selectivity and sensitivity.

The resulting portable IMS devices continue to be utilized for routine detection of explosives and chemical warfare agents in military operations, sporting events, and airports. 2, 3 Over the past century, advances in instrumental design further pushed the popularity of IMS forward by enhancing its sensitivity and selectivity. 1 Due to its fast screening capabilities and high sensitivity, IMS experienced rapid growth during the 1960’s and into the subsequent decades as an atmospheric pressure device which could rapidly screen chemical vapors for trace quantities of hazardous material. Interestingly, while some may view IMS as a newer technique, its historical origins date back to 1896 in Thomson and Rutherford’s seminal work investigating the relationship between electrical conductivity and gaseous media. Ion mobility spectrometry (IMS) is the study of how ions move in gases under the influence of an electric field, or in other words the electrophoretic mobility of ions in buffer gases. Although many challenges must be addressed by the IMS community before mobility information is collected in a routine fashion, the future is bright with possibilities. Common IMS-MS applications are also discussed in this review, such as separating isomeric species, performing signal filtering for MS, and incorporating collision cross section (CCS) values into both targeted and untargeted omics-based workflows as additional ion descriptors for chemical annotation. DTIMS, TWIMS, TIMS, FAIMS and DMA), while addressing the strengths and shortcomings associated with each. In this Critical Insight, we aim to clarify some common misconceptions for new users in the community pertaining to the fundamental concepts of the various IMS instrumental platforms ( i.e. However, the continual development of novel IMS methods has generated some level of confusion regarding the advantages and disadvantages of each. IMS separations occur on a millisecond timescale, and therefore can be readily nested into traditional GC and LC/MS workflows. Interfacing IMS with mass spectrometry (IMS-MS) provides additional analytical power as complementary separations from each technique enable multidimensional characterization of detected analytes.
