The flight paths of the ions are altered by varying the applied fields which ensures their separation from one another on the basis of their mass-to-charge (m/z) values. Rapid Commun. Unlike other detectors, the LC eluent carrying the separated analytes is not allowed to flow into the mass spectrometer. MS2 RNA is a type of small non-coding RNA (sncRNA) found in bacteria. Epub 2022 Jul 20. While Q1 and Q3 are operated as mass analyzers to scan over a mass range or to monitor an ion of specific m/z value, the collision cell is used to fragment the precursor ions isolated in Q1 by subjecting them to high energy collisions with a neutral gas, such as argon, helium or nitrogen. At the same time, its resistance is more towards inactivation than the enveloped viruses.
