Meaning and Definition
A mass spectrometry technique that determines the mass-to-charge ratio of ions by measuring the time they take to travel a fixed distance in a field-free region.
In this method, ions are accelerated by an electric field and then allowed to drift through a vacuum; lighter ions reach the detector faster than heavier ones, enabling precise mass analysis with high resolution and speed.
Dialectal Variation

FAQ
Frequently Asked Questions
TOF-MS stands for Time-Of-Flight Mass Spectroscopy, a technique used for mass analysis.
It separates ions based on their time of flight through a vacuum, rather than using magnetic or electric fields for deflection.
It is widely used in drug discovery, environmental monitoring, forensic analysis, and biomolecular research like proteomics and metabolomics.
Yes, it is effective for large molecules such as proteins and polymers due to its high mass range and resolution.
