Time-of-flight mass spectrometry - Wikipedia
QToF is capable of measuring mass to the 4th decimal place and is frequently used for pharmaceutical and toxicological analysis as a screening method for drug analogues. [24] Identification is done by collection of the mass spectrum and comparison to tandem mass spectrum libraries. [25]
