What is the mass range of the MS-200 mass spectrometer?
The MS-200 has a mass range of 0-1000 Daltons, and in practice this covers the range of masses for most organic gases that are the principal application for this analyser. In principle, a suitable ToF spectrometer is capable of measuring masses out to several hundred thousand Daltons. In practice, the practical mass range of a ToF analyser is limited by three major factors: • The ability to create high mass ions without fragmentation, • The ability to convert high mass ions to electrical signals at the detector, and • The ability to transport heavier non-volatile species into the ion source Energetic ionisation processes such as electron impact result in significant fragmentation of the target molecules, producing a characteristic spectrum from a compound containing several peaks. Such a fingerprint spectrum can however be used to good effect to help clarify molecular structure, and also for unambiguous identification of the compound.
