چکیده
The principles of time-of-Ñight mass spectrometry (TOFMS) are described with a view to understanding the strengths and weaknesses of this method of mass analysis in the context of current applications of mass spectrometry and the more familiar scanning instruments. Fundamental and instrumental factors a†ecting resolving power, sensitivity and speed are examined. Methods of gating ion populations and the special requirements in the detection and digitisation of the signals in the TOFMS experiment are discussed.

متن کاملRecent advances in secondary ion mass spectrometry of solid acid catalysts: large zeolite crystals under bombardment.
This Perspective aims to inform the heterogeneous catalysis and materials science community about the recent advances in Time-of-Flight-Secondary Ion Mass Spectrometry (ToF-SIMS) to characterize catalytic solids by taking large model H-ZSM-5 zeolite crystals as a showcase system. SIMS-based techniques have been explored in the 1980-1990's to study porous catalyst materials but, due to their lim...

متن کاملForensic Identification of Explosives by Mass Spectrometry and Allied Techniques.
In forensic analysis of explosives, analytical methods are required that combine good separation characteristics with highly specific and sensitive detection. Two novel techniques, liquid chromatography/mass spectrometry (LC/MS) and tandem mass spectrometry (MS/MS) have such specifications. These are now well-established analytical techniques for separation and identification of mixtures and fo...
