Detecting Trace Explosives and Formulations Using Laser Electrospray Mass Spectrometry
Mass analysis using laser electrospray mass spectrometry (LEMS) is demonstrated for the detection of trace samples of explosives at atmospheric pressure directly from a substrate. A non-resonant femtosecond duration laser pulse vaporizes native samples at atmospheric pressure for subsequent electrospray ionization and transfer into a mass spectrometer. LEMS was used to detect < 1 µg of 2,3-dime...
متن کاملExplosive-trace Detection System Using Mass Spectrometry
OVERVIEW: The terrorist attacks of September 11th, 2001 in the USA have radically changed the awareness of society towards both domestic and international security. These days, as a result of the destabilization of world affairs, terrorist attacks involving explosives or harmful chemical substances are happening all over the world, and the barbarity of such attacks has been worsening. In respon...
متن کاملOptimized thermal desorption for improved sensitivity in trace explosives detection by ion mobility spectrometry.
In this work we evaluate the influence of thermal desorber temperature on the analytical response of a swipe-based thermal desorption ion mobility spectrometer (IMS) for detection of trace explosives. IMS response for several common high explosives ranging from 0.1 ng to 100 ng was measured over a thermal desorber temperature range from 60 °C to 280 °C. Most of the explosives examined demonstra...
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...
متن کاملInorganic trace analysis by mass spectrometry
Mass spectrometric methods for the trace analysis of inorganic materials with their ability to provide a very sensitive multielemental analysis have been established for the determination of trace and ultratrace elements in high-purity materials (metals, semiconductors and insulators), in different technical samples (e.g. alloys, pure chemicals, ceramics, thin films, ionimplanted semiconductors...
