Development of a Miniature Mass Spectrometer and an Automated Detector for Sampling Explosive Materials
The development of a robust ionization source using the counter-flow APCI, miniature mass spectrometer, and an automated sampling system for detecting explosives are described. These development efforts using mass spectrometry were made in order to improve the efficiencies of on-site detection in areas such as security, environmental, and industrial applications. A development team, including t...
متن کاملMiniature time-of-flight mass spectrometer using a flexible circuitboard reflector
An innovative design for a miniature time-of-flight mass spectrometer has been developed employing several newly designed components. These include: (1) a gridless, focusing ion source allowing for the use of very high extraction energies in a maintenance-free design, (2) a new method of construction for an ion reflector using rolled flexible circuitboard material, and (3) an improved center-ho...
متن کاملRapid hydrocarbon analysis using a miniature rectilinear ion trap mass spectrometer.
A miniature ion trap mass analyzer was applied to the analysis of traces of hydrocarbons and simple heteroatomics in the vapor phase and in aqueous solution. Vapors of acetone, acetic acid, acetonitrile, benzene, butanethiol, carbon disulfide, hexane, dichloromethane, naphthalene, toluene and xylenes were detected and quantified using solid sorbent trapping and, in some cases, by passage throug...
متن کاملA miniature mass spectrometer for chemical and biological sensing
An experimental study has been carried out using a Miniature Quadrupole Mass Spectrometer (MicroQuad) for gas analysis. Conventional quadrupole rods have been replaced with a micromachined mass filter made from silicon with Au metallised specially drawn glass fibres of length 30 mm and diameter 0.5 mm. A standard hot filament ion source and both Faraday detection and a channel electron multipli...
متن کاملDesign, Construction and Calibration of a Laser Ionization Time-of-Flight Mass Spectrometer
A time-of-flight mass spectrometer (TOF-MS) developed in our laboratory at Isfahan University of Technology is described here. The TOF-MS instrument uses laser as the ionization source which provides an opportunity to investigate the ions formed in laser ablation or desorption. The TOF-MS has an ionization chamber containing an accelerator and an ion lens to focus the ions into a one meter line...
