Design, 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...
متن کاملConstruction and performance test of a multiplexed multistage (MS(n)) time-of-flight mass spectrometer.
A time-of-flight mass spectrometer equipped with two reflectrons was constructed for multiplexed photodissociation tandem mass spectrometry of peptide ions generated by matrix-assisted laser desorption ionization. A linear reflectron was used for high-resolution selection of a precursor ion while a quadratic reflectron was used for product ion analysis. With the photoexcitation of a precursor i...
متن کاملSoil volatile analysis by proton transfer reaction-time of flight mass spectrometry (PTR-TOF-MS)
We analyzed the volatile organic compounds (VOCs) emitted from different soils by using the PTR-MS-TOF technique under laboratory conditions and compared them with soil chemical biochemical activities. The emitted VOCs were related to soil microbial biomass, soil respiration and some soil enzyme activities so as to evaluate if size and activity of soil microbial communities influenced the soil ...
