Analysis of organic aerosols using a micro-orifice volatilization impactor coupled to an atmospheric-pressure chemical ionization mass spectrometer.
We present the development and characterization of a combination of a micro-orifice volatilization impactor (MOVI) and an ion trap mass spectrometer (IT/MS) with an atmospheric-pressure chemical ionization (APCI) source. The MOVI is a multi-jet impactor with 100 nozzles, allowing the collection of aerosol particles by inertial impaction on a deposition plate. The pressure drop behind the nozzle...
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...
متن کاملAtmospheric amines and ammonia measured with a chemical ionization mass spectrometer (CIMS)
We report measurements of ambient amines and ammonia with a fast response chemical ionization mass spectrometer (CIMS) in a southeastern US forest and a moderately polluted midwestern site during the summer. At the forest site, mostly C3-amines (from pptv to tens of pptv) and ammonia (up to 2 ppbv) were detected, and they both showed temperature dependencies. Aerosol-phase amines measured therm...
متن کاملDesign and performance of an atmospheric pressure ion mobility Fourier transform ion cyclotron resonance mass spectrometer.
This manuscript presents our initial results and development of a novel hybrid instrument that combines atmospheric pressure ion mobility spectrometry (AP-IMS) with Fourier transform ion cyclotron resonance mass spectrometry (FTICR-MS). Our preliminary results obtained from atmospheric pressure mobility separation of peptide mixtures combined with high-resolution FTICR mass analysis are demonst...
متن کاملAtmospheric pressure photoionization mass spectrometry.
Atmospheric pressure photoionization (APPI) is the last arrival in the family of atmospheric pressure ionization (API) methods to couple mass spectrometry (MS) to liquid-phase separation techniques. The basic idea was to further extend the fields of application of liquid chromatography (LC)-MS to those molecules that are not, or are poorly amenable, to electrospray (ESI) or APCI. The present re...
