Ion−Neutral Potential Models in Atmospheric Pressure Ion Mobility Time-of-Flight Mass Spectrometry IM(tof)MS

The Journal of Physical Chemistry A, 2006
The ion mobilities and their respective masses of several classes of amines (primary, secondary, and tertiary) were measured by electrospray ionization atmospheric pressure ion mobility time-of-flight mass spectrometry IM(tof)MS. The experimental data obtained were comparatively analyzed by the one-temperature kinetic theory of Chapman-Enskog.

Tandem ion mobility-mass spectrometry (IMS-MS) study of ion evaporation from ionic liquid-acetonitrile nanodrops

Physical Chemistry Chemical Physics, 2009
Ion evaporation is an essential step in the formation of charged ions from electrosprays, yet many aspects of the process are poorly understood. The ion evaporation kinetics of the 1-ethyl-3-methyl-imidazolium+ (EMI+) based ionic liquids (ILs) EMI-BF4, EMI-bis(perfluoroethylsulfonyl)imide, EMI-bis(trifluoromethylsulfonyl)imide and EMI-tris ...

Ion mobility spectrometry (IMS)-a chemical separation technique using an electrostatic field

Conference Record of the IEEE Industry Applications Society Annual Meeting, 2003
The author describes a chemical sensing and discrimination technique called ion mobility spectrometry (IMS), which separates ionic species in a chemical vapor by their mobility in an electrostatic field. An advantage of IMS over other techniques is speed of response.

[Photoionization ion mobility spectrometry (UV-IMS) for the isomeric volatile organic compounds].

Guang pu xue yu guang pu fen xi = Guang pu, 2015
The construction and performance study is reported for a newly developed ultraviolet photoionization ion mobility spectrometry (UV-IMS). In the present paper, an UV-IMS technique was firstly developed to detect eleven isomeric volatile organic compounds including the differences in the structure of carbon chain, the style of function group and the ...
