Using Fourier-Transform ion gate modulation technique, we compare the ability of the tri-state ion shutter (3S-IS) to the two-state ion shutter (2S-IS) in separating three pairs of isomeric peptide including 1.Gly-Arg-Gly-Asp-Ser (GRGDS) / Ser-Asp-Gl

We evaluated the effect of four different waveform profiles (Square, Sine, Triangle, and asymmetric Sawtooth) on the accuracy of collision cross section (CCS) measurements using traveling wave ion mobility spectrometry (TWIMS) separations in structur

Ion mobility spectrometry employing structures for lossless ion manipulations (SLIM-IMS) is an attractive gas-phase separation technique due to its ability to achieve unprecedented effective ion path lengths (>1 km) and IMS resolving powers in a smal

Vapor assisted mobility shift measurements were made with atmospheric pressure drift-tube ion mobility-mass spectrometry (IM-MS) to determine the thermodynamic properties of weakly bound ion-molecule clusters formed from protonated phenylalanine and

Combining experimental data with computational modeling, we illustrate the capacity of selective gas-phase interactions using neutral gas vapors to yield an additional dimension of gas-phase ion mobility separation. Not only are the mobility shifts a

For time dispersive ion mobility experiments detail control over the mechanism of ion beam modulation is necessary to establish optimum performance as this parameter greatly influences the temporal width of the ion beam arriving at the detector. When

Through vapor modification of the counter-current drift gas in an atmospheric pressure drift tube ion mobility spectrometer (IMS), we demonstrate measurement of gas-phase association enthalpies and entropies for select proton-bound heterodimers forme
