Gas Phase Mobility Selection of Ions Prior to Mass Spectrometric Analysis
Abstract Traditionally, ion mobility spectrometry (IMS) has been used for the analysis of gas phase compounds, however, with the advent of electrospray ionization (ESI) and matrix-assisted laser desorption/ionization (MALDI) the technique's scope of analysis has greatly expanded. The powerful prospects of combining IMS and ion mobility mass spectrometry...

Liquid Phase Ion Mobility Spectrometry (LPIMS)
Abstract The present choice of analytical separation methods that occur under ambient pressure conditions are generally limited to gas chromatography(GC), liquid chromatography (HPLC), capillary zone electrophoresis (CZE) and ion mobility spectrometry (IMS). IMS is about 3 times more efficient than HPLC, 130 times more efficient than GC and almost as...

Real-Time Control for Actuators
Unmet Need: Hysteresis free ActuatorsMagnetorcheological (MR devices - also called actuators) employ MR fluids that change their viscosity upon exposure to the magnetic field. Thus these devices have great applications in civil engineering, automobile suspensions etc. The major drawback of these devices is the hysteresis behavior that they exhibit which...

Ultra-Trace Level F-element Pre-concentration Sensor/Electrode
Abstract
The ability to identify and quantitate the relative abundance of f-block elements present in environmental and industrial samples is of critical importance to national security. Current methods are slow, labor intensive and cannot be easily integrated into industrial systems. As reprocessing technologies become common within the nuclear industry...

Voltage Sweep Ion Mobility Spectrometry
AbstractIon mobility spectrometry (IMS), is a powerful tool commonly used for security applications (e.g. search for explosives, narcotics, and other trace contrabands) but it doesn’t achieve optimal separation power with both small and large ions simultaneously. Similar to the general elution problem of chromatographic experiments, small ions...
