The invention relates generally to ion mobility based systems, methods and devices for analyzing samples and, more particularly, to sample pre-separation and amplification.

Methods and apparatus for enhanced ion based sample detection using selective pre-separation and amplification

The invention relates generally to ion mobility based systems, methods and devices for analyzing samples and, more particularly, to sample detection using multiple detection and analytical techniques in combination.

Methods and apparatus for enhanced sample identification based on combined analytical techniques

In a system for chemical analysis, an RF-driven plasma ionization device including a pair of spaced-apart and plasma-isolated electrodes, the electrodes are connected to a power source wherein the electrodes act as plates of a capacitor of a resonant circuit, the gas electrically discharges and creates a plasma of both positive and negative ions, and the voltage is applied as a continuous alternating waveform or as a series of pulses, such as a packet waveform.

Capacitive discharge plasma ion source

The invention relates generally to ion mobility-based systems, methods and devices for analyzing samples.

Mobility based apparatus and methods using dispersion characteristics, sample fragmentation, and/or pressure control to improve analysis of a sample

An apparatus for identification of chemical species by measurement of mobility as a function of high electric field and for generating unique compound-dependent signatures based on ion mobility at a plurality of peak RF voltages for a given compensation. The resulting detection data is compared against a library of data in order to identify a detected chemical species.

System for collection of data and identification of unknown ion species in an electric field

Method and apparatus for field ion mobility spectrometry for identification of chemical compounds in a sample by trajectory of sample ions in a transverse electric field.
