Dispersion characteristics in order to improve the analysis of the sample, the sample dissociation and / or mobility-based apparatus and method using a pressure control

摘要

The present invention, in general, the system of ion mobility base for sample analysis method and apparatus. Sample dissociation; For example, the dispersion characteristics invention, and / or, but are not limited to using the variation in sample processing, such as variation in the flow channel / filter field conditions during sample collection, filtering, detection, measurement, to provide an improvement of identification and / or analysis (collectively referred to as "analysis"). Such conditions include, but are not limited to, pressure; intensity of the electric field, the duty cycle and / or frequency; temperature; humidity field voltage amplitude, frequency and / or duty cycle; size and detector bias voltage / or polar; may be included and / or polarity of the filter size field compensation voltage and / or.
