MOBILITY BASED APPARATUS AND METHOD USING DISPERSION CHARACTERISTICS, SAMPLE FRAGMENTATION, AND/OR PRESSURE CONTROL TO IMPROVE ANALYSIS OF SAMPLE

摘要

PROBLEM TO BE SOLVED: To provide an ion mobility-based system, method and device for analyzing samples.;SOLUTION: The present invention provides improving sample collection, filtration, detection, measurement, identification and/or analysis (collectively "analysis") using, for example: dispersion characteristics; sample fragmentation; and/or variations in sample processing such as, without limitation, variations in flow channel/filter field conditions. Such conditions may include, without limitation: pressure; temperature; humidity; field strength, duty cycle, and/or frequency; field voltage amplitude, frequency and/or duty cycle; detector bias voltage magnitude and/or polarity; and/or filter field compensation voltage magnitude and/or polarity.;COPYRIGHT: (C)2011,JPO&INPIT
