A chemical modifier is added to the drift gas that interacts selectively with a targeted molecule in at least one component of the sample in a drift tube. The component may be impurities and/or interferences in the sample whereby the chemical modifier enhances sample resolution by shifting the components drift times. In addition, reagents can be added to the sample prior to, during, or after ionization to form a complex with selected components in the sample. In addition, one or more internal and/or external standard can also be added to the sample as a calibration for the measurement."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for chemical and biological sample separation","description":"The present invention describes a method and apparatus for separating chemical and/or biological samples based on selective ion-molecular interactions in the gas phase.
