The invention provides an interface assembly for delivering an ionized analyte from an ionization apparatus into an ion mobility spectrometer. This allows analysis of biological and non-biological samples, even non-volatile solids, via differential mobility spectrometry, without fragmentation of molecules. The invention also provides portable sample analysis systems that operate at ambient pressure. Systems of the invention may be used for high molecular weight species detection, for example, drinking water contaminants, pathogenic biological agents, bio-organic substances, non-biological material, peptides, proteins, oligonucleotides, polymers, bacteria, and hydrocarbons.

Apparatus and systems for processing samples for analysis via ion mobility spectrometry

Disclosed herein are systems, methods and apparatus, for detection and identification of chemical warfare agents (CWAs) using a differential mobility spectrometer.

Systems for differential ion mobility analysis

Disclosed herein are systems, methods and apparatus, for detection and identification of analytes in a volatilized or volatilizable sample, using the mobility-based signature that is produced when the volatilized sample is passed through an ion mobility based analyzer.

Disclosed herein are systems, methods and apparatus, for detection and identification of analytes in a volatilized or volatilizable sample, using the mobility-based signature that is produced when the volatilized sample is passed through a differential ion mobility spectrometry (DMS) device.
