Atmospheric pressure ion guides are provided. The atmospheric pressure ion guides can include a multi-ring electrode structure connecting a larger opening to a smaller opening and having a series of ring electrodes with decreasing diameter and voltage going from the larger opening to the smaller opening. The electrodes can be made from stainless steel or other suitable conductive material. The multi-ring electrode structure can be contained in a housing, such as a housing made from polyetheretherketone or other suitable thermosetting polymer. The atmospheric pressure ion guide can focus ions from an ion source for use with ion detection devices such as an ion mobility spectrometer or a mass spectrometer. Methods of using the atmospheric pressure ion guides are provided, for example to focus a plurality of ions to be injected into an ion detection device. The atmospheric pressure ion guides can increase the signal intensity of the ion detection device.

Atmospheric pressure ion guide

A system for detecting a chemical substance of interest among a plurality of different chemical substances comprises an inlet, an ionization module, a high-field asymmetric waveform ion mobility spectrometry (FAIMS) cell, and optionally a detector. A focussing module and/or a flow control gas supply can be provided. The system has example applications for molecules including &#x394;-9-tetrahydrocannabinol (THC), its metabolites and/or other substances of interest from a breath of a subject or from a breath sample obtained from a subject.
