Standards Development to Ensure Reliable Breath Analysis in the Field

Ongoing
Numerous volatile organic compounds (VOCs) have been identified in human breath. These compounds can be produced by the body or by organisms in the body (e.g., bacteria or viruses) and provide a non-invasive window into human health. Inexpensive point-of-care devices are being developed to diagnose

Ambient and Atmospheric Pressure Mass Spectrometry

Ongoing
Surface and Trace Chemical Analysis Group employs a range of commercial pneumatically-assisted electrospray ionization (ESI), atmospheric pressure chemical ionization (APCI), and atmospheric pressure photoionization (APPI) sources for traditional mass spectrometric chemical analysis, identification

Open Port Liquid Interface Mass Spectrometry

Ongoing
Rapid screening for chemical traces of explosives and narcotics is widely used to support homeland security and law enforcement. These target compounds span a range of physicochemical properties from organic to inorganic, with preferential ionization pathways in both negative and positive mode
