Reference materials for emerging and legacy organic contaminants

Ongoing
The Biochemical and Exposure Sciences Group (BSEG) produces environmental matrix and solution-based reference materials to support the environmental measurement community. These materials assist in identifying legacy organic contaminants such as polychlorinated biphenyls (PCBs)that were commonly

Reference Materials for Plastic Pollution Measurement Science

Ongoing
Microplastic reference materials of different sizes and shapes are required to support environmental studies. Smaller size classes, particularly between 1 µm and 500 µm, are needed to develop microplastic extraction methods, to identify additives in microplastics, and to create in-house spectral

Resonating Platforms for Microbial, Environmental, and Materials Sensing

Ongoing
The high sensitivity of resonating piezoelectric crystals to surface perturbations has led to quartz crystal microbalances (QCMs) being widely used to measure changes in mass of thin films and adhered nanoparticles or cells. This project proceeds beyond this traditional sensing approach with quartz

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

Tandem Mass Spectral Library

Ongoing
Intended Impact Modern mass spectrometers commonly generate ions by electrospray mass spectrometry which are separated and then fragmented by collisional dissociation. This process yields fragment ion ‘fingerprints’ (or mass spectra) that are widely used to identify the individual components in a
