Surface Desorption Ambient Mass Spectrometry

Ongoing

The Surface and Trace Chemical Analysis Group maintains a range of research avenues into the characterization, analysis, and optimization of various commercial and in-house developed surface desorption ion sources. These research avenues also aim to advance our fundamental understanding of the...

Synthetic Biology

Ongoing

New measurement methods and tools are required for biology to emerge fully as an enabling, practical platform for engineering. The Cellular Engineering Group works to provide a foundation of measurement assurance to support the control and rational design of biological function. Through state of the...

US TAG for ISO/TC 334: Reference Materials

Ongoing

Get involved: Interested US Stakeholders may participate in the US TAG at no cost. Membership provides access to all ISO/TC 334 and US TAG documents, including standards under development. Please click here to join or renew your membership. Contribute to standards development : Please click here to...

Thermal Desorption Ambient Mass Spectrometry

Ongoing

The Surface and Trace Chemical Analysis Group is involved in a number of research avenues for the rapid screening of wipe-collected samples for the security and forensic chemistry fields. Similar to the widely-deploy ion mobility spectrometry (IMS) systems for screening, this is accomplished through...

Time-of-Flight Secondary Ion Mass Spectrometry

Ongoing

ToF-SIMS is an imaging mass spectrometry (MS) technique that allows us to obtain isotopic, elemental, and molecular information from the surface of solid samples. A pulsed, energetic “primary” ion beam bombards the surface and induces a collision cascade, liberating “secondary” ions that are then...

Vitamin D Metabolites Quality Assurance Program (VitDQAP)

Completed

Interlaboratory comparison studies of the VitDQAP supported the reliability of vitamin D measurements, including determination of 25-hydroxyvitamin D2, 25-hydroxyvitamin D3, and 3- epi-25-hydroxyvitamin D3 in human serum and plasma. Results from the comparison studies helped participants to make...
