Mexico City, Mexico – This month, Dr. Omar Amador Muñoz and his research team at National Autonomous University of Mexico (UNAM) begin a new project searching for cancer biomarkers in breath. Analysis of volatile organic compounds in breath has the potential to be a fast, easy, and noninvasive way to diagnose disease. However, it is a challenging endeavor because it requires extremely fast measurement, ability to detect a wide range of species, and low detection limits. The UNAM team is using a Vocus 2R CI-TOF equipped with switchable reagent-ion chemistry, a research-grade breath inlet, and customized TOFWERK BREATHE software designed to streamline sampling from patients.
In addition to studying respiratory disease, the UNAM research group is using their Vocus for long-term and mobile atmospheric sampling to better understand sources and transport of air pollutants in Mexico City.
