About
Dr. Rachel V. Bennett is a pioneer in the development of ambient ionization mass spectrometry, with a particular focus on enabling the analysis of complex, non-planar surfaces. Her most significant contribution is the invention of the Robotic Plasma Probe Ionization system (RoPPI-MS), a transformative technology that couples a robotic arm with a plasma-based ionization source. This system, detailed in her highly cited 2014 paper, uses an acupuncture needle to sample surfaces directly, allowing for the chemical imaging of objects with irregular geometries—such as artifacts, biological tissues, or manufactured parts—that are inaccessible to conventional flat-surface imaging techniques. By automating the sampling and ionization process, RoPPI-MS dramatically enhances reproducibility and throughput for spot analysis and imaging. While her citation count reflects the niche but critical nature of her work, its impact is profound, opening new avenues in forensic science, clinical diagnostics, and cultural heritage preservation. Bennett’s research exemplifies a creative fusion of robotics and analytical chemistry, solving a fundamental limitation in mass spectrometry and inspiring a new generation of automated, surface-sampling technologies.
