LECO Solutions for TOF-MS

As a venerable pioneer in analytical instrumentation, LECO Corporation has been at the forefront of scientific innovation since 1936. Among our most sophisticated offerings is the time-of-flight (TOF) technology, a cornerstone of modern mass spectrometry. This ingenious method allows for the precise measurement of an ion’s mass-to-charge ratio by determining the time it takes for the ion to travel a known distance.

LECO’s time-of-flight instruments represent the pinnacle of analytical prowess, offering unparalleled speed, sensitivity, and resolution. By harnessing the power of TOF technology, our instruments enable researchers and scientists to unlock the mysteries of complex chemical mixtures with extraordinary accuracy. From environmental analysis to food safety testing, LECO’s TOF systems empower laboratories worldwide to achieve results they can trust, continuing our long-standing tradition of analytical excellence that spans nearly nine decades.

• Non-Targeted Screening in Food: Boosting Food Analysis using GC×GC-ToF MS

  Joining us from the University of Messina, Mariosimone Zoccali, Assistant Professor of Analytical Chemistry, present on 'Boosting Food Analysis Using GCxGC-ToFMS. In his talk, Prof. Zoccali explores the pioneering applications of Comprehensive Two-Dimensional Gas Chromatography coupled with Time-of-Flight Mass Spectrometry in the analysis of extra virgin olive oil (EVOO), measured on our newly released Pegasus BTX GCxGC-ToF MS. He shows how this advanced technique provides insights in both targeted and non-targeted analyses , offering deeper understanding into EVOO's chemical profiles. Dr. Zoccali highlights how GCxGC-ToF MS enhances the detection of contaminants and key compounds, such as antioxidants and sterols, which are essential for assessing quality, authenticity and flavor.
