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.
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.

Analysis of Fats in Food Products with GC-TOFMS
Reporting the fat content of food on packaging material is required for many products. For this reason, the ability to detect and distinguish different types of fats is important. The AOAC has an official method, Method 996.06, for the detection of fats (total, saturated, and unsaturated) that uses GC paired with FID to separate fatty acids, derivatized with methylation.

Non-targeted screening in forensics, a discussion of method development and screening of forensic samples using GCXGC-TOFMS
Joining us from William and Mary, Dr. Katelynn A. Perrault Uptmor, PI of the Nontargeted Separations Laboratory , present her work of screening samples using comprehensive two-dimensional gas chromatography with time-of-flight mass spectrometry (GCXGC-TOFMS) in forensic applications as novel types of evidence appear. Dr. Perrault Uptmor highlights initial approaches to method development for new samples and show recent applications related to chemical profiling of deposited fingermarks, organic gunshot residue and decomposition odor. She also discusses the implications of GCXGC-TOFMS sample visualization in the context of expert testimony for communicating screening processes in forensic casework within the courtroom.
