From PFAS in groundwater to elemental characterization of soil and waste, modern environmental monitoring often requires more than a single analytical approach. LECO delivers both high-performance mass spectrometry and precise elemental analysis instrumentation, enabling labs around the world to get a more complete picture of their samples. Laboratories can identify trace contaminants while also quantifying the bulk composition of environmental samples. Together, these tools provide the complete analytical insight needed to assess and protect ecosystem health.
When trace contaminants are lost in complex, “dirty” samples, standard chromatography falls short. LECO’s GC-TOFMS and GCxGC-TOFMS platforms provide the separation power needed for the most challenging environmental matrices.
To put organic data into context, you must first quantify the sample’s bulk chemistry. LECO’s combustion analyzers and thermogravimetric analysis (TGA) systems provide high-throughput quantification of primary elemental constituents.
Discover what’s in your sample. No matter your mission, you can rely on LECO instruments to provide the data required for your scientific and regulatory goals. Explore our library of application notes and technical resources to see our solutions in action.

“For the past 20 years, LECO GCxGC platforms have been the shining star of our laboratory and provided previously unattainable and novel insights into the source, transport, and fate of organic contaminants in the environment. These robust and responsive instruments have helped us investigate the efficacy of dispersants during the 2010 Deepwater Horizon disaster, non-target searching of dumped DDT waste along the CA coastline and characterize the toxic components of burnt plastic from the 2021 Express Pearl fire.
Our best work has relied on the synergy of complimentary data produced by LECO’s GCxGC-FID, Pegasus 4D, and Pegasus HRT 4D High Resolution TOF mass spectrometers. Combined with LECO’s excellent technical support, software development, and customer service, we cannot imagine a better product and company.”

“We have been working with LECO’s GC×GC-TOF instruments since 2004, beginning with Pegasus IVD and even the first prototypes of the high resolution mass spectrometers. My colleagues are fond of the TOF information capacity, reliability, speed and especially software features. Accurate mass measurements, GC×GC option and now three methods of ionization allow working with the most complex samples and achieving reliable results. We have been working mainly in the field of environmental analysis. Besides development of the methodology of non-target analysis, studies of the rain water from France, Russia, and Chile, snow from the USA, Russia, Finland, the Baikal Lake, and the Arctic islands, cloud water from France, soil and water from Montenegro and the USA. A solution to the contamination problem of the Gray Whales are also worth mentioning. LECO instruments were also successfully used in the studies of drinking water preparation and disinfection by-products formation as well as in the research dealing with cultural heritage, including Stradivarius violins, ancient Egyptian mummies and Chinese scrolls. Over 50 papers in the top international journals were published on these issues. I would like to specially mention that every year brings some interesting novelties increasing the power of the LECO mass spectrometers. This year we got the two newest models of Pegasus BTX4D and Pegasus HRT+4D instruments. We are looking forward with optimism to work with new samples related to Chinese art, drinking and waste water purification, and plants used in Chinese traditional medicine.”
