Determining MOSH/MOAH with GCxGC-TOFMS

April 23, 2020

Contamination of food by mineral oil hydrocarbons such as mineral oil saturated hydrocarbons (MOSH) and mineral oil aromatic hydrocarbons (MOAH) has been a growing concern since 2012, when the European Food Safety Authority flagged them as a potential health concern. While the main concerns are bioaccumulation from MOSH and the carcinogenicity of MOAH, data on consumer exposure is incomplete. Prevailing wisdom suggests we make every effort to minimize MOSH/MOAH contamination, however, MOSH/MOAH analysis is not easy. Though there is a standard European GC-FID method, countries are still discussing GC-MS standard methods for MOSH/MOAH analysis. The existing methods struggle to deconvolute the various hydrocarbons.

Enter the LECO Pegasus® BT 4D with GCxGC-TOFMS.

Medical Investigation using Breath Analysis and GCxGC-TOFMS: Optimizing Data for Accurate Treatment

March 19, 2020

At our ASMS breakfast seminars, Jean-François (Jef) Focant, Head of the Department of Chemistry and Director of the Organic and Biological Analytical Chemistry group at the University of Liège, Belgium, spoke about using our Pegasus® BT 4D and Pegasus® GC-HRT 4D for GCxGC-TOFMS on the breath of asthma patients to improve asthma treatment*. Before diving into the blood and sputum, Jef first educated us on the importance of optimizing your data.

Our Lab at Your Front Door

February 26, 2020

LECO understands that taking time away from your lab to visit our headquarters in Saint Joseph, Michigan, is not always a possibility. Travel alone is a hassle, much less the downtime of being away from your lab and the expense of all of the arrangements. Unfortunately, even our bench-top Pegasus® GC-TOFMS is a bit too large to slip into a carry-on for an in-person experience. Webinars and virtual demonstrations have come a long way in bringing new technology closer for your inspection, but there's nothing like getting to kick the tires and have a hands-on experience to really know what you could be adding to your lab. What’s a busy lab manager to do?

ASMS in Review: Frank Dorman, Penn State

August 20, 2019

Frank Dorman, an Associate Professor of Biochemistry and Molecular Biology at Penn State University, spoke at our ASMS breakfast seminar about his experience using our Pegasus BT 4D benchtop GCxGC-TOFMS to analyze environmental contamination in the Susquehanna river. Due to the increasing chemical complexity of the environment, GCxGC-TOFMS with its Non-Targeted compound analysis is the ideal technology for these intricate samples.

Take Your GC-MS Analysis One Step Further

August 1, 2019

What if you could take your GC-MS analysis one step further by easily adding a second dimension of separation? Our new FLUX™ GCxGC flow modulator uses a diverting flow technique (rather than industry-standard thermal modulation), eliminating the need for costly cryogens, and making GCxGC more cost-effective and routine to the everyday analyst.

Of Fireworks and Tourism: GCxGC-HRMS Analysis of Summer Impacts on Lake Michigan Water Quality

July 3, 2019

Fireworks are a staple of America’s Independence Day celebrations. It is estimated that 16,000 fireworks displays are held in the United States each year and American consumers will spend more than $1 billion in firework sales to mark the holiday! Beyond a big bang and bright lights, how do these fireworks affect the environmental world around them? LECO’s world headquarters are located in Saint Joseph, Michigan, a beach town on Lake Michigan where fireworks are a prominent backdrop to the 4th of July celebration. Last summer, our applications lab thought it would be a worthwhile and interesting experiment to test the water surrounding the firework launch spot to explore if there were any short-term environmental impacts. The influx of tourists to the Lake Michigan beaches during the holiday is sure to contribute chemicals from personal care products (sunscreen and insect repellent) to the water as well. Evaluating these potential contaminants surrounding the July 4th holiday was the objective of this study.
