"Selectivity: When, Where, and How to Use It!" by Diane Turner at LECO’S GC×GC Workshop & Symposium

At LECO’S GC×GC Workshop & Symposium, Dr. Diane Turner gave a talk about "Selectivity: Where, When, and How to Use It!" The talk covers techniques for sample analysis, selectivity in choosing the right technical setup (column choice, inlet parameters etc.), and also data analysis optimisation.

Dr. Diane Turner is Senior Consultant & Director, Anthias Consulting Ltd., Consultant, The Open University, and President-Elect, Analytical Division, RSC.

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

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.

The analysis was conducted by taking water samples from three different places along the shoreline; the fireworks launch location off the pier, as well as two local beaches close to the launch site. This was done on July 2nd as well as on July 4th (an hour after the fireworks show) to provide an accurate measurement. LECO’s Pegasus HRT+ 4D system was used to analyse the water samples, which offers comprehensive two-dimensional gas chromatography coupled to high-resolution time-of-flight mass spectrometry (GC×GC-HRTOFMS). GC×GC-HRTOFMS proved a powerful tool for exploration as it provided a full non-targeted analysis of the water samples before and after the fireworks show, clearly demonstrating the chemical differences between the two. GC×GC-HRTOFMS was also able to pinpoint contributions to the environmental pollution that occurred as a result of these pyrotechnic displays and the increased human traffic near the water sampling sites.

So what happened to the water quality of Lake Michigan from the increased tourism and fireworks? The results may surprise you…

Mass spectrometry and the history of GC-TOFMS by Alan Griffiths

 Non-targeted analysis, data science and innovation have synchronised to underpin the next generation of separation science analysis in mass spectrometry. LECO UK’s separations science product specialist Alan Griffiths explains.

“Ideas often spark one another, and chain reactions occur. As with chemical reactions, ideas can remain contained in relatively small areas before gradually spreading outward. California’s Silicon Valley is a focal point for technology. For mass spectrometry (MS), the UK’s city of Manchester is a focal point. Manchester is where the first commercial mass spectrometer built outside of the US was produced…“

e-Food Lab International // Interview with Ralf Löscher

Ralf Löscher speaks about the latest technologies, as well as many years experience LECO has in the field of TOFMS instrumentation. The special focus of this interview refers to the food industry and the special benefits LECO offers to this market.

“In the field of chromatographic separation science technology, LECO offers GC coupled to time-of-flight (TOF) mass spectrometry (MS). This includes one-dimensional as well as two-dimensional chromatography (GC×GC), which increases chromatographic resolution and sensitivity. In addition, our latest technology is competitively priced in relation to triple quadrupole alternatives. Furthermore, GC-TOF-MS technology is basically unbeatable for the analysis of residues in complex matrices such as teas, spices, oily products, but also baby food.“
