Of Fireworks and Tourism: GCxGC-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.

LECO Releases New Flow Modulator—FLUX™

LECO is pleased to introduce a new FLUX™ flow modulator option for routine GCxGC analysis. While LECO’s traditional thermal modulation alternative is still available and provides for the highest sensitivity, the FLUX flow modulator is a cost-effective option that makes GCxGC more accessible and easy to use.

The new flow modulator’s extraordinarily simple design is based on the principles of John Seeley et al. This straightforward design makes the flow modulator easy for the user to set up and start performing GCxGC analysis. The flow-based modulator is ideal for users who want to perform robust GCxGC analysis, but do not need the sensitivity of standard quad jet thermal modulation. Ideal samples are complex, but relatively concentrated. Our early users program has given us tremendously positive feedback.


Another advantage of the FLUX flow modulator is that it does not require cryogens to carry out GCxGC, saving the user time and resources in their lab. Method development is also simplified, as there are only two parameters for the user to manage; the flows are handled by software so the user does not have to set these themselves. The FLUX flow modulator is available for purchase with our Pegasus® BT 4D, and also for existing Pegasus BT  owners who wish to upgrade their system to a GCxGC with FLUX.

GC-MS Water Analysis: Why is TOF Better than Quadrupole?

Did you see the recent Q&A on GC-MS Water Analysis on LCGC? David Benanou, of Veolia Research and Innovation, challenged a gas chromatography—time-of-flight mass spectrometry (GC–MS-TOF) instrument (our Pegasus BT) to its limit of quantification by injecting very dilute solutions of compounds beyond their odor threshold concentration.

With the Pegasus BT, a quantitation limit of 2 pg per liter was required to obtain the full mass spectrum, whereas a GC–MS quadrupole instrument required 100 pg per liter to obtain the same result. LCGC recently sat down with David, an expert of analytical chemistry, to further discuss the advantages of TOF analysis.

How GC-MS Can Solve the Puzzle of Metabolomics

Metabolomics presents challenges for both the analytical methods used and the data reduction required to interpret the results. No single analytical technique can be used for complete characterization of the metabolome, and no metabolome has ever been completely characterized. This is where GC-MS comes in...
