LECO Releases New Flow Modulator—FLUX™

January 23, 2019

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.

How GC-MS Can Solve the Puzzle of Metabolomics

November 14, 2018

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...

Why Limit Your Analysis with MS/MS?

June 6, 2018

In your application work, you need the power to analyze even the most complex samples. MS/MS can restrict your analysis due to its targeted nature, giving you “tunnel vision” and causing you to potentially miss key analytes. Our Pegasus BT 4D is the solution to coelution. You won’t limit your analysis with GCxGC-TOFMS as it provides the complete picture while also transforming your lab’s productivity. You’ll save time, improve your sample throughput, and increase confidence in your analyte identification, without missing a thing.

Vendor Seminar
A Key Player in Your Tool Box for Medical Applications
Presented by Jean-François Focant, University of Liege
Tuesday, May 15th, 15:45-16:45 pm | Room 300

GC×GC-(HR)TOFMS has reached maturity and can now be used to solve routine complex separation science issues. This is particularly true for several medical applications that require non-targeted screening of biological markers of interest either for population screening or better understanding of specific biological pathways. However, this increase of analytical resolution comes with an increase of system and data complexity, creating a critical need for adequate method optimization and quality control (QC) protocols. Learn more at our seminar, where examples of the use of thermal desorption (TD) and solid-phase microextraction (SPME) GC×GC-(HR)TOFMS will be highlighted in the field of respiratory diseases.

Investigating Cannabis with GCxGC-TOFMS

April 23, 2018

Cannabis, and its use for medical or recreational purposes, has been a hot topic in both the political and social realms in recent years. From a medical standpoint, these chemicals may help treat a number of illness and symptoms, such as chronic pain, multiple sclerosis, epilepsy, anxiety, and cancer through ingestion, inhalation, or topical application. Cannabis is a complex mixture made up specifically of cannabinoids, terpenes, flavonoids, and other chemicals related to delta-9-tetrahydrocannabinol (THC) and cannabidiol (CBD). The relationship between terpenes and cannabinoids, and how they work together to create a therapeutic experience is termed the “Entourage Effect”.

Analyzing the total composition of cannabis is an important aspect of determining its potency and medical effectiveness. The terpenes in its chemical makeup are what give cannabis its aromatic and flavor profile, and as True Terpenes describes, “It is the terpenes in cannabis which modulate (modify or control) the effect that the cannabinoids in each sample will have on the user, this is why strains of cannabis effect each user uniquely. For example, if you have 2 different types of cannabis and both have 15% THC, but one gives you energetic effects and one gives you sedative effects, this is largely due to the different terpene profiles.” Therefore, better understanding the chemical framework of cannabis can aid in determining how certain strains may work.
