The Difference between Frankincense and Myrrh

The Difference between Frankincense and Myrrh

It's that time of year again, when holiday songs play 24/7 on the radio and people start wondering what, exactly, frankincense and myrrh are and why they make good gifts. LECO placed these two oils in a Pegasus BT 4D to see the difference.

Frankincense (from the boswellia tree) and myrrh (from the commiphora tree) are both resins which are commonly used as perfumes and incense and have been for thousands of years. Essential oils extracted from these resins can be analyzed using gas chromatography, which is precisely what the scientists at LECO did.

By extending the analysis to a second dimension using the GC×GC analysis of the Pegasus BT 4D, even more information can be gleaned from the samples extracted from these substances. GC×GC analysis also inherently produces structured chromatograms where chemically similar analytes tend to elute in ordered bands through the GC×GC separation space. This provides context for identification and allows for rapid visual characterization of the compound classes.

Medical Diagnosis using Breath Analysis and GC×GC-TOFMS: Optimizing Data for Accurate Treatment

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 GC×GC-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.

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…“

New Pegasus® GC-HRT+ 4D for the University of Southampton

LECO’s PEGASUS® GC-HRT+ 4D will be the newest addition to the University of Southampton’s School of Chemistry, offering unique capabilities to UK researchers. Read what Professor John Langley has to say about the new mass spectrometer. “Highly advanced Southampton spectrometer to spearhead chemical research across southern region. Researchers across the south of England will analyse novel and strategically important chemistries through a new mass spectrometer at the University of Southampton.“
