Currently, we’ve finalized the chromatographic conditions (shown above), and we’re working on proving the concept for
quantification using this technique for cannabis concentrates. Stay tuned to the blog and our
new cannabis landing page
for the
latest developments in our work for this and other applications. We’re always looking for opportunities for collaboration, so if
you’re interested, please let me know and I’ll get in contact with you.

MXT-35 GC-FID: Medical Marijuana Cannabinoids
Monday, May 12th, 2014 by
Jack Cochran
I’m now adding a
15m x 0.53mm x 0.50µmMXT-35
to the GC column data collection effort for cannabinoids, thanks to Ron
Stricek’s help with getting that column manufactured for me. This column is made out of metal and has the features/benefits
listed in
this brochure
. In addition to the ruggedness of the metal column and the ability to coil it tightly for smaller GC ovens,
the MXT-35 has a maximum operating temperature of 340°C versus 300°C for the Rtx-35. AND, it does a beautiful job of
separating the important medical cannabinoids when using gas chromatography.
The earlier ChromaBLOGraphy post for cannabinoids on Rxi-35Sil MS and Rtx-35 is repeated in whole below…

In a previous post, “
Don’t overestimate cannabidiol during medical cannabis potency determinations with gas chromatography.
Use stationary phase selectivity for accuracy and hydrogen for fast analysis.”,
I recommended a 15m x 0.25mm x 0.25µm
