  (199.3KB) This one page documents shows the temperature programs used on
  the two column types.
  SRI has had to switch from the 15 meter MXT500 column to a 30 meter MXT502 column because the MXT500 column is no longer produced as of 2020. 
  The new MXT502 column is better in some ways.

  These chromatograms show olive oil, MCT oil and the cannabinoids
  on the 15meter MXT500 .25micron column.

Download

• Cannabinoids in MCT oil using SRI 310Edibles GC configuration
  (887.0KB) These chromatograms show how the SRI 310 Edibles GC uses its
  stop-flow and backflush capability to reject the MCT and hiogher boiling oils while
  still measuring the cannabinoids ( CBD, THC and CBN ).
  The pre-column in this GC configuration cataches the higher boiling molecules
  and then backflushes them to vent so they never arrive at the main column.

Download
