Carbon compounds form the basis of all life on Earth and the carbon-nitrogen cycle provides some of the energy produced by the Sun and other stars.
Moreover, carbon has the highest melting/sublimation point of all elements.
It is produced, however, in the interior of stars in the horizontal branch, where stars transform a helium core into carbon by means of the triple-alpha process.

Carbon occurs in all organic life and is the basis of organic chemistry.
This nonmetal also has the interesting chemical property of being able to bond with itself and a wide variety of other elements, forming nearly ten million known compounds.
Recently living materials the biobased component have Carbon in them while fossil materials derived from petroleum no longer have this weakly radioactive carbon isotope.
There is a correction made for the increased nitrogen blank from the glove box gas.
Atomic weight 12.01, Atomic Number 6, Melting Point 3550 C, Boiling Point 4,827 C.
Since the heat conductivity depends upon it’s composition, the mixture of remaining gasses is sensed. Later the CO2 is removed and finally only N2 remains. The instrument is calibrated using various standards from the NIST.
Thus all three elements can be determined in one run from the same sample selection. It is always best that the analyst knows all elements present (the molecular formula).
