Ethane Calibration Standard 10 ppm
Ethane Calibration Standard is a gas mixture containing 10 ppm ethane in nitrogen, used for gas chromatography calibration. While the principal component is ethane, a saturated acyclic hydrocarbon, the presence of nitrogen as a balance gas may affect classification. Under Chapter 29, only products dissolved in water or specific solvents are covered, so this mixture may not qualify as a pure chemical compound.
