In particular, the present disclosure relates to the operation of a flame ionization detector for carbon dioxide based chromatography, such as supercritical fluid chromatography. The present disclosure includes a method of matching a chromatographic column with a flame ionization detector inner burner including providing a chromatographic column with an internal diameter, determining an optimal mobile phase flow rate for the chromatographic column, calculating an optimal inner diameter of the inner burner that combined with the internal diameter and flow rate of the column produces optimal detector performance, and providing a flame ionization detector inner burner having an inner diameter substantially equal to the calculated optimal inner diameter."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Flame ionization detection for supercritical fluid chromatography employing a matched separation column and flame burner","description":"The present disclosure relates to flame based detection methods for compressed mobile phase chromatography.
