Resumen
Describes a method based on the separation of carbon monoxide, methane and corbon dioxide by gas chromatography through a Carbosieve B or Porapak N column, followed by passage through a column of hydrogenation catalyst which transforms the oxides of carbon to methane thus allowing the use of a flame ionization detector to make the final determination.
