用气相色谱来测CO和CO2的方法

The Gasohol Analyzer Channel is an analytical tool principally developed for the
determination of oxygenated additives (alcohol's and ethers with a maximum boiling
point of 100°C, in various gasoline's and related products.
The sample is injected by means of a syringe (optional automatic liquid sampler) onto
a series of capillary columns. From a short CP-Sil 5 CB column, the first fraction,
containing the components of interest is sent to a second, long TCEP column; the rest
of the sample is backflushed.
By varying the backflush time and the temperature program, also aromatics may be
determined. Methods may be developed to perform the determination of benzene,
BTX or aromatic profiling.
The Gasohol Analyzer Channel is set for the determination of the mentioned
components at percentage levels.
