3 Principles of the method
Gas chromatograph is used to analyze and determine oxygen-containing compounds in methanol to olefins water. The water sample to be analyzed is vaporized and split by the chromatograph.
Then, the carrier gas is carried into the chromatographic column, and the oxygen-containing compounds in the water sample to be analyzed are separated through the chromatographic column, and the signal is detected by a hydrogen flame ionization detector.
For detection, the components to be tested in methanol-to-olefins water were qualitatively analyzed according to the retention time of the chromatographic peak, and the external standard method was used for quantification.
