Trace CO and CO2 In Hydrogen and Light Gaseous GC Gas Chromatagraph
UOP603
1.Principle
Trace CO and CO2 in the gas sample is injected into the packed
column of GC,and methane is generated by the converter. The FID is
used to detect the methane product, and the CO and CO2
contents are quantified by the external standard method.
2.Analysis instruments
2.1 Column A:9.1m1/16 inch OD,0.050 inch ID stainless steel pipe
filled 80-100 mesh “TDX-01
2.2 Column B: 3m1/16 inch OD,0.050 inch ID stainless steel pipe
filled 60-80 mesh 13X Molecular sieve；
2.3 Gas Chromatagraph: constant temperature,FID detector；
2.4 Gas converter
3 Operation steps
Repeat to inject standard gas sample to obtain the peak area, and
calculate the correction factor of each component with the standard
gas content;Re-inject the sample and calculate the sample content
from the peak area of each component of the sample.
R=A/B
In the formula: A---Content of each component；
R---Correction factor of each component；
B---Average peak area of each component,
4 Calculation
Use below formula to calculate content of each component:
Content of each component: mass-ppm=E·R
In the formula: E=peak area of each component；
R=Correction factor of each component；
