Greetings from UCONN!
We have an Agilent 7890B GC system coupled with an Agilent 5977B MSD.
We previously used it to online monitor the composition of the simulated exhausted gas, which mainly contains CO, CO2, H2, O2, NO, C2H4, C3H6, C3H8, and the method was developed for these components.
The basic setups and system schematics are shown in the attached images.
Now we want to use this system to monitor the products of CO2 hydrogenation reactions, which mainly contains CO, CO2, CH3OH, dimethyl ether (DME) and CH4.
Among them, CH3OH, DME, and CH4 can be in quite low concentration, ~100ppm.
I want to know if the current setups, especially the columns, can be used to measure the concentration of CO, CH3OH, DME, and CH4.
If it works, any suggestions are welcome.
I moved this post to an application area for better visibility .
