I am currently working on the suspended photocatalytic water splitting experiment. I do not have a gas chromatography apparatus in my university. So, I have to send my evolved gas sample to another university. So, I have to store my gas samples for a week or two.
Q#1. What can be the best gas sampling bags to use for storage which are not expensive and how can I attach them to my reactor which is only a flask with a suspended catalyst?
Q#2. I will use a gas chromatography apparatus (Model: GC-2010, Manufacturer: Shimadzu). Which analysis should I perform on the sample and which carrier gas can be used?
Hi Saqib Ali ,
Q1 - I think you would need a bubbler set-up and a gas sampling port. You can Google to double-check the set-up to see what apparatus you would need.
Regards Q2, you would need to check what detector and column the GC you plan on using currently houses. Assuming you are only monitoring the H2 production, you should check whether the GC has a PLOT column and a TCD detector. Ar gas can be used as a carrier.
Goodluck!
For gas sample storage,Tedlar bags are a cost-effective option that can be securely attached to your reactor using a gas-tight valve. For analysis with the GC-2010, perform gas chromatography to identify components like hydrogen and use helium or nitrogen as the carrier gas.
