I have a gas-phase reactor system that uses the FID of a 7980A to analyze the product mixture. Currently, I have a pressure buildup (up to 30 psi - the carrier gas delivery pressure) when the system is stationary. When the gas sampling valve actuates to take a sample, the pressure buildup is relieved over the course of the injection. Based on these observations:
1) Where is the clog in my system?
2) What steps can I take to resolve this?
Thanks in advance for any suggestions.
