We were tasked with designing a flame sampling flow system, a heated catalytic chamber, and a mass spectrometer interface. These three components when used in conjugation will build an experimental facility to enable the analysis of the gas products of flames & thermochemical catalytic reactions with an Atmospheric Pressure Interface - Mass Spectrometer (API-MS). There are two modes of operation for this flow system. In mode one flow reacts in the catalytic test chamber then into the API-MS for data collection. The flows temperature is controlled by a PID program. Flow will reach temperatures of up to 823K, and its pressure will allow for manual adjusting. In mode 2 the flow is sent through a flame sampling system where mixing of the flow and flame will occur. After mixing the gaseous products are sampled with the API-MS. The goal of the project is to build a system that can analyze the gaseous products sampled with a dilution probe from a burner-stabilized premixed flame or of a catalytic reaction.
