For us on a budget we simply used the exhaust colour to determine if we were getting complete decomposition. For a monoprop, if it's clear it almost a certainty that it's fully catalized. Any thing else means something is amiss.

I can demonstrate this from a video of a peroxide powered motor bike. https://youtu.be/tDLrWbvRyyI This is a wet start, quite typical, to a good clean run

This may sound stupid but once upon a time I was a chemist at Radian Corp. We went to California to do EPA work sampling steam coming from the oil wells (they inject steam to get the thick oil to flow) Anyway we used big fin/fan condensers to cool the steam and used gas chromatography to check for hydrocarbons in the condensate. condensing the exhaust might be a useful way to get the data I'm after. I'm not coming into this to play I need empirical data. Not ballpark results. This is likely too far but it should give you a sense of how serious I am about getting the proper data. > -------- Original Message -------- > Subject: [AR] Re: Peroxide sensor > From: "Henrik Schultz" <henrik@xxxxxx> > Date: Fri, December 18, 2015 12:14 pm > To: arocket@xxxxxxxxxxxxx > > > Just measure the temperature using a thermocouple.
