Yep, the same radiation as visible light, just longer wavelengths.

I hadn't thought of using the resistance of the liquid, it would be interesting to see how many differents kinds of compounds could be read that way. I wanted to use a probe that will shine infrared radiation through a very small area of the vapor as it passed between the emitter and an IR sensor. The sensor would measure how much of the radiation was absorbed and at what wavelength. A program would display percentages by volume or mass of all the components in the vapor. It's been an interesting thing to research so far, and I think it may have potential.

I was thinking an NPT fitting would be the way to go also. I have something that would work, it's just that the ability to quickly measure all of the compounds I'd like is most likely going fairly expensive, probably about $10- 15,000. I'd like a much cheaper one, we'll see where it goes. Thanks for the input, guys.

Similar to, but I was thinking about a way to use a infrared spectroscopy system that can easily be used in-line on a still. I have a few ideas, but wanted to use a few different sources to get a better idea if it is worth sourcing parts to make a prototype.

Hello everyone, I've never posted before but have learned a lot from this site. I hope this is the right place to ask. I have an idea for a new product and wanted to get some professional's opinions on it before I decide whether or not to pursue production or a patent. The device would measure the components of the vapor as it passes through before the condenser and display it digitally as percentage of water, ethanol, higher alcohols, esters, etc. It could be added in line to existing stills or be put into new stills as an additional option. I feel like it could be a valuable thing to be able to see instantaneous changes in the vapor caused by adjusting the heat input, dephlegmator, or possibly dozens of other variables. It might also make cuts more precise, or maybe make for a more consistent product. How do you all feel about it? Would you buy something that showed exact composition of the vapor at that instant? Would you like to see still manufacturers offer it as an option? How much money would the option be worth? I appreciate any time and thought put into any responses.
