Without calling the guys frauds or being as naive to say this technology "can't" exist, I'll reiterate.
I think this is an AWESOME concept! Although I don't believe it's as easy as they make it seem with that video.
Before I invest, I want to see how the unit and sensors work. Basically all detectors work in the manner they show. You ionize your sample in some way or another, burning, dissolution and then those ions create a current that you read. I'm not sold...
Chromatography is more complex though and this is how you get your separations. This is the part I have a hard time wrapping my head around, how do they achieve their specificity? Especially with hundreds if not thousands of chemicals in there. Not to mention using vapor vs liquid chromatography for these type molecules.
I could see them having this little portable oven that could be used qualitatively to tell you yes or no, thc is in this cookie. Or yes, your beer contains roofies. Maybe I'm behind the times in analytical instrumentation, but honestly this type device would revolutionize the world.
Maybe their shit is so badass they can't reveal details like that because the government would come after them. Big Pharma putting the hit out on the canna industry and its revolutionaries.
Seriously though, I wish them the best of luck and will definitely keep an eye on this. Hopefully they provide more details. By the way I'm a huge fan of crowdsourcing and gladly donate when I see something I like.
Peace
