Thermal analysis testing

If you need some Thermal analysis done on juices I can provide it. I have a new Mettler Toledo DSC 822 that will VERY accurately provide you with detailed graphs on melting points of each ingredient in your juices. If you want some sample work just shoot me a message. Thanks!

DSC is not useful on liquids. TGA would be a better choice, but I don't think you'd gather any useful data.

The only analytical anaysis I'm interested in is checking the nicotine content of juices. This would be a simple matter for me using HPLC. However, I don't have any pure nicotine to use as a reference standard. Pure nicotine seems difficult to obtain. I could order it through my company using Fischer Sci, but I have no way of justifying the purchase since the industry I work in doesn't use it.

It seems to be useful. I think it would be good for a juice maker because if someone knows what temperature their atomizer is functioning at, then they can tell what ingredients aren't burning correctly. Ive noticed cheap Dekang juices have one ingredient that doesn't melt until around 350 degrees C. Im guessing its some kind of flavor. Although when i test lets say Halo juice, everything evaporates between 180-250 C. When i put these on a hotplate at 230 C the high dollar stuff completely vaporizes, while dekang has a lot of black residue left (Im guessing this attributes to atomizer failure). I also think that measuring the curvature of the nicotine's melting point you could just about pinpoint the amount of nic thats in your juice. It would be a very close estimate i think.

Hopefully no ingredients are burning.

What temperature does an atty get to anyway? Wouldn't it vary with the voltage on the device and the resistance in the atty? You could be getting anywhere from 3 or 4 watts at the atty, and up to 12 or more depending on your configuration. It seems as though the device is the largest variable in the vaping equation.

It would be nice to know a juice's optimal vaping set-up though . . . juice x vapes best at 8 watts, while juice y vapes best at 5.

lol yea i dont think anythings "burning" i guess i didnt word that right, buuut you know what i mean. Does anyone know those atty temp specs? Id like to know what temp a 510 BogeTech cartomizer runs at 3.7 volts
