ROFLMAO… Elliot would say just about anything to sell a unit. We’ve had people come through our shop a couple years later and tell the stories about all the crazy things he would say and what he would say about our unit. Which obviously he was lying about his and ours so that way he would sell his.
If you browse through their source code you’ll find that it’s actually just a copy of some old Accustrata code remapped over as a new device. It was probably only a couple hours of work to make the transition because accustrata makes spectrometers.
This sensor was a rushed to market system by elliot.
I have measured the UV source LED and it’s a strong 365nm peak but also with a ton of visible light with most intensity around blue. Without a uv bandpass filter to clean up the signal, it is naturally contaminated with visible light.
You can see the blue light in the emission of the source light in just about every video of its operation and if you have one in hand it’s pretty obvious.
Just noticed we have their fraction finder. Bought the spd setup from lab society. Coworker had issues from the getgo trying to figure it out. Pretty much stopped using it and based his decisions on color. Hittin mid 70s with ff and ended up 92% without it. $25k for the system and they were talking up the FF like its the next big thing.
I had basically the same experience… potency with the ff test batches were barely better than the crude we made it from, when we consistently hit 95%+ going by eye.
No was bought prior to me being hired so about 3 years ago. They were on the fence about the FF too. Didn’t seem worth the extra cost but ultimately decided on it.
In your note above you reference a fluorescence emission spectra obtained from CBDA excited with 365 nm.(figure 5d)
If you note the dual nature of the emission peak. The latter hump is probably the Anion specific contribution over lapping with the Acid’ emission. In salicylic acid studies there are assays based on this latter emission which are used to quantify the concentration of Anion form in any one mixture. Cannabinoid homologues should exhibit similar characteristics.
