Here is some data that demonstrates that the fraction finder does not see cannabinoids but rather sees residual pigment.
First image is a control of 0g cbd isolate in 20mL ethanol.
Second image is .2g CBD isolate in 20mL ethanol, or 10x the concentration @arometrix claims to detect.
Third image is 2g CBD isolate in 20mL ethanol. You can see a distinct double peak shape within the hump.
Fourth image is .1g CBD distillate in 20mL ethanol. The fluorescent light is clearly coming from a non cannabinoid source.
@spdking here’s the white paper^
When small amounts of pigmented oil are used the fluorescent response is huge. When large amounts of cannabinoids are used the pigment fluorescence is eventually visible.
Clearly the sensor doesn’t work as advertised.
However it does work great as a Pigment Tracker
