@alexsiegel also has an inline THCa and pigment detector

The THCa Tracker has been working like a charm! Hardware is ready to go follow me on instagram @alexsiegel94 to check out updates.
We have been using it to view extraction saturation point in order to use ideal amounts of solvent. Never over or under extracting again.

In addition to the 190–850 nm UV–VIS absorption spectroscopy sensor suite we developed for extraction, Raman spectroscopy is also commonly used in this domain. We maintain multiple sensors in-house for R&D, alongside several additional sensors typically deployed in the oil and fuel industries.
Across processing, these systems monitor flow rate, temperature, capacitance, density, and spectral response, along with a wide range of secondary indicators during oil production. Post-production testing is equally critical for bio-oils, as there are numerous potential contamination pathways that must be identified and controlled. At the extraction stage, our sensor stack is focused on quality rather than quantity, but also solvent saturation.
With absorption spectroscopy, once the baseline is zeroed using the solvent as a reference, even very small compositional changes can produce disproportionately large spectral shifts. While all molecules absorb light to some degree, only certain species exhibit fluorescence. Under these conditions, detecting terpenes—or other molecular constituents—becomes straightforward and highly sensitive.
Using our distillation-phase spectroscopy sensor, we were able to track terpene fractions, heads, body, and tails in real time, identifying fraction transitions with second-level precision. Based on prior operational data, THC and CBD also exhibited distinct absorbance signatures during distillation, despite appearing visually identical. This spectral differentiation enabled real-time compositional awareness that would be impossible through visual observation alone.

What does it cost? Is it measuring cannabinoids in real-time?
Thanks @cyclopath 100% inline sensor are just another tool to lock in quality and consistency.
they do, they have a full suite.
where can I find more info on this? What extraction types can this work for.
Isn’t Raman crazy expensive?
I’d be happy to send a quote. Reaching out to you over DM.
Yes! The THCa Tracker directly measures THCa in solution quantitatively and displays it on a time-based readout. You can see THCa increase and decrease in your solvent in real time.
This week I am flying to a lab in Oregon to get some media footage taken. I will be putting out a white paper soon
