Abstract: In-situ optical spectroscopic monitoring, characterization and feedback control of extraction and purification processes of compounds such as oils, alkaloids, flavonoids, terpenes and cannabinoids derived from plant material are described. Liquids from an extraction or purification process flow down an optically transparent tube, such as one made of glass. An in-situ optical monitoring assembly is configured to be mounted onto the tube to measure optical properties of the liquid extract or liquid condensate as it flows in the tube. Optical properties of the flowing liquid may include optical transmittance, reflectance, photoluminescence, scattering, absorbance, turbidity, nephelometry, polarimetry and colorimetry. The output of the optical monitoring assembly can be used to display spectral and other about the flowing liquid, set alarms to notify an operator of a predetermined condition such as a set point, and used to control extraction or purification process.

Abstract: A portable vacuum pressure graphing gauge device enabling users of vacuum systems the ability to see trends of vacuum systems through real time plotting of a pressure vs. time curve on a hand held instrument, enabling them to understand what is going on in their system, or the like. A device may include several graphical modes designed to even more easily interpret vacuum data, and packaging that is rugged and versatile including a magnet, kickstand, wireless connectivity, visual and audible set points, automatic sensor fault detection, and several vacuum pressure measurement units to choose from, or the like.
