1. A system for botanical material, comprising:
a gas inlet for receiving an inert gas, the inert gas being for aerosolizing respective vaporized one or more compounds of the botanical material into respective aerosolized one or more compounds;
a corona electrode for charging the respective aerosolized one or more compounds;
an electrostatic precipitator including a frame which defines an interior for receiving and precipitating the respective charged aerosolized one or more compounds into respective precipitated one or more compounds, and a motor for controlling rotation of the frame around an axis of rotation to perform said precipitating; and
a collection system at least part of which is positioned radially exterior from the frame with respect to the axis of rotation, the collection system for collecting the respective precipitated one or more compounds that are externally centrifugally expelled from the frame when the frame is rotated.
