1. A system for extracting compounds from botanical material, comprising:
a heater for sequentially vaporizing the botanical material at specified temperature values, each specified temperature value causing a respective vaporization temperature of one or more of the compounds in the botanical material to result in respective vaporized one or more compounds;
a gas inlet for receiving an inert gas, the inert gas being for sequentially aerosolizing each of the respective vaporized one or more compounds into respective aerosolized one or more compounds;
a corona electrode for sequentially charging each of the respective aerosolized one or more compounds;
an electrostatic precipitator including a frame which defines an interior for receiving and sequentially precipitating each of the respective charged aerosolized one or more compounds into respective precipitated one or more compounds, an axis of rotation central to the frame, a motor for controlling rotation of the frame around the 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 sequentially collecting each of the respective precipitated one or more compounds for each specified temperature value that are externally centrifugally expelled from the frame when the frame is rotated.
