A compound algae culture apparatus is provided, which includes a photobioreactor module, a growth regulating module, a circulation transfer module, and a circulation pipeline module. The photobioreactor module includes at least one photobioreactor unit, and the growth regulating module includes at least one growth tank unit. The photobioreactor unit includes a light-transmitting coiled pipe. The growth tank unit has a tank body, and a plurality of partitions are disposed in the tank body to divide an inside of the tank body for formation of a curved flow channel A culture fluid for culturing algae passes through the photobioreactor unit and enters the growth tank unit. A volume of the growth tank unit is larger than a volume of the photobioreactor unit, and a residence time of the culture fluid in the growth tank unit is greater than a residence time of the culture fluid in the photobioreactor unit.

A transfer device includes at least one pump unit provided for a defined gas transfer between a first, closed-off space of an installation, in particular a photobioreactor installation, and a second space which is separate from the first space. The at least one pump unit is embodied as a selective oxygen pump.

A system adapted for growing and harvesting algae and for obtaining products thereof adapted for domestic use, comprises a Photo-bioreactor adapted for use in a home environment, said Photo-bioreactor being controlled by a CPU control unit, said Photo-bioreactor being coupled to a Separation Harvesting and Extraction Unit (SEU), adapted to receive algae from said Photo-bioreactor as an input, and to generate therefrom an algal paste, said SEU being in turn coupled to an extraction unit adapted to receive said paste and to extract a desired material therefrom, said system being controlled and monitored by a CPU control unit.

Apparatuses and methods for microscopic analysis of a sample by simultaneously characterizing infrared absorption characteristics of a plurality of spatially resolved locations are described herein. These apparatuses and methods improve sampling times while collecting microscopic data regarding composition of a sample across a wide field.
