Interior of the Andromeda chamber before closing for this experiment and recording this spectrum (SPECTRUM_DM_20131017_100). The cylinder at the top of the image is the condenser. The tholin sample is lightened by the laser beam of the fiber optics. The location of the thermocouple located at the valve level is indicated by a small numbered piece of paper.
