Method of
work:

Spectrophotometer analyses electromagnetic spectrum. Spectrophotometer is composed of radiation source, monochromator and detector. Monochromator is calibrated in way that is possible to change wavelenght of radiation that pass through. The spectrum is evolved by recording intensity of the radiation which sample has absorbed, missed or reflected depending on wavelenght.

Department,
room, location:

Department for Textile Chemistry and Ecology, PhD Research Cabinet, Savska cesta 16/9
