EQ2000 teaching experiment spectrometer experimental spectrum measurement diagram:
Application of fluorescence detection of liquid in cuvette holder:
The cuvette holder in the figure below, the left fiber is connected to the light source (HL2000 halogen light source or DH2000 deuterium halogen light source can be selected), the right fiber is the transmission and absorption measurement end (MAX2000 fiber spectrometer or EQ4000 fiber spectrometer can also be selected ), the front side fiber is the fluorescence/excitation light measurement end (MAX2000 fiber spectrometer or EQ4000 fiber spectrometer can also be selected).
This measuring system is a spectrum measuring system designed for a cuvette with a light path of 1cm, which can measure:
1. The transmittance and reflectance of the liquid sample in the cuvette.
2. Absorption and fluorescence spectra of the liquid sample in the cuvette.
