Detailed information on AquaTracka deep-sea fluorescence meter

Deep-sea fluorescence meter

The multifunctionality of AquaTracka III fluorometer is achieved by selecting appropriate optical narrowband filters to match the excitation and emission bands of fluorescent substances, such as chlorophyll-a, rhodamine, and luciferin, and using the same excitation and emission bandpass filters can be configured as a turbidity meter.

The light emitted by the xenon arc lamp is cut into intermittent light by a collimator, and the excitation light monochromator is converted into monochromatic light. This light is the excitation light of the fluorescent substance. The fluorescence emitted by the measured fluorescent substance under the excitation light is converted into monochromatic fluorescence by the monochromator and then irradiated onto the photomultiplier tube used for measuring the sample. The photocurrent generated by it is amplified by an amplifier and output to the recorder. The gratings of the excitation light monochromator and the fluorescence monochromator are controlled by a cam driven by an electric motor. When measuring the fluorescence emission spectrum, the grating of the excitation light monochromator is fixed at the appropriate excitation light wavelength, and the cam of the fluorescence monochromator is rotated to adjust the fluorescence intensity of each wavelength. The signal is output to the recorder, and the recorded spectrum is the emission spectrum, also known as the fluorescence spectrum.

When measuring fluorescence excitation spectra, fix the grating of the fluorescence monochromator at the appropriate fluorescence wavelength, only allow the cam of the excitation light monochromatic port to rotate, and output the intensity signals of each wavelength of excitation light to the recorder. The recorded spectrum is the emission spectrum. When conducting quantitative analysis of sample solutions, fix the excitation monochromator at the selected excitation wavelength and adjust the fluorescence monochromator to the selected fluorescence wavelength. The signal obtained by the recorder is the fluorescence intensity of the sample solution.
