Hello everyone, the following SCG protein purification system company and you talk about the working principle of the UV detector as follows, I hope to help you. The working principle of the ultraviolet detector is based on the law of light absorption. The light emitted from the light source passes through the slit, filter, sample cell to the photoelectric growth tube, so that the change of the light intensity caused by the different sample concentration is converted into the change of the photocurrent. This photocurrent is input to the logarithm through the amplifier The converter converts the transmittance T to the output of A, that is, A = 1g — = εCL where ε is the molar extinction system of the sample to be tested, C is the sample concentration, and the unit is mol / L, and L is the optical path, Use centimeters as the unit. According to the above formula, A is measured and the sample concentration C is known. If the recorder is directly input from the amplifier, the change in the transmittance T of the sample is drawn, and if the input from the logarithmic converter is input to the recorder, the change in the optical density of the sample is drawn.
