Hello everyone, the protein purification system manufacturers have compiled the following content about the UV detector for you, let's understand it together. The basis of the working principle of the ultraviolet detector is the law of light absorption. From the light announced by the light source through the slit, filter, sample cell to the photoelectric growth tube, the beam intensity change caused by the different sample concentration is converted into a change in photocurrent. The converter converts the light transmittance T into A output, 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 mole / liter unit is selected, 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.
UV detector control system: 1. The UV detector control system has a black aluminum connection temperature sensor, and the UV detector control uses the blackboard heating temperature, the temperature is more stable. 2. The radiometer probe is fixed instead of loading and unloading each time. 3. High precision of radiation measurement, display and special ultraviolet radiation measurement instrument. 4. The radiation does not exceed 50 watts per square meter. 5. Illumination and condensation of the UV detector can be independently controlled to replace the cycle control. 6. The independent control and replacement cycle time and control time of the condensation light of the ultraviolet detector can be arbitrarily set at 1000 hours
The ultraviolet detector is the detection equipment in the liquid chromatography. The instrument is equipped with a chromatography column, a constant flow pump, and a part of the collector. It constitutes a complete set of liquid chromatography separation analysis system. It can be applied to modern biological research, drug determination, agricultural scientific research, chemical industry, food and medical units to quantitatively analyze samples with ultraviolet absorption.
