Comprehensive research and development of biochemical instruments for many years, independent research and development of "ZHD-D dual-wavelength nucleic acid protein detector", for Chinese scientists in the field of biochemical analysis, food research, environmental science, toxicology research, new drug development and other fields of nucleic acid Protein detection, purification and extraction provide a unique analytical tool. The nucleic acid protein detector provides wavelengths of 214 nm, 254 nm, and 280 nm. Built-in computer collector, can be directly connected to the computer to achieve drawing, save data analysis and calculation.
Preparation of nucleic acid protein detectors:
1. Connect the required supporting instruments (detector, collector, constant current pump, recorder) as required.
2. Press the detector power switch and the instrument is warmed up for 20 minutes.
3. Set the recording speed of the recorder to 12cm/h (according to your own requirements) and measure the 10mV file.
4. The flow rate of the constant flow pump is 1-3 ml/min depending on the size of the column.
5. The detector "sensitivity" is adjusted with the "I" file according to the absorbance spectrum, ie the peak size.
6. The detector wavelength was selected to be 280 nm (nucleic acid 254 nm).
