核酸蛋白检测仪系液相色谱中的一种紫外检测装置,通常用来测量柱层析洗脱液中所含有核酸和蛋白的含量及样品浓度变化,并由记录器将待测样品的光吸收透射比描记下来。检测仪由电子线路部分、光学系统和记录器组成。光学系统是仪器的核心,而光学系统的单色性能则是影响测量结果准确性的主要因素。为提高单色性能,仪器除选用发光器件的波长与待测试样的吸收波长较接近的光源外(如核酸对紫外光的吸收峰在254nm,选用工作波长在2537×10~(-10)m的汞灯作
Nucleic acid protein detector in liquid chromatography in a UV detection device, usually used to measure the column eluate contained in the nucleic acid and protein content and sample concentration changes, and the recorder will be tested sample light absorption Transmittance profile down. Detector by the electronic circuit part, optical system and recorder. The optical system is the core of the instrument, while the monochromatic performance of the optical system is a major factor affecting the accuracy of the measurement results. In order to improve the monochromatic performance, besides the light source with the wavelength of the light-emitting device selected and the absorption wavelength of the sample to be tested (for example, the absorption peak of the ultraviolet to the nucleic acid is 254 nm, the working wavelength is 2537 × 10 -10 m mercury lamp for
