分光光度计是一种吸收光谱仪器,它能测定物质在可见及紫外或者红外区域的吸收光谱,是医院药房、临床检验科或中心实验室必不可少的检测仪器,用它来测量某一药物、试剂或样品标本的含量组分,具有精度高,方法快速可靠,可测元素多,测定范围广等特点,尤其是在有机化合物的检测方面应用更加广泛。 早期生产的72型分光光度计,机器结构采用积木式、不仅体积大,而且用光电池作接收元件,灵敏度低,另外,其波长范围仅限于可见光区域,波长范围较窄,而WFZ—800D_2型分光光度计的分析可扩展到紫外、可见光区,因为许多无色的物质在紫外区能出现吸收,所以就能对它进行测定,这样就大大增加了物质测定的范围。
Spectrophotometer is an absorption spectrometer, it can measure the absorption of the material in the visible and ultraviolet or infrared region of the spectrum, the hospital pharmacy, clinical laboratory or central laboratory essential testing equipment, used to measure a drug , Reagents or samples of the content of components, with high precision, fast and reliable method, measurable elements and a wide range of measurement and other characteristics, especially in the detection of organic compounds more widely used. Early production of spectrophotometer type 72, the machine structure using building blocks, not only bulky, and the use of photovoltaic cells as the receiving element, low sensitivity, the other, the wavelength range is limited to the visible region, the wavelength range is narrow, and WFZ-800D_2-type spectroscopy Photometric analysis extends to the UV and visible regions, since many colorless substances absorb in the UV region so they can be measured, greatly increasing the range of material determinations.
