Chapter 1. Overview is characterized by wide SP-UV1000/SP-V1000 visible spectrophotometer wavelength range, high sensitivity, powerful functions, ease of use, simple structure and acceptable appearance, especially the application of large-screen LCD, high-

precision A/D converter and nonvolatile memory, which makes the instrument uniquely advantageous among the products of the same grade and widely applicable textile, chemical, pharmaceutical, biochemical, metallurgical, materials, environmental protection, medical assay and education industries, as one of the important quality control instruments in the analytical testing industries and an essential instrument in conventional labs. industry, light I. Instrument rationale and structure The rationale of spectrophotometric analysis involves using the selective absorption of light of different wavelengths by samples to perform qualitative and quantitative analysis of the samples and judging the structure and chemical composition of substances through analysis of absorption spectrum. This instrument works on the principle of relative measurement, i.e., selecting a certain solvent (distilled water, air or test sample) as the reference solution and setting its transmittance (i.e., transmission rate T) as 100%, while the transmittance of the testing sample is derived with reference solution as reference standard. The changes in transmittance (transmission rate T) will have a certain functional relation with the concentration of the test sample and it complies with the Lambert-Beer's Law within a certain range. T=I/Io A=KCL=-log I/Io Wherein T transmittance (transmission rate) C solution concentration K absorption coefficient of solution L length of liquid layer in light path 2 DLAB Scientific Co., Ltd. YuAn Road 31, Airport Economic Core Zone,Shunyi District,Beijing101318,P.R.China I intensity of light irradiated on the photoelectric converter through tested sample Io intensity of light irradiated on the photoelectric converter through reference test sample. SP-UV1000/SP-V1000 ultraviolet/visible spectrophotometer is a domestically leading new-generation UV-VIS spectrophotometer. These are developed based on this rationale, in conjunction with the modern precision optics, the latest microelectronics and other high-end new technologies. II.
