I.Introduction
930N is a variable wavelength adjustment fluorescence spectrophotometer with an excitation wavelength standard configuration for 365nm, emission wavelength range 360-650nm, spectral bandwidth of 12nm, 4-digit LED data display, 4 keys to complete fluorescence values, extensions, concentration factor setting and concentration operations, with RS232 communication port, and equipped with a selected general data processing software package for online operation, more convenient for your further calculations and process on the data , saving time. Also can be use for external serial printer to perform data printout ,convenient for data preservation.
The instrument is widely used in biochemistry, medicine, food, environmental, chemical and other departments for quantitative and qualitative analysis, it is the best choice for school laboratory, factory testing .
