Introduction

This type of evaluation outline evaluation projects. Wavelength indication error, wavelength reproducibility, detection limit, measuring line , Fluorescence spectral peak intensity repetitive fluorescence intensity upper limit value shown in 10min drift and other technical indicators adopted JJG537-2006 "fluorescence spectrophotometer" metrics; within 10min zero line drift index using Industry Standard JB/T 5594-1991 "fluorescence spectrophotometer" in the index; increase the signal to noise ratio in the measurement of performance requirements, because Indicators for the different requirements of different manufacturers, which indicators to manufacturers declaration or instrument specification is based on indicators; in the pass Technical requirements increased dielectric strength, the power supply voltage and environmental adaptability of the pilot project, dielectric strength, power supply Pressure adaptation index using Industry Standard JB/T 5594-1991 "fluorescence spectrophotometer" in the index; Environmental Testing Mainly related to low temperature test, high temperature test, low temperature storage test, high temperature storage test, alternating hot and humid test, crash test Test, drop test and other projects, technical requirements and testing methods GB/T 11606-2007 "Environmental analysis instrument test Test method "in the relevant content.

3 Overview

Fluorescence spectrophotometer (hereinafter referred to as the instrument) from the light source system, excitation monochromator system, sample room, single launch Color system, the detector system and a data processing system structure. The light emitted by the light source, through the excitation monochromator becomes After the monochromatic light, according to the fluorescent substance on the test sample cell, thereby excite fluorescence emission monochromator is collected by Monochromator dispersion into monochromatic light, and fluorescence intensity was measured into an electrical signal by a detector system, the data processing system And converted into digital spectrum. For a given material, the intensity of the excitation light and the wavelength is fixed, the fixed thickness of the liquid layer, the concentration of the solution At lower concentrations the fluorescence intensity F c and the fluorescent substance, the instrument constant k have the following relationship. F = kc According to this principle, a fluorescence spectrophotometer can be applied to the determination of the nature and amount of the fluorescent substance. The instrument can be divided into two categories monochromator. A class is a dispersive monochromator, a class B filter monochromator.
