Introduction

This type evaluation outline based on JJF 1016 "Guidelines for the preparation of evaluation criteria for measuring instruments", JJF 1015 "meter Gage Type Evaluation and Type Approval General Specification "and JJF 1001" General Measurement Terms and Definitions ". The technical indicators of this type evaluation outline reference JJG178-2007 "UV, visible, near-infrared spectrophotometry Meter "and GB/T 11606-2007" analytical instruments environmental test methods "and other technical regulations. This type of evaluation outline for the first time released. UV-visible spectrophotometer type evaluation outline

1 Scope

This type of evaluation program for the wavelength range of 190nm ~ 1000nm, continuously adjustable wavelength of the spectrophotometer New product type evaluation work.

2 reference documents

This specification cites the following documents. JJG178-2007 "UV, visible, near-infrared spectrophotometer" JJF 1001-2011 "Common measurement terms and definitions" GB 4793.1-2007 "Safety requirements for electrical equipment for measurement, control and laboratory use" GB/T 11606-2007 "analytical instruments environmental test methods" For dated references, only the dated version applies to this specification; for undated references The latest version (including all amendments) applies to this specification.

3 Terms

3.1 spectrophotometer spectrophotometer Based on Lambert-Beer's law, the theory used for colorimetric analysis. 3.2 UV-visible spectrophotometer ultraviolet-visiblespectrophotometer The wavelength range of 190nm ~ 1000nm, wavelength continuously adjustable spectrophotometer.

4 Overview

UV - Vis spectrophotometer (hereinafter referred to as the instrument) is based on the material of UV - visible light radiation of choice Absorption and Lambert-Beer Laws Quantitative analysis of substances and qualitative identification of the instrument. The mathematical expression of Lambert-Beer's law is. A = -lg (I/Io) = - lgT = klc The physical meaning is that when a bundle of parallel monochromatic light perpendicular to the measured substance solution, the solution absorbance A And the concentration of light-absorbing material c and liquid layer thickness l is proportional to. The instrument is mainly composed of light source, monochromator, sample chamber, detector, signal processing and display and storage system.

5 legal management requirements

5.1 unit of measurement UV - visible spectrophotometer using legal units of measurement. 5.2 accuracy (maximum allowable error) requirements The accuracy of the instrument shall be in accordance with JJG178-2007 "UV, VIS, NIR Spectrophotometer" Provisions.
