Introduction

The procedure to JJF1002-2010 "national verification procedures write rules", JJF1001-2011 "Universal Measurement Terms and definitions "as the basic norms develop. In making this procedure, reference is made to GB/T 29022-2012 size analysis by dynamic light scattering (DLS) (et With the use of ISO 22412.2008) and GB/T 19627-2005 Particle size analysis by photon correlation spectroscopy (identical with ISO 13321.1999) in part. This procedure is the first release. Dynamic light scattering particle size analyzer test procedures

1 Scope

The order applies to dynamic light scattering method to measure liquid insoluble particles having an average particle diameter of a particle size analyzer first seizure Set, and use the subsequent verification check. 2. References GB/T 19627-2005 size analysis photon correlation spectroscopy GB/T 29022-2012 size analysis by dynamic light scattering (DLS) For dated references, only the dated edition applies to this procedure; undated reference documents Member, the latest edition (including any amendments) applies to this procedure.

3 Overview

Dynamic light scattering particle size analyzer (hereinafter referred to as the instrument) measurement principle. When a monochromatic laser irradiation to be Sample to be measured, it will generate a certain intensity of scattered light at a certain angle. Since the liquid molecules suspended particles by random motion Impact and do irregular Brownian motion, so the observed intensity of scattered light will continue over time the ups and downs. Based on Brownian motion Stokes - Einstein equation, when the temperature of the suspension and the viscosity is known, through the analysis of these To evaluate the function of the scattered light intensity over time fluctuation of an average size of the particles (intensity weighted harmonic average particle diameter). The apparatus generally consists of a laser generator, an optical lens, and the sample cell temperature control tank, a photon detector, a signal processing unit, Calculate and display unit and other components, the structure shown in Figure 1.
