The measured particle size of the optical equivalent, which is equivalent to the measurement system, the response to the same standard particle size. This definition requires the use of a known standard particle size particle size analyzer calibration. This section applies to a diameter of from about 0. 05 microns to a few millimeters particles. About 0. 05��m ~ 20��m wide airborne particles mainly by light scattering method. Larger particles measured by the light sensor abatement. For liquid containing particles scales at 0. 05 micron to several microns particles by light scattering method. 1 micron to millimeter size range of particles by a light reduction method. Any instrument that can be measured by particle size range is usually close 100: 1, when more than the minimum particle dimension of the fine particles is about 100 times better resolution of measurement, the result is greater than or equal to the maximum size instrument channel threshold scale. This section considers a particle size analyzer in the light-sensitive region as caused by the presence of individual particles flux response to changes in the collection. For this reason, those who rely on the interaction of light and particles generated by the data indicating only the degree of particle movement unit is not discussed in this section.

In the optical design of these instruments, a light source Types and respect the way the interaction of light particles and the like are different. For the above reasons, almost the same for different instruments derived microparticles The measured data is often different. In addition, the degree of interaction between individual particles and light, in addition to the impact of particles by size, but also by a variety of physical Effect parameters. This section is intended to define the interaction of light with the measurement data generated on the basis of size and reduce its variability. Usually single particle light interaction with the instrument for particle size measurement, or relates to the measurement of light scattering caused by a single particle, or involved And to present in the measurement light beam reduction of particulate-induced. This section will discuss the particles interact with light phenomenon being measured in the raw Li, general performance and operating parameters and equipment as well as equipment and manipulate the flow of particles related to the environment as a specification. Model specific instrument operation For performance and not within the scope of this section. The method of single grain size distribution and the interaction of light measurement Part 1. Single particle light interaction1 ScopeGB/T 26647 in this section to the particle size measurement selection and operation of the device to provide guidance, such a device by measuring the gas phase or liquid Phase interacting with the phenomenon of individual particles to determine the size and number of particles. The measured particle size of the optical equivalent size, which is equivalent to the measured Make the same size when the amount of particles in response to a standard system. This definition requires the use of a known size standard particle size analyzer calibration. This section applies to a diameter of from about 0.05 microns to a few millimeters particles. About 0.05μm ~ airborne particles within the range of 20μm Mainly determined by light scattering method. Larger particles measured by the light sensor abatement. For liquid carrier particles at the scale of a few microns to 0.05 microns Particles in the range of measurement by the light scattering method. 1 micron to millimeter scales particles by the light reduction assay. Any particle size analyzer can measure Given scales usually close 100.1, with better resolution when measuring about 100 times greater than the smallest particle dimension particles obtained Result is greater than or equal to the threshold value of the largest dimension scale instrument channel. This section considers the change in particle size analyzer to collect the luminous flux of light-sensitive area due to the presence of individual particles caused by the response. by For this reason, those who rely on the data produced by the interaction of the particles with light, only indicates the extent of the movement of particles instruments are not discussed in this section. Note. For those instruments depends mainly on aerodynamics scale particles to produce data, including aerodynamic particle size analyzer, or phase Doppler particle size analyzer Etc., not discussed in this section. These instruments are not measured particle size depending on the degree of light and particle interactions, but with a correlation method to measure hydrodynamic Given particle size, the particle motion in the predetermined distance or the time required for the particle velocity is defined.2 Normative referencesThe following documents contain provisions which, through reference GB/T 26647 in this section constitute provisions of this section.
