introduction
Many areas require monitoring of particulate pollution, such as. electronic industry, pharmaceutical industry, precision instrument manufacturing, and medical fields. Particles count
The number of particles in the liquid is monitoring contaminants effective equipment. Currently, the law resist liquid particle counter particle size and particle size calibration setpoint
Authentication method, particle size resolution calibration general have three methods, in addition to the body of the method 1, the present section in Annex C, Appendix D
It lists the other two methods. This section is intended to provide a particle counter calibration procedures and test methods to reduce the measurement error of the same instrument
Difference and the difference between different instruments to measure results.
Single particle size analysis of optical measurement methods
Part 3. Liquid Particle Counter resist method
1 Scope
This section GB/T 29024 specifies the method photoresist liquid particle counter (LELPC) calibration and verification methods, the instrument used to measure
The amount of particles suspended in a liquid particle size and particle number concentration. Resist method described in this section based on the measurement of single particles, measured by the method
Given the typical size range is 1μm ~ 100μm.
The instrument can be used to evaluate drugs (such as. injection, water for injection, intravenous injection) cleanliness, can also be used to measure various liquids
The number of particle concentration and particle size distribution.
This section includes the following aspects.
--- Particle size calibration;
--- Verify particle size setpoint;
--- Counting accuracy;
--- Particle size resolution;
--- The maximum particle number concentration;
--- Sample flow;
--- Sampling time;
--- Sample volume;
--- Calibration cycle;
---testing report.
