Introduction
A laser particle size analyzer is an instrument used to measure the size distribution of particles in a sample, such as powders, suspensions, and emulsions, using the principle of laser diffraction, and it is used in the pharmaceutical, chemical, food, materials, and many other industries for quality control, research, and process monitoring. In operation, the sample is dispersed in a suitable medium, and a laser beam passes through the particles; the particles scatter the light, and the scattering pattern, which depends on the particle size, is detected by an array of detectors, and the size distribution is calculated from the scattering pattern using Mie theory or Fraunhofer diffraction theory; the instrument measures particles over a wide size range, typically from nanometers to millimeters, and it provides a complete size distribution, including the mean size, the D10, D50, and D90 values, and other statistics, and the measurement is fast and can be automated. Laser particle size analyzers are used for measuring the particle size of pharmaceutical powders and formulations, for quality control of powders and granules, for characterizing emulsions and suspensions, for measuring the particle size of cement, pigments, ceramics, and other materials, for monitoring milling and grinding processes, for research and development, and for many other applications, and they are available as benchtop instruments and online analyzers, with features such as wide measurement range, high resolution, and data analysis software. With their wide range and accuracy, laser particle size analyzers are essential for particle characterization.

FAQ
Q1: What testing scenarios is this analyzer mainly applied to?
A: The laser particle size analyzer is used in chemical manufacturing, pharmaceutical development, food processing, mineral processing, materials science, environmental monitoring and research to measure the particle size distribution of powders, suspensions and emulsions using laser diffraction technology for quality control, product development and research. It supports pharmaceutical powder and granule particle size testing, chemical powder characterization, food ingredient particle size analysis (flour, sugar, milk powder), mineral and cement particle size measurement, material science research, environmental particulate analysis, and industrial quality control. The laser diffraction method provides fast, reproducible particle size distribution over a wide range, supporting product development and quality assurance.
Q2: What standards does the analyzer comply with?
A: The laser particle size analyzer follows ISO 13320 for laser diffraction particle size analysis, USP <429>, EP 2.9.31, ASTM B822, and relevant GB/T standards including GB/T 19077. The instrument complies with IEC 61010 laboratory safety standards and IEC 61326 EMC standards. Calibration should use certified particle size standards traceable to international standards (e.g., NIST-traceable polystyrene beads).
Q3: What is the warranty period for the whole machine and key components?
A: The whole laser particle size analyzer is covered by a 12-month warranty. The laser source, detector, optics, sample dispersion system, software and housing are covered, while standards, tubing and fuses are consumables or accessories. Damage from improper use or unauthorized repair is excluded. Extended service contracts are available for this analytical instrument.
Q4: Is this device difficult to operate? Is professional training required?
A: Operation requires trained analysts familiar with particle size analysis, sample dispersion and data interpretation. We provide operation manuals, training and application support. Proper sample preparation (dispersion, concentration), method selection, calibration, optical parameter selection (refractive index) and result interpretation are important for accurate particle size measurement.
Q5: What is the typical lead-time for order delivery?
A: Standard models require 7-30 working days. In-stock units can ship within 3-7 working days. Custom configurations or large built-to-order systems may require additional time, and we confirm the exact schedule before order confirmation.
Q6: Is regular calibration required? What is the recommended calibration cycle?
A: Calibration with certified particle size standards recommended every 6-12 months. Routine verification with a standard before each analytical batch for regulated work. Laser output and detector performance verified periodically. Sample dispersion system checked. Full system performance verification annually. Software updates installed as needed.
Q7: Are supporting consumables universal?
A: Calibration standards, dispersion media, tubing and cleaning supplies are available from laboratory suppliers, though standards should be certified. Long-term consumable cost is low to moderate depending on sample volume.
Q8: Can I customize parameters or supporting accessories?
A: Customization includes measurement range, dispersion type (wet, dry), sample capacity, automation level, detector configuration, software features and accessories. Additional dispersion units and accessories can be ordered separately. Custom orders extend delivery lead-time.
Q9: Does the purchase include on-site installation and commissioning service?
A: Yes, laser particle size analyzers include on-site installation, commissioning, calibration and operator training by certified specialists. Site preparation guidance is provided before delivery.
Q10: What types of samples are compatible with this equipment?
A: The laser particle size analyzer measures particle size of powders, suspensions and emulsions within the particle size range (typically 0.01-3000 micrometers), concentration and dispersion specification. Different sample types require specific dispersion methods (wet for suspensions, dry for powders) and optical parameters (refractive index, absorption). Very fine nanoparticles may require additional techniques (dynamic light scattering). Users should select appropriate dispersion method for the sample, optimize sample concentration (obscuration), use correct refractive index for the material, ensure proper dispersion (sonication, stirring) without breaking particles, calibrate with certified standards, and report results as particle size distribution (D10, D50, D90, span) with method parameters specified. The instrument should be maintained per manufacturer schedule, and the optics should be kept clean. For pharmaceutical use, follow validated methods per USP/EP requirements. The sample should be representative and properly prepared. Dry dispersion should use appropriate pressure to avoid particle breakage. The laser should be allowed proper warm-up time before measurement.
