Guide and selection support
Particle analyzers are primarily used to analyze particle size, shape, and additional properties such as charge and color. Typical application areas include the chemical and pharmaceutical industries as well as materials testing.
When selecting a particle analyzer, factors such as the measurement principle, size range, sample preparation, and analytical precision are crucial. Compatibility with necessary dispersing units is also important.
LabFinder assists in navigation and comparability between different devices to provide users with tailored procurement solutions and to simplify the search for suitable particle measurement systems.
Applications and Benefits
Particle analyzers serve for quantitative and qualitative analysis of particles regarding size, shape, color, and other characteristics. They are essential tools in research and quality control, especially within chemical and pharmaceutical industries, as well as in material testing. Their use ranges from raw material characterization and process monitoring to product release.
Selection Criteria
Key aspects to consider include the appropriate measurement principle for the particle size range, requirements for particle shape analysis, sample type and quantity, and the integration of any dispersing units for sample preparation. Additional factors are ease of operation, measurement accuracy, and compatibility with existing laboratory processes.
Variants and Measurement Principles
Common measurement principles include static laser light scattering (laser diffraction), dynamic image analysis (DIA) for shape and size determination, and classical sieve analysis. The different methods may have overlapping size detection ranges and complement each other in particle characterization.
Calibration and Maintenance
Regular calibration is essential for ensuring accurate measurement results and covers both optical components and software. Maintenance involves cleaning of optical systems and mechanical parts, as well as checking dispersing units if present.
Limits of Application
Particle analyzers are usually designed for defined particle size ranges and may have limitations depending on the measurement principle, such as with particle concentration, shape diversity, or sample composition. Additionally, sample preparation can influence the measurement process.
