Guide and selection support
Dry particle analysis enables precise characterization of particle size, shape, and other attributes such as charge and color in dry samples, supporting research and production needs. It is widely used in the chemical and pharmaceutical industries for quality control and process optimization.
When selecting suitable systems, key factors include the measurement range, the measurement principle, as well as requirements for sample preparation and dispersibility. Additional features such as dispersion units can affect measurement quality.
LabFinder provides an overview of suitable solutions for dry particle analysis and assists users in navigating and comparing relevant measurement systems for different applications.
Applications and Benefits
Dry particle analysis encompasses techniques for determining particle size, shape, and other properties of solid particles in dry samples. It is an essential part of material characterization in sectors such as chemicals and pharmaceuticals, where product quality and process efficiency are closely linked to particle properties. Typical use cases include powder characterization, dust measurement, and the control of granulates.
Selection Criteria
Key factors in selecting a system for dry particle analysis are the required size detection range, measurement accuracy, and the underlying measurement principle. Compatibility with the sample material, ease of handling, and the need for sample dispersal should also be considered. Interfaces for data evaluation and integration into existing laboratory systems are important as well.
Variants and Measurement Principles
Common methods include static laser light scattering (also known as laser diffraction), dynamic image analysis (DIA), and classical sieving analysis. Each method covers characteristic particle size ranges that may overlap. Laser light scattering is suitable for wider size distributions, dynamic image analysis can also determine particle shapes, and sieving analysis is well suited for coarser particles.
Calibration and Maintenance
Regular calibrations are necessary to ensure measurement accuracy and obtain reproducible results. Maintenance tasks may include cleaning optical components or inspecting mechanical parts. Depending on the system, dispersion units must also be maintained to ensure consistent sample preparation.
Limitations of Application
Dry particle analysis is less suited for moist or dispersed samples, as these may require different measurement techniques. Highly agglomerated samples can lead to inaccurate results, making proper sample preparation crucial. The availability of appropriate measurement ranges for each method also limits the detectable particle sizes.

Frequently asked questions
How does dry particle analysis basically work?
Dry particle analysis measures the size and often also the shape of solid particles in dry samples using optical or mechanical methods, such as laser light scattering, imaging techniques, or sieving analysis.
Which methods are used for particle analysis of dry samples?
Common techniques include static laser light scattering (laser diffraction), dynamic image analysis for determining shape and size, and classical sieving analysis for separation by particle size.
What criteria are important when selecting a particle analysis system?
Important factors include the measurable size range, measurement accuracy, the measurement principle suited to the sample material, ease of operation, as well as requirements for sample preparation and data integration.
How is calibration and maintenance performed for dry particle measurement instruments?
Regular calibration using reference standards ensures accurate measurements. Maintenance includes cleaning optical components, checking mechanical function, and servicing any dispersion units.
What are the limitations of dry particle analysis?
It is less suitable for moist or highly agglomerated samples. Additionally, each method has a limited measurement range, so extremely small or widely varying particle sizes may not be detected.
