For large particles, they can be dispersed by the gravity of the particles themselves. New Patek Company can provide a dry gravity dispersion laser particle size analyzer (model: HELOS/GRADIS， Test range: 0.5-8750 micrometers).

Example:

Comparison of dispersion test results of HELOS&RODOS: NdFeB dry wet method using dry laser particle size analyzer:

　

1. Dry sample testing does not require any dispersants or solvents;

2. Instantaneous dispersion and measurement, fast testing accuracy, high analysis efficiency, and only a few seconds from sample injection to result output;
3. Sample sizes ranging from milligrams to kilograms can be tested each time;
4. Easy control of dispersed energy (dispersed pressure can be adjusted between 0.1-6Bar according to material characteristics);
5. A uniquely designed decentralized system with self-cleaning function, which does not require disassembly for cleaning and can continuously test many different materials without causing cross contamination. The system automatically recovers waste materials, which is conducive to environmental protection and reuse;
6. Powerful operating software with multiple report formats to choose from. Test results can be compared on the same interface, and customers can customize report formats, including FDA CFR 21 Part 11 Model;
7. The main body and casing of the instrument are all made of high-quality stainless steel, which is durable and long-lasting
