Winner311 Spray Particle Analyzer

Product Overview:

Winner311A new-generation desktop spray particle size analyzer specifically designed for testing the droplet size of small spray devices, it integrates multiple micro-nano technologies, can be configured with an external automatic moving platform, features an optimized optical path design, wider distribution of detection channels, more stable algorithms, and enhanced intelligence in application.

Winner311This instrument can perform non-contact particle size measurements on dispersed droplets, liquid droplets, smoke, mist, and powder mist in the air. It also meets the national pharmacopoeia's requirements for particle size testing of inhaled aerosols, sprays, and powder aerosols, filling a gap in the measurement of droplet particle sizes in small atomizing devices using domestic laser particle size analyzers.

Product Features:

Advanced testing principles

The full range utilizes the principle of laser scattering/diffraction, determining the droplet size distribution by detecting the scattering spectrum of the mist droplets.

Exquisite structural design

The testing area employs a tubular open structure, featuring compact size, flexible installation, and convenient testing.

External Automatic Mobile Platform (Configurable)

Linked testing, test locations can be set with SOP, individually test samples at different distance points, one-click access, one-click reset, position memory, making testing more intelligent and convenient.

Airflow Protection Device

To address the issue of mist droplets easily polluting the lens during spray tests, Winano independently developed an airflow protection system, which effectively safeguards the lens and prevents mist droplets from contaminating it during the testing process.

New structure, new optical path, with higher testing accuracy 

Utilizing a single-beam parallel light path and dual-lens dual-array detector technology, the number of detectors has been increased, resulting in a more rational optical path layout. This ensures high-density collection of scattered light at various angles, expands the measurement lower limit, enhances the instrument's resolution, and guarantees accurate droplet size testing across the full range.

Instrument Test Report Description:

Vx: Particle diameter. The total volume of particles smaller than this particle size accounts for x% of the total volume of all particles.

Nx: Particle diameter. The total number of particles smaller than this particle size accounts for x% of the total number of particles.

VAD: Volume Average Diameter.

SMD: Surface Area Weighted Average Particle Size.

NAD: Number Average Diameter

R.S: Sample Dispersion Index, indicating the width of particle size distribution. The smaller the value, the more concentrated the distribution.

N/V: N50/V50, indicates the particle size distribution width. The closer the value is to 1, the more concentrated the distribution.

Volume/Quantity Distribution: Different statistical methods can be set for displaying in the analysis report under "Page Design" --> "Global Sequence."
