Winner311PRO Spray Particle Analyzer

Product Introduction:

Winner311PROA new-generation desktop spray droplet particle size analyzer designed and developed primarily for testing the droplet size of small spray equipment.Winner311XPOn this basis, it integrates more micro-nano proprietary technologies, intelligent and modular instrument design, dedicated electric test benches, compatible with various atomizers; equipped with a high-speed data acquisition system, rapid data collection and analysis; the software adds commonly used GMP functions in the pharmaceutical industry, making the application more intelligent.

Winner311PROThe instrument can perform non-contact particle size measurements on airborne droplets, liquid droplets, smoke, mist, and powder mist, and also meets the national pharmacopoeia requirements for particle size testing of inhaled aerosols, sprays, and powder aerosols, filling the gap in domestic laser particle size analyzers for measuring droplet sizes in small atomizing devices.

Product Features:

Advanced testing principles

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

Exquisite structural design

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

Intelligent and modular design

Specialized electric test bench, featuring SOP settings for test positions, software location memory function, allowing separate testing of samples at various distance points, achieving automatic arrival at test positions, reducing testing errors caused by inconsistent manual holding, one-touch arrival, one-touch return, making testing more intelligent and convenient.

Lens Protection, Sample Testing Vacuum Drainage Device

To address the issue of spray tests where droplets easily contaminate the lens, MicroNano has independently developed an airflow protection system that effectively safeguards the lens, preventing contamination during the testing process. The addition of a vacuum-assisted sample testing device, with adjustable vacuum, caters to the atomization testing needs of various atomizing equipment.

New structure, new optical path, higher testing accuracy 

Utilizing a single-beam parallel optical 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 from various angles, extends the measurement lower limit, enhances the instrument's resolution, and guarantees accurate droplet size testing across the entire measurement range.

Instrument schematic diagram:Instrument Test Report Description:

Vx: 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 diameter constitutes x% of the total particle count.

VAD: Volume-Averaged Diameter.

SMD: Surface Area Weighted Average Particle Size.

NAD: Number Average Diameter

R.S: Sample Dispersity 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: Set the display in the analytical report for different statistical methods under "Page Design" --> "Global Order".
