1. The inverted Fourier optical system is adopted to greatly reduce the stray light generated by multiple reflections of the sample pool and the optical mirror. The large-angle scattered light is not limited by the lens aperture, which effectively improves the test resolution and ensures the accuracy of the test data.
2. 128-level multi-element detector completes the reception of forward, side and backward scattered signals. The scattered signal detection is fine and the detection resolution is high.
Each level of the detector background light is independently compensated, and the highest gain is achieved. The signal is collected and amplified at a high speed, the dynamic response is sensitive and fast, and the optical path center self-check is completed at the same time.
3. Imported semiconductor laser, dual light source test resolution is higher, the main light source wavelength is 650nm, 30mw, and the life is >70000h. The auxiliary light source wavelength is 405nm, 20mw, and the auxiliary light source enhances the resolution of the small particle size range.
4. The high-rigidity optical structure of the elastic support and the stable optical path ensure that the instrument is in a stable state for a long time.
5. The sample detection optical dish is made of high-quality high-optical glass glue to ensure optical accuracy and mechanical strength.
Integrated design, no need to disassemble
The instrument adopts an integrated design with a simple appearance. The circulation sampling system is inside the instrument. You only need to add samples to the sample pool to automatically complete the test. The large-diameter ultrasonic dispersion pool and the stirrer mix evenly and quickly, so that the sample is fully dispersed and the bubbles are discharged quickly. The peristaltic pump circulates for short distances to avoid sample stratification. The peristaltic pump directly squeezes the pipeline to transport the liquid, which is highly efficient. All pipelines are of equal cross-section and flow rate, without centrifugal negative pressure area, with little contamination to the sample and easy cleaning. There are no bubbles during transportation. The accuracy and repeatability of the instrument test are guaranteed.
Perfect preparation system
It has intelligent functions such as automatic water absorption, automatic centering, automatic testing, automatic cleaning, and ultrasonic anti-dry burning. The unique fully automatic sample mechanical stirring motor device can fully disperse the sample while reducing bubbles and liquid splashing, ensuring stable and reliable test results.
Stable dispersion system
The standard sample pool with a volume of 500ml is made of 304 stainless steel, which is durable and corrosion-resistant. Built-in automatic water suction pump, water can be automatically added without manual operation. A water level detector is installed above the sample pool. When the water level reaches the specified height, the electromagnetic valve automatically closes to ensure the accuracy of each test medium. Because dispersion and circulation are completely independent, the cycle test time is short, which reduces the sample's adhesion, contamination and wear on the optical test dish, and improves and extends the service life.
