LPA-6000DW Laser Particle Analyzer Dry & Wet Dispersion 0.01µm - 3000µm

LPA-6000DW Dry & Wet Dispersion Laser Particle Size Analyzer

Product Description

The LPA-6000DW laser particle size analyzer is a high-end dual-purpose laser particle size analyzer integrates a dry dispersion system and a wet dispersion system, and is a dual-purpose machine. The wet dispersion system can test conventional powder and slurry samples, and the dry dispersion system is suitable for testing magnetic materials, medicinal powders and easily soluble samples. Dry or wet testing, no need to change the device, just select dry or wet in the software test menu to quickly achieve function conversion. The instrument is suitable for particle size distribution testing of micron-level powder materials.

The LPA-6000DW laser particle size analyzer has an advanced optical design, and uses the Fourier lens automatic centering system and the inverted Fourier optical system. It is calculated according to standards such as GB/T19077-2016 ISO13320 and the (unconstrained) free distribution mode of Shuoboda. 128-level multi-quantity detectors ensure that each level of particle size reaches the highest resolution, fully detect the subtle differences in the details of each particle level, and quickly obtain accurate and reliable particle size distribution data. It has the advantages of repeatability, stability, and high resolution.     

LPA-6000DW works with both wet and dry dispersing systems

—The dry system includes host,auxiliary equipment( including vacuum, waste powder collecting can, air purification tank) and quiet air compressor.

—The wet system includes ultrasonic dispersion, mechanical agitation, circulation etc.

—Just click the mouse to shift between liquid and dry without manually replacing the device in order to secure the accuracy and repeatability.

—Dry method or wet method test, no need to change the device, just select dry method or wet method in the test software menu, and the function conversion can be quickly realized. The instrument adopts a metal shell fully sealed structure, which has good electromagnetic shielding performance, and can achieve environmental protection and no pollution in the test, quickly obtain accurate and reliable particle size distribution results, and have the advantages of repeatability, stability, and high resolution.

Applications

Advanced optical system

Inverting the Fourier optical system greatly reduces the stray light generated by the multiple reflections of the sample cell and the optical mirror. The large-angle scattered light is not limited by the aperture of the lens, which effectively improves the test resolution and ensures the accuracy of the test data. accuracy.

128-level multi-element detectors, each level of background light is independently compensated, and the gain is increased. 

Imported semiconductor laser, dual light source test resolution is higher, main light source: wavelength 650nm, 30mw, lifespan> 70000h.

Auxiliary light source: wavelength 405nm, 20mw. The auxiliary light source enhances the resolution in the small particle size range.

The high-rigid optical structure supported by elastic, the optical path is stable, and the instrument is guaranteed to be in a stable state for a long time.

The sample detection cell is glued with high-quality high-optical glass, and the metal material on both sides is reinforced (patented) to ensure the highest optical precision and mechanical strength, and a long service life.

Dry dispersion system

Ÿ The dry test system consists of a main machine, auxiliary machines (built-in dust extraction system, dust storage waste tank, compressed air purification tank), silent air compressor and other parts, with automatic sampling, automatic dispersion, automatic testing and other functions.

Ÿ Dry sampling system - dispersion powder spraying device, the sampling inlet is directly integrated with the spray gun, the transmission distance is short, and the samples are all quickly and continuously dispersed to the detection area automatically during the movement of the sample tank, without stratification and adhesion, ensuring the accuracy and stability of the test.

Ÿ After the test is completed, the working chamber is automatically cleaned, and the waste is automatically collected into the auxiliary machine storage tank, which is not only recyclable for precious powder but also environmentally friendly and pollution-free. The test process is fully automatically completed under computer control, with a high degree of intelligence, and the results are automatically recorded and saved by the computer.

Wet Dispersion System

Ÿ Wet method fully automatic circulation system - The wet method system consists of ultrasonic dispersion sample pool, mechanical agitator, circulation and other parts. It has functions such as automatic water absorption, automatic centering, automatic testing, automatic cleaning, water level overflow prevention, ultrasonic anti-dry burning prevention, etc. The built-in automatic water suction pump can automatically fill water without manual operation. A water level detector is installed above the sample pool. When the water level reaches the specified height, the electromagnetic valve closes to ensure the accuracy of each test medium.

Ÿ When the sample is added, the large-diameter ultrasonic dispersion pool and the agitator work at the same time to ensure that the sample is quickly and evenly dispersed. The peristaltic pump circulation pipelines are all equal-section and equal-flow, without centrifugal negative pressure areas, easy to clean, no bubbles during transportation, and short-distance circulation, which effectively avoids sample agglomeration and ensures the accuracy and repeatability of the test.

Versatile analysis software 

Ÿ One-key exchange of Chinese and English operating systems, the software interface is clear and clear, and the operation is simple.

Ÿ There are three formats of report output: free distribution, normal distribution, and RR distribution to choose from. The content includes cumulative particle size distribution data and curve, interval particle size distribution data and histogram, typical particle size values such as D3, D10, D25, D50, D75, D84, D90, D97, volume average particle size, area average particle size, specific surface area etc. data.

Ÿ Test data can be viewed online, printed, or saved in PDF format.

Ÿ Adopt RS232 and USB standard serial data transmission mode.

Ÿ The analysis software is compatible with Windows XP/Win7/Win10 systems.

Operating environment

Ÿ Environmental requirements: Relative humidity less than 85%, no condensation.

Ÿ Other requirements: Clean environment without smoke and dust, no mechanical vibration source or electromagnetic interference source around.
