Product Description

Imported He-Ne laser emitter particle size analyzer with Mie scattering

LS-POP (9) is a new cost-effective laser particle size analyzer designed and manufactured by NANBEI relying on powerful R&D managerial experience from Spectris and combining the market application features of LS-POP(6)- the star product and sales champion at present after NANBEI joining in UK Spectris plc. It will bring a feeling of freshness to powder industry with higher testing performance.

Applications: Measure the particle size distribution of powder or latex. Principle:Light is an electromagnetic wave. When light meets with particles on it way of traveling, the interaction between light and particles will result in deviations of part of the light, which is called light scattering. The bigger the scattering angle is, the particle size will be smaller, the smaller the scattering angle is, the particle size will be bigger. The particle analyzer instruments will analysis the particle distribution according to this physical character of the light wave.

Technical features

1.Reliable optical platform 1.1.Use horizontal straight light path layout, no reflecting prism, light path is stable and reliable. 1.2.Good designability for base, good consistency of light path. 1.3.GB/T4857.18 drop test has been passed. 1.4.Laser power module uses irrigation methods for sealing, good moisture resistance. 1.5Modular construction design, maintenance is more convenient. 1.6The all-in-one housing design, it’s dust-protected and water-proof.

2. Optimized light path structure

Schematic diagram of optical path

2.1.Light path adopts lens back Fourier transform structure.

2.2.Optical source adopts He-Ne laser emitter which owns better monochromaticity, high coherence, small divergence angle and good stability compared to other laser emitters, we also adopt the patent design of integrated laser emitter(patent no.: 00228952.0) which reduces heat distortion of laser tube and external mechanical vibration.

2.3.For laser emitter, except for traditional detection of output power value, we add the stability test of output power.

2.4.Smoothing processing technology is used to reduce the impact of power fluctuation to measurement. 2.5.Backward detector is added, the lower limit of measurement is extended to 0.1micron. 2.6.Detector array adopts unique scattered light detection around a sphere surface (DAS) (patent no.: 95223756.3), the large angle detectors are placed in a spherical surface to get accurate focus of the large angle scattered light.

3. Advanced data collection and processing technology 3.1.Using 8-channel simultaneous sampling to sample 16 bit ADC, the sampling frequency of frame data can reach

1 kHz.

3.2.Using 64-channel simultaneous sampling technology and sample & hold switch with ultralow leakage current, the full scale accuracy can reach 0.15%.

3.3.Offset function of electric background, it can help to get more accurate optical energy data. 3.4 Data collecting board adopts 32 bit CPU which is manufactured by famous ARM Company, it owns high-efficiency signal processing capacity and low power consumption.

4. Friendly & practical software Functions:

4.1.SOP standardization operating procedure function, analysis & testing process standardization 4.2.Multiple distribution models：Rosin-Ramler mode, general mode, enhanced mode, Single mode 4.3.Multiple report models：General purpose, sieving, percentage, average, statistics and fitting reports 4.4.Two accumulative directions: small to large, large to small 4.5.Reports in two languages：Chinese, English 4.6.Reports can be exported as PDF, Excel format or other text format files 4.7.Multiple reports can be opened at the same time, easy to compare among reports 4.8.Report items can be revised according to different industries’ requirements, also can be set as fixed report format

. 4.9.Complete, open database of sample material, owns more than 200 kinds of commonly used material parameters. Users can define refractive index parameters by themselves, including real part and imaginary part (correspond to the absorption of sample).

4.10.Automatic clear of electric background.

5. Sampling system and its technical features

SCF-105B Circulating Sample Feeding System

5.1 Technical features of SCF-105B Circulating Sample Feeding System
