Instrument Introduction:

LA-960 laser particle size analyzer

Mainly used in the production and research of nanomaterials, ceramics, pigments, battery materials, chemical, petrochemical, pharmaceutical, cosmetics, food processing, and for quality management in accordance with GLP/GMP.

Performance characteristics:

1. Adopt the most accurate light scattering theory - Mie theory

The Mie scattering theory is a classical theory obtained strictly according to the mathematical solution of Maxwell's electromagnetic field theory, and is currently the most rigorous calculation method used in laser particle size analyzers. Therefore, using this calculation method provides a theoretical guarantee for the instrument to provide reliable data results.

2. Achieving a large detection range with a single measuring range

The range of LA-960 is 0.01um-5000um. The detection limit of 0.01um is currently the lowest detection limit achieved on laser scattering particle size analyzers. At such a low detection limit, LA-960 has a large dynamic response range, allowing the upper limit to reach 5000um. In addition, a single ultra large range allows users to avoid the trouble of switching ranges and replacing lenses when detecting samples with a large particle size range.

3. Highest guaranteed accuracy

The guaranteed accuracy of LA-960 is within ± 0.6% (for polystyrene standard particles), which is currently the highest among similar instruments; Ensuring reproducibility accuracy within 0.1% is also the highest in the industry.

4. Adopting a dual light source configuration to ensure full range detection accuracy

The LA-960 adopts a dual solid state light source - LD (650nm, 5mW) and LED (405nm, 3mW) configuration, ensuring sufficient scattered light throughout the full angle range, thereby ensuring ultra-high precision detection across the entire range. The first level solid-state laser light source provides extremely stable output for detection and has an extremely long service life. LED provides short wavelength light source and improves the detection accuracy of small particles on the ground.

5. Maximum number of effective detectors and optimal detector configuration scheme

The detector of LA-960 adopts the most advanced logarithmic cross arrangement scheme, with up to 87 effective detectors, which is currently the most effective detector of this type of instrument, thus achieving the highest resolution. Simultaneously configuring a lateral detector and a large angle (155 degrees) backward detector to achieve seamless detection in scattering space, ensuring the highest resolution, lowest detection limit, and maximum dynamic response range.

6. The most advanced optical system

The LA-960 adopts Horiba's unique overlapping anti Fourier optical system, and increases the scattering optical path by 4 times without increasing the instrument volume, thereby doubling the detection sensitivity while ensuring the reliability and stability of the optical path system. The entire optical system is installed on a rigid cast aluminum base, ensuring strong anti-interference ability and minimizing the impact of vibrations, temperature changes, and other factors on the optical system. The stability and reliability of the system are guaranteed, and the instrument is always maintained in the best detection state. In addition, the entire optical system does not require manual adjustment, completely avoiding the influence of human factors.

7. Powerful circulation, dispersion, and injection system

The LA-960 adopts a fully automatic built-in circulation, dispersion, and injection system, with the design striving for the shortest circulation pipeline. Therefore, on the one hand, it reduces the amount of dispersed medium required for detection (180mL-290mL), thereby achieving the goal of reducing the amount of sample required for detection; On the other hand, the shortest circulation pipeline can enable the sample to pass through the detection area the most times in the same detection cycle, so that the information of the sample particles can be reflected more fully. The use of a high output centrifugal pump (10L/min) ensures smooth and stable circulation of various particles, which guarantees excellent repeatability. The built-in ultrasonic dispersion head significantly improves the dispersion ability compared to traditional ultrasonic bath dispersion methods. The built-in automatic liquid addition pump can automatically add liquid at low, medium, and high levels, and is combined with a sample concentration monitoring system to automatically adjust the sample concentration, further improving the degree of automation and operation speed.

8. Pull out detection pool placement design ensures simple and accurate positioning of the detection pool, and easy and fast replacement

9. The fastest sampling and detection speed

The data sampling speed of LA-960 can reach 5000 times per second, which is currently the highest sampling speed. This ensures high-precision detection, so that any small changes in the sample can be captured. At the same time, it greatly improves the detection speed.

In conjunction with the injection system and control system, LA-950V2 can achieve the entire detection process of liquid addition, optical axis adjustment, blank filling, sample addition, bubble removal, detection, data display, saving, and printing within 1 minute, which is more than 5 times faster than the usual particle size analyzer detection speed.

10. Testing of absorbing materials

LA-950V2 uses relative refractive index as the detection condition input, which corresponds to the calculation requirements of Mie theory. Meanwhile, when inputting the relative refractive index, LA-950V2 allows for the input of imaginary terms, allowing for the determination of sample materials that absorb light.

11. Real time display of simple particle size distribution

When testing samples, LA-950V2 has the function of providing real-time simple particle size distribution of the tested sample before formal testing. By utilizing this feature, users can intuitively confirm the dispersion state of the sample in the circulation system before formal testing, thereby determining the optimal testing conditions.

12. Navigation function

The LA-960 has a unique navigator function, which allows even personnel who have never used the LA-960 to easily follow the clear instructions of the navigator for each step of the detection process. The navigator can also be used for standard program operation testing, namely SOP testing.

13. Adapt to multiple standards

LA-960 adapts to various international standards such as GLP, GPM, ISO, etc., fully meeting the consistency requirements of global enterprises in testing process conditions.
