Laser Particle Size Analyzer
LS-609 Laser Particle Size Analyzer
LS-609 is a laser particle size analyzer for the measurement of particle size distribution of dry samples within the size range 0.1 - 1000 microns Based on Laser Diffraction principles, the LS-609 makes use of a high performance He-Ne laser light source which is more stable and has lower warm-up times than systems using traditional lasers. Full automatic alignment of the laser and detector, the LS 609, through an intuitive software interface, allows both SOP driven or manual measurement protocol's.
Coupled with an automatic sample dispersion device utilizing variable control of pump sped stir speed along with variable ultrasound capability, allows making measurements simpler and more efficient for materials such as Minerals, Cement, metal powders.
Laser diffraction analysis is based on the Mie Theory & Fraunhofer approximation, stating that the angle of scattered light by a particle is directly proportional to the particle size.
The angle of the laser beam and particle size have an inversely proportional relationship, where the laser beam angle increases as particle size decreases and vice versa.
Laser diffraction analysis is accomplished via passing particles suspended in a liquid medium contained in a measurement cell through a He-Ne laser. As the particle pass through the laser they "scatter light " at a certain angle. This angle is recorded on a detector which is then converted into particle size and size distribution based on Mie Theory. Resulting data is then displayed graphically through the appropriate operating software.
A lens is placed between the object being analyzed and the detector's focal point, causing only the surrounding laser diffraction to appear.
The LS-609 utilises a fully comprehensive and professional software package running on Windows 7 (32 bit) operating system and above. A simple, English Language, user friendly interface allows an SOP, or manual driven measurement process, where all aspects of the measurement and subsequent result calculation & reporting are controlled. A simple and concise software menu, driven by, simple and easy to understand "icons" is utilised for all major functions and processes such as cleaning, setting up SOP, database access or search.
Fully automated measurements with full control over pump speed, sonication, measurement parameters such as duration & cleaning procedure as well as sample loading and alignment procedures.
Whilst of course manual measurement is available many users prefer to use SOP'S ( standard operating procedures ). These SOP's are designed in advance and take care of all key parameters in the various measurement steps. SOP driven measurements reduce greatly the error in a measurement by ensuring same parameters are used each time.
A comprehensive and expandable built-in database is provided for storing all measurement records and data allows fast retrieval and various reporting possibilities and result calculations including, result overlays and average record results.
Results can be presented in many formats such as trends, single page volume reports or even overlays. Additional report formats such as Sieve data can also be produced directly within the software. The user also has the possibility to make "custom" reports allowing complete freedom of what parameters are required for reporting.
Additional capability for exporting data in .pdf formats or to external software such as, Excel is also possible. Additional features allow the calculation of raw data using other algorithms such as "enhanced " or "single peak " mode.
The LS-909II is a new generation of laser diffraction particle size analyzer developed and manufactured by OMEC Instruments, Zhuhai. This instrument is engineered to meet customer demands for a high-performance system capable of supporting both wet and dry dispersion methods.
Designed to deliver premier performane at an affordable cost, the LS-909II makes advanced particle sizing technology accessible to a wide variety of users. Key advantages include:
The LS-909II utilizes advanced laser diffraction technology to measure the size distribution of particles. The angle of the laser beam and particle size have an inversely proportional relationship, where the scattered light angle increases as particle size decreases and vice versa.
When a laser beam passes through the dispersed particles, the instrument records the intensity of the scattered light. It then evaluates the resulting scattering pattern using Mie or Fraunhofer scattering theories to compute the exact particle size distribution. Resulting data is then displayed graphically through the appropriate operating software.

The Topsizer is a high-performance laser diffraction particle size analyzer developed and manufactured by OMEC Instruments, Zhuhai. Evolving from 30 years of continuous technology development, the Topsizer offers wide size ranges, excellent reproducibility, high levels of accuracy, exceptional reliability of results, and a high degree of automation for particle size distribution analysis. As an established industrial standard renowned for its high quality and outstanding performance, the Topsizer provides a critical competitive edge across manufacturing quality control and demanding research environments.
The Topsizer utilizes advanced laser diffraction technology to determine the exact size distribution of particles. During analysis, a coherent laser beam penetrates through the optimally dispersed sample particles, causing light scattering.
The integrated multi-dimensional detection system records the exact angular intensity distribution of the scattered light. Using these scattering patterns, the software computes particle characteristics based on robust Mie scattering or Fraunhofer diffraction theories, ensuring high-fidelity measurement resolution from submicron ranges up to millimeter scales.
