Laser Particle Size Analyzer LLPA-D10

Labtron laser particle size analyzer operates on the principle of laser diffraction, where a laser beam passes through a dispersed sample of particles. As the laser encounters particles, it is scattered at different angles depending on particle size—larger particles scatter light at smaller angles, while smaller particles scatter at wider angles. Detectors placed around the sample measure the intensity and angle of scattered light. The system then uses mathematical models like Mie or Fraunhofer theory to calculate particle size distribution. This non-destructive, high-speed method allows for accurate measurements across a wide size range. It is suitable for both wet and dry samples. The data is displayed in volume, number, or area distribution formats depending on user needs.

Labtron’s laser particle size analyzer can measure a wide variety of sample types including powders, suspensions, emulsions, aerosols, and even gels. Commonly analyzed materials include pigments, cement, ceramics, pharmaceuticals, polymers, food particles, and metal powders. Depending on the dispersion system, the instrument may support both wet and dry modes, allowing flexible sample preparation. Some analyzer include built-in ultrasonic dispersion units to break down agglomerates in liquid samples. Dry dispersers may include controlled airflows for gentle or aggressive dispersion. It’s important to match the sample type with the appropriate dispersion method to ensure accuracy. Proper pre-treatment of the sample can further enhance reliability and repeatability.

Labtron laser particle size analyzer are used in various industries, where particle size impacts product performance, quality, or compliance. In the pharmaceutical sector, they help ensure uniformity in active ingredients for effective drug delivery. In cement and construction, particle size affects material strength and setting time. In food processing, they control texture and solubility. Cosmetics rely on consistent particle size for smoothness and absorbency. Paints and coatings need precise particle sizes for coverage and stability. Environmental testing, metal powders, ceramics, and chemical manufacturing are other major applications. The analyzer versatility and speed make it an essential tool for both research and production.

Labtron supplies advanced laser particle size analyzer. Repeatability and accuracy in laser particle size analysis are maintained through a combination of high-quality optics, precision detectors, stable laser sources, and intelligent software algorithms. Repeatability is often ?0.5–1%, indicating consistent results across multiple measurements. Accurate sample dispersion-whether through ultrasonic agitation or air dispersion—is crucial to avoid agglomeration. Calibration with certified reference materials is recommended for verifying accuracy. Environmental factors like vibration and ambient light are minimized using enclosed optical paths and vibration-dampening mounts. Software features like background subtraction and auto-alignment further enhance consistency. Regular maintenance and calibration also play key roles in sustaining long-term performance.

Proper sample preparation is critical for accurate and repeatable results. For wet analysis, samples must be uniformly dispersed in a compatible liquid medium, often with the help of ultrasonic agitation to break apart agglomerates. Surfactants may also be added to prevent re-clumping. In dry mode, powders should be free-flowing and may require sieving to remove oversized particles or foreign debris. The goal is to isolate individual particles without altering their structure. It's important to use clean dispersion units to avoid contamination from previous samples. Overloading the sample chamber can distort readings, so follow volume guidelines carefully. Consistent preparation techniques lead to more reliable comparisons across multiple tests.
