  • Qt 1 Laser Particle Size Analyzer - China

    price: contact company for price

    Principle of operation

    The QT-1 laser particle size analyzer uses Mie scattering theory to measure particle size, considering the refractive index of the particles and dispersion medium. According to Mie’s theory, a particle will scatter light at an angle determined by that particle’s size. A collection of particles will produce a pattern of scattered light defined by intensity and angle that can be transformed into a particle size distribution result. The data of particle test can be calculated in two ways: unconstrained fitting inversion and constrained fitting inversion. The constrained fitting inversion is a relatively simple way. The particle size distribution is inverted with the assumption that there is a certain distribution pattern in particles. However, the deviation exists between the assumption and the reality. Therefore, the tested results through the constrained fitting inversion cannot truly reflect the real size distribution of the particles. In unconstrained fitting inversion, no distribution pattern of particles is assumed before the test, and the size distribution of the particles is directly and precisely calculated from the light intensity. In this way, the instrument requires reasonable sensor design and size grading to ensure its high performance. The particle size distribution can be precisely calculated with QT-1 Laser particle size analyzer which uses the optimized non-uniform cross 3D fan-shaped sensor array and the reasonable size grading.

    QT-1 Laser Particle Size Analyzer


    Measurement range:0.05 ~ 800 µm
    Accuracy:<±1% (Chinese National Standard D50)
    Repeatability error:<±1 % (Chinese National Standard D50)
    Power supply:220±10V AC, 50Hz, 200W

    Technical features

    Stable performance: The stability of the tested data is ensured by the stable optical signals from the system. The QT-1 Laser particle size analyzer uses He-Ne gas laser light source with 0.6328 micron wavelength. It can offer stable laser source signals, and serves more than 15000 hours.

    Reliable data: The reliability of the tested data requires stable light signals from the system. The real results require high dispersion effect of the tested samples as well as even distribution of the tested dispersed liquid.
