LDY2308 measure powders dispersed in liquids and air with a broad measurable range (0.5-2000um). Under automatic and intelligent control it is particularly suitable for the study of unknown particles, particle mixtures and particles with wide size distributions.
Main Features:
- Principle: Particles of different sizes scatters the illuminating laser into different patterns. In this instrument He-Ne laser is used to illuminate and photon detector arrays measure the forward, sideward and backward scattered laser. Software automatically converts the patterns into size distributions.
- Novel technique: It uses a patented technique of Fourier transform of converging light, the technique of spectrum amplication and the design of perpendicular light paths. Photon detector arrays measure the forward, sideward and backward scattered laser. This ensures the precision and reproducibility of the measurement results obtained from nano-particles.
- Unconstrained data fitting program: the particle analysis software uses a unique unconstrained data fitting technique that we developed to intelligently measure an unknown size distribution, this is particularly important for material researchers, or for measuring particle size distributions with multiple peaks in data.
Dispersing system:
- Wet dispersing: We carefully aligned the stirring set-up, the ultrasonic dispersing unit and the sample circulation pipes, and fixed them inside the instrument. Such a built-in design effectively prevents the inhomogeneous dispersion and sedimentation of big particles, which can be observed in the designs that these dispersing units are separated from the instruments, where the sample circulation pipes are therefore too long.
- Dry dispersing: A patented turbulence dispersing technique thoroughly mixes the samples and air. Key parts of the dispersing system are made of wear-resistance ceramics to improve the service life, and to guarantee the reliability of the results.
Intelligent measurements:
- The wet/dry measuring modes can be switched by just pressing a key. There is no need to do any other operations, like changing channels which are necessary in other wet/dry double modes instrument
- Users only need to add in their samples, and click the 'automatically measure', and then all the procedures, including pumping in water or air, dispersing, circulation, measuring, cleaning, data recording, analyzing, saving and printing etc. are automatically executed. This reduces users' workload, as well as minimizes any possible errors resulted from manual operations.
- Rich software functions: Beside the basic function of analyzing the size distributions, the software also has the following features:
The output has rich content including: size distribution, R-R distribution, logarithmic distribution, statistics within different size ranges, volume distribution, number distribution, the percentage of particles of a certain size, or a certain size range, and comparison of multiple results. - The output could be in Word, Excel, Bmp pictures and Text formats, and this makes easy viewing and referencing the results at different situations.
- It supports English and Chinese languages, and it can be changed to many other language versions according to the user's needs.
- Automatic alignment: A precise four phase hybrid stepping motor automatically aligns the optical path and can adjust it at any moment. This releases users from manual adjusting the optical path and improved accuracy and stability of the measurement results.
- Calibration: Throughout the measurable size ranges the instrument is calibrated with China's standard reference particulate materials. The resolution and accuracy are guaranteed.
