Brief introduction
BT-2800 dynamic image particle size and shape analysis system adopts sheath technology, it has the functions of stirring, ultrasonic dispersing, etc. Just put the sample into the beaker for making suspension liquid in definite concentration, and particle size analysis could be carried out. When shoot the images, the computer recognizes and processes the particles quickly in the meantime, and the screen displays the images, particle size and particle shape data for each particle in real time. Analysis results includes L/D ratio and circularity for reflecting particle shape, particle size distribution, typical value and the largest particle value for reflecting particle size, specific interval contents, contents of less than or more than a definite particle size, specified equivalent particle size, etc. The system has the characteristics of imaging clearly, fast analysis speed, easy operating, accurate and reliable result, etc. It provides a high precision analysis method for study, production and application of abrasive, medicine, high performance metal powder materials, battery materials, rod-like and acicular materials.

1. Size Range: 4-400 um
2. Magnification: 5-35 X
3. Maximum resolution: 0.5 um
4. Repeatability: < 1%
5. Accuracy: < 1%
6. Test items: (1) particle size: Particle size distribution, typical value, maximum particle size, specific interval content, content of particle that is bigger than or less than a certain size. (2) Particle shape: Length to diameter ratio and its distribution, circle fit and its distribution, particle image. (3) Particle counting: Measuring the number of particles in a specific volume of liquid.
7. Output items: Original parameters (including sample information, test information, etc. ), analyzed data (including particle size distribution, distribution of the length to diameter ratio, distribution of circle fit, and its typical data, etc. ), distribution pattern (interval distribution histogram and cumulative distribution curve, etc. ).

1. Calibration method: Shoot an image for actual microscopic scale, and open this scale image with software, draw a line at the specified scale range, calculate the actual length corresponding to a pixel, and then convert the pixel into actual size while test and analysis.
2. Fluid focusing and imaging principle: Two flow paths are designed in the tube, one is a sample flow, and the other is a sheath flow, as shown in figure below. Align the sample tube with sheath tube to spray the sample. The sample with sheath flow all round it goes together through the shooting area. Sheath fluid around the particles forces particles in a queue. High speed camera shoots pictures for particles queue which going through the shooting area. As particles queue just lies in the focal plane of the lens and has no defocus phenomenon, the very clear particle images are obtained. In the process of imaging the particles, computer will rapidly recognize and process the particle images at the same time. Images and particle size and shape data for each particle will be displayed on the screen on real time basis.

Good repeatability
Reasons for good repeatability:
Laser, detector and signal transmission system are stable and reliable.
Stable and effective dispersing system.
High-speed sampling system keeps the instrument always in optimum condition.
Sampling rate can reach 3500 times/second, and mass data can effectively reduce the influence of repeatability caused by little abnormal data.

Kindly reminder:
Repeatability is primary index of particle size analyzer. It is worthless for particle size analyzer if repeatability is not good. Repeatability is related to the instrument, also, related to the operator, voltage, water quality and interference. It is a reflection of integrated factors.

Good accuracy

Reasons for good accuracy:
Adopts high speed CCD, which can shoot 100 images per second, and can analyze more than 10 thousand particles per minute.
Through the scale to calibrate the accuracy of the system, so analysis result is accurate and reliable.
Complete sample preparation, and has the functions of stirring, dispersing and so on. Adopts fluid focusing technology, precision plunger pump technology, fast recognition technology of particle image, etc.
To filter agglomerate or adhesive particles through the function of recognizing connected particles, in order to avoid that the test result is affected.
