How to test a few large particles of samples with laser particle size analyzer
 
For the same volume of the particle size, their optical concentration ratio of the particle size ratio is 1/1000, if looking for 1-2 large particles in a large number of small particles, because the probability of large particles present in the detection zone is minimal, so it is more difficult to detect them. Solution to the problem can be taken step 2, 
1, the sample was divided into two parts by the sedimentation method, test for times, the larger particles individually tested, can improve the resolution of the instrument. 
2, Combine the 2 test results. Note that you must consider solid ration of samples in the 2 test, and then combined results is effective,winner software companies have this funtion, simple operation, can accurately test the content of a few large particles.
