When the laser particle sizing results are different, it should be addressed as follows:
(1) If two instruments is different in theory, producing different results is normal as long as a relationship could be found between them.
(2) If two instruments use the same theory or from the same brand, the test conditions, including medium, dispersant, dispersion time, shading rate, sampling methods, should be unified first. Secondly, examine the status of the instrument, including the background, alignment, sample pool, refractive index, analysis mode, parameter settings, etc. If the results are still inconsistent, contact the manufacturers.
(3) Standard samples should be used to verify the performance of the two instruments.
(4) Send the sample to qualified and reputable third party institution for testing.
- If the two results are not very different and all are stable, the numerical corresponding relationship could be established.
