ABSTRACT:
A laser scattering particle-sized distribution analyzer includes a rotary table for movably supporting a plurality of sample cups. A camming mechanism associated with each sample cup holder can be activated to invert a sample cup at a discharge station. Diluting fluid can be sprayed into the inverted cup to ensure a complete discharge of the sample. The sample is then appropriately mixed to ensure the creation of a homogeneous sample with sufficient diluting fluid and delivered to a sample cell for measurement with the laser and detector system.
