PORTABLE PARTICLE ANALYSERS |
摘要 |
A portable particle analyser is compact and can determine the size, geometry and number of particles in a sample of fluid. A laser beam 15 intercepts the flow of fluid 17 at the first focal point of a parabolic mirror 11. Light is scattered and collected by radiation collectors 13 and low angle scattered radiation is detected in a second chamber 19 by reflection by an ellipsoid mirror 20 towards a radiation collector 21. Photomultiplier units 23 convert the radiation collected into electrical signals for analysis. |
