ABSTRACT:
An improved method of producing a deposit of particles from a liquid medium carrier on a substrate for subsequent optical analysis of the particles, involves feeding the liquid medium carrying the particles to the substrate via a flexible tube which is not subjected to fluctuating lateral compressions. The invention has particular relevance to the making of Ferrograms from wear debris in a sample of machine lubricant.
