Abstract
A system for analyzing particles including: a source of solid particles; a sampler apparatus attached to and integral with the source of solid particles which apparatus is adapted to enable removal of small amounts of sample material from the source; a sonication cell connected to the sampling apparatus which sonication cell receives, optionally conditions, and sonicates the small amounts of sample material; a sample analysis apparatus connected to the sonication cell which sample analysis apparatus is adapted to receive, optionally further condition, and analyze the resulting sonicated sample received from the sonication cell; and a liquid pump and liquid carrying lines adapted to: withdraw aliqouts from the source; convey a withdrawn aliqout to the sonication cell and sample analysis apparatus; and flush the system free of residual aliqout contamination.
