WE have been getting some debris in out press hydraulic filter bowl. The particles are large (up tp 3 mm) and are non metallic: at lease they don't look like metal. They look like carbon partials. we need to know how what this is coming from, be it gasket, or plastic deterioration. Can someone recommend a analysis lab that can tell me where the heck this is coming from or what it used to be? This isn’t a job for normal oil analysis.

Analysts Inc is in Norcross outside of Atlanta. Good lab very helpfull. Google

Bill Herguth has sent me contaminant debris filtered from hydraulic fluid for analysis in the past. I analyze the particles using SEM/EDS methods.
