Articles from the CINRG technical team on automated particle counting, robotic Houillon viscometry, ISO 11171 calibration, and the realities of running a modern oil-analysis lab.
Most recent first. Each article is authored by Bill Quesnel or Alistair Geach — both with decades inside the commercial oil-analysis lab.
Why labs running portable particle counters — Beckman PODS, Hiac Royco, MP Filtra LPA, Diagnetics DCA — should consider stepping up to a fully automated benchtop instrument compliant with ASTM D7647.
How soft particles — water, varnish precursors, foam inhibitors, friction modifiers — skew optical particle-counting results, and what ASTM D7647 dilution methodology does about it.
Why traditional optical particle counters fail on water/glycol hydraulic fluids — and the dilution method we developed to make D7647-style counting reliable on these samples.
A look at how the 2015 NIST calibration-fluid revision shifted particle-count baselines industry-wide — and what the proposed ISO 11171 revisions do to keep historical data interpretable.
