ASTM D7647 compliance, on-site calibration, and integration with modern LIMS platforms. https://cinrg.com/blog-ghost-particles.html https://cinrg.com/blog-ghost-particles.html Thu, 23 Nov 2023 00:00:00 GMT Bill Quesnel Particle Counting Soft particles How soft particles — water, varnish precursors, foam inhibitors, friction modifiers — skew optical particle-counting results, and what ASTM D7647 dilution methodology does about it. CINRG laboratory studies show 75/25 toluene/IPA dilution restores accurate ISO 4406 codes. https://cinrg.com/blog-water-glycol-method.html https://cinrg.com/blog-water-glycol-method.html Mon, 05 Jun 2023 00:00:00 GMT Bill Quesnel Methodology Fire-resistant fluids Why traditional optical particle counters fail on water/glycol fire-resistant hydraulic fluids — and the dilution method CINRG developed to make D7647-style counting reliable on these samples. https://cinrg.com/blog-2806-standards.html https://cinrg.com/blog-2806-standards.html Sun, 08 Jan 2017 00:00:00 GMT Alistair Geach Calibration Standards NIST SRM 2806 A look at how the 2015 NIST SRM 2806b calibration-fluid revision shifted particle-count baselines industry-wide, and what the proposed ISO 11171 revisions do to keep historical data interpretable.
