TONGNIAN Joins the Drafting Group: National Guide to Exosome Particle Size and Concentration Measurement (2026 No.17)
The national Guide to Exosome Particle Size and Concentration Measurement (2026 No.17) — the methodology standard for particle-sizing and concentration release testing — lists TONGNIAN among its drafting contributors.ncentration Measurement* (2026 No. 17) — the measurement methodology standard for exosome particle sizing and concentration release testing.
What drafting participation means for buyers. When your supplier sits inside the drafting group, two things follow. First, your COA speaks the standard's measurement language: size-distribution and concentration values comparable across batches and, as adoption spreads, across suppliers. Second, method changes reach you through the drafting cycle, not through surprise spec revisions.
The standard anchors our release panel: NTA with TEM morphological cross-check for size distribution, NTA for concentration, executed per batch with retain samples kept. Together with our MISEV2018-aligned characterization logic, this is why a TONGNIAN COA reads the same way, batch after batch.
The full standard text and our characterization baseline are available on request — use the Request a Quote form and we will send both with your sample references. Request a quote.
