Frequently asked questions
What is the measured particle size of Tong Xin Yuan nano extract?
Measured by an independent laboratory using Dynamic Light Scattering under ISO 22412:2017: hydrodynamic diameter 122.73 nm, main intensity peak 96.67 nm (94.91% of the distribution), a secondary peak at 1.15 nm (5.09%), polydispersity index 22.0%. Test report PDF.
How does nano extraction differ from traditional grinding?
Same raw material, different process. Tong Xin Yuan nano extract measured 122.73 nm; traditionally milled particles generally sit between 100,000 and 500,000 nm — three to four orders of magnitude coarser. Finer particles mean more total surface area per unit weight. See the comparison.
Is the test report a certification?
No. It is a measurement report. The report states the sample was supplied for results only with no compliance limits — the laboratory measured and reported the values without assessing them against a pass/fail standard. We would rather say that than describe it loosely as "certified".
Does nano extraction absorb better?
Physically, finer particles have more surface area and generally dissolve and release faster, which is a reasonable inference. But what we had tested was particle size, not absorption in the body, so we report the measured size rather than presenting an absorption figure as proven.
Nano costs more per gram. Is it worth it?
Judge it across a full course rather than per gram. Nano costs more per gram but less is used per serving, so the total is not necessarily higher. Tell us the quantity you have in mind and we will work the comparison out.
