SQT 98% Content of Spongilla Spicules
The content of Bio-silicon determined by Gelatin Coagulation Gravimetric Method:
*The international standards of content were adopted by SGS // GB/T5009.3-2016
The formula of Gelatin Coagulation Gravimetric Method:
The purity of Biological silicon calculate on the W1 mass fraction of SiO2, the numerical value in %, a calculation based on formula A.1
W1=(M1-M2)/M0×100% ….. A.1
* M1 — Sample residue and Mass of nickel crucible（g）.
M2 — Mass of nickel crucible（g）.
M0 — Mass of sample（g）
Use the arithmetic mean value Of the Parallel result, the absolute difference of two parallel results should not matter than 0.2%.
Result of SiO2 Content Test
Use the arithmetic mean value of Parallel Result
