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%.
