4.Discussion of traceability
This calibrant is certified on the basis of gravimetric preparation[3]. Thus the certified value(mass concentration of 13C-Multi-Toxin is based on the weighed amount of the starting material and is therefore traceable to the stated purity of the solid raw material. High purity material represents a practical realization of concentration units, through conversion of mass to molar quantity.
5. Confirmation of certified value by LC-MS/MS
The certified concentration of 13C-Multi-Toxin of the gravimetric prepared solution was confirmed by LC-MS/MS against an independently prepared reference batch of Multi-Toxin .
