The water of crystallization (H 2 O) and CO 2 therein volatilize during the preparation of the glass beads 4, and the weight of the sample 1 decreases (hereinafter, the reduction of the weight of this sample is referred to as “LOI”). If this LOI is neglected, the analysis accuracy will decrease.

As in (c), since the mixture of the sample 1 and the flux 3 is heated and melted at a high temperature, not only the water of crystallization in the sample 1 but also the components in the flux 3 volatilize during the preparation of the glass beads 4. ..

An accurate bead weight B cannot be obtained unless the volatilization amount ΔF of the above is subtracted. Therefore, even if the concentration ratio C j is calculated based on the above equation (2), the accurate concentration ratio C j cannot be obtained. ..
