    Application Note: Elemental Analysis: CHNS/O Determination ...

    Samples were homogenized by a ball mill. Table 1 shows the CHNS data of six coal samples, which were analyzed ten times consequently. The calibration was performed with 2–3 mg of BBOT (2,5-Bis (5-ter-butyl-benzoxazol-2-yl) thiophene) OEA Standard. No matrix effect was observed when changing the sample. Figure 3 shows a typical CHNS chromatogram.
