    7 Calculation

    The sulfur content of the sample is calculated according to formula (3) or formula (4):


    In the formula: X 1 — sample sulfur content, ng/mL;

    X 2 — sample sulfur content, ng/mg;

    W—Sulfur content displayed by microcoulometer, ng;

    V—Injected gas sample volume, mL;

    F—Sulfur recovery rate, %;

    P—Atmospheric pressure, Pa;

    t—sample temperature, ℃;

    M—The molar mass of the sample, g/mol;

    8317.
