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;
