Direct injection dispersion method was for determining the content of NMHC. It was determined by GC which has double column and single hydrogen flame ionization detector. Method detection limit was 0.015 mg/m3; RSD was between 0.9%~3.2%. Standard addition recovery was between 95.4%~101.7%. The method was simple operation and could quantify accurately. The results was conform to the experimental requirements.
