| Abstract: | Using dual column with flame ionization detector to determine total hydrocarbon and non-methane hy drocarbon in air. One of the column was filled with quartz sand as hydrocarbon column, and another with GOX-502 as methane column. Total hydrocarbon was qualitatively determined by methane gas standard method, and quantitated by other standardization, the method was faster and easier, precise, accurate and limit of quantitative detection were satisfactory. |
