| Abstract: | A newly developed LPG residues measurement method is reported. First, residues in LPG is extracted into n-hexane. Then, the residues in n-hexane is analyzed by gas chromatography (GC). The method gives accurate results and good repeatability. It is powerful even at low concentration range where ASTM D2158-02 is not applicable. The method is easier to operate and takes less time compared with ASTM D2158-02 method. |
