This method is for the determination of low concentrations of sulfur in liquefied petroleum gases. The lower limit of detection ranges from 0.2 ppm sulfur in olefin-free butanes to about 20 ppm sulfur in a 100% olefin sample. The sulfur analyzed includes not only volatile compounds, but also high – boiling forms such as dissolved elemental sulfur.
