Abstract:
Fluorine, chlorine, and sulfur are a concern in LPG. Pyro-hydrolytic combustion coupled with ion chromatography (CIC) is an ideal approach to eliminate the sample matrix and increase sample homogeneity. Total fluorine, chlorine, and sulfur in LPG were determined by pyro-hydrolytic combustion at 900 °C and absorbed in 50 mg/L peroxide solution. The resulting ions were separated by anion-exchange chromatography using an electrolytically generated hydroxide gradient at 0.3 mL/min and detected by suppressed conductivity. The method had good precision and sensitivities. The calibration curves were generated using incremental combustions of one standard. CIC allows an automated safe analysis of LPG samples.
