Total Chlorine Analysis Method for Petroleum Products

This document is a technical report detailing the test method for determining total chlorine (TCl) in new and used petroleum products through oxidative combustion and microcoulometry, as per the standards IP 9076 and UOP 9076. It outlines the challenges associated with analyzing liquid samples of varying viscosities and chlorine content without the need for sample pretreatment. The report describes the solution involving the multi EA 5100 system, which utilizes flame sensor technology for controlled combustion and direct detection of chlorine contents. The method allows for the analysis of chlorine levels ranging from 100 ng to 100 µg, covering a wide concentration range without the necessity for sample dilution. The document also details the materials and methods used, including sample preparation, calibration, and the instrumentation setup. Results from various petroleum products are presented, demonstrating the effectiveness of the method in ensuring high-quality analysis results, operational safety, and increased sample throughput.
