本方法用于使用日本仪器公司（NIC）汞分析仪测定液态烃中的总汞。定量下限为0.3 ng/mL（m/v-ppb）。结果可以转换为质量ppb。附录A包含碳氢化合物中汞物种的测定程序，可用于区分元素汞、有机非离子汞和离子（无机和有机）汞物种。附录B包含使用同一制造商的不同设备测定液态烃中总汞的替代程序。

This method is for determining total mercury in liquid hydrocarbons using a Nippon Instruments Corporation (NIC) Mercury Analyzer. The lower limit of quantitation is 0.3 ng/mL (m/v-ppb). The results can be converted to mass-ppb. Appendix A contains a procedure, Determination of Mercury Species in Hydrocarbons, which can be used to differentiate between elemental mercury, organic non-ionic mercury and ionic (both inorganic and organic) mercury species. Appendix B contains an alternative procedure for total mercury in liquid hydrocarbons, using different equipment from the same manufacturer.
