高频燃烧－红外吸收法测定地质样品中的碳硫

摘要

采用高频燃烧－红外吸收法测定了地质样品中的碳、硫，对称样量、助熔剂的种类及加入次序、仪器的校正及分析时间等测定条件进行了实验，确定了最佳分析条件。该方法简单、快速，测定结果准确可靠，能够满足大批量测定地质样品的需要。%A method for the determination of carbon and sulfur in various geological samples by high frequency combustion-infrared absorption was reported in this paper .Analytical conditions , such as sample weighting amount , loading sequence ,analysis time and flux types ,were tested and discussed in order to select the optimum determination conditions.Compared with classical chemical methods ,the proposed method is simple and rapid ,the result was accu-rate and reliable ,and the process is able to meet the demand of mass geological sample determination .
