文献上报导的测定石墨中微量硼的光谱分析方法主要有下列几种:加顿(Garton)和中岛笃之助分别采用在高温下压制成球丸和棒形的样品进行直流电弧激发;斯卡尔史卡(Skal-ska)将样品与氢氧化钙混合,以碳酸锂作载体,在高温下灰化,然后在交流电弧中激发;费尔德曼(Feldman)创直接将样品装入石墨电极中,在含76%氩和24%氧的混合气体中进行直流电弧激发。戈莱布(Goleb)曾对石墨中硼、铍等27个元素进行过光谱测定。他用1.8%的氟化钠作 The following methods have been reported in the literature for the determination of trace boron in graphite: Garton and Nakashima Takeda respectively use DC arc excitation with balls and rods pressed at high temperatures; Skal-ska mixes the sample with calcium hydroxide, uses lithium carbonate as a support, ashes at elevated temperatures, and is then excited in an AC arc; Feldman inserts the sample directly into the graphite electrode DC arc excitation was performed in a mixed gas containing 76% of argon and 24% of oxygen. Goleb has performed spectroscopic measurements of 27 elements such as boron and beryllium in graphite. He uses 1.8% sodium fluoride
