在石油地球化学研究中,对有机氧一般采用国外进口的元素分析仪进行测定。由于条件的限制,我们引用大连第二仪表厂出品的SOM-1型脉冲加热-气相色谱仪,对有机氧测定的各种条件进行了试验。试验证明,操作简便、性能稳定、方法可靠。 1.仪器、试剂及操作 SOM-1型脉冲加热-气相色谱仪; 氩气(99.99％)、分子筛(5埃、40—60目)、石墨坩埚(采用光谱纯石墨电极车制而成);
In the research of petroleum geochemistry, the organic oxygen is usually measured by the elemental analyzer imported from abroad. Due to the limitations of the conditions, we quoted the SOM-1 pulse heating-gas chromatograph manufactured by Dalian No.2 Dashidian Factory and tested the conditions for the determination of organic oxygen. Test proved that easy to operate, stable performance, reliable method. 1.
