有机化合物中碳氢的测定,在有机元素分析中占有极重要的地位。近来因色谱技术在燃烧产物测定中的推广应用,为碳氢测定的半自动操作开创了广阔前景。但在一般实验室,完成日常大宗工作的方法,仍然是普遍采用的燃烧——重量测定法。该法原理,系有机化合物经燃烧后,借用适当的吸收剂将燃烧而生的水和二氧化碳定量吸收,根据吸收剂重量的增加 The determination of hydrocarbon in organic compounds plays a very important role in organic elemental analysis. Recently, the wide application of the chromatographic technique in the determination of combustion products has opened up broad prospects for the semi-automatic operation of hydrocarbon determination. However, in general laboratories, the method of accomplishing daily bulk work remains the commonly used combustion-gravimetric method. The principle of the law, after the organic compounds are burned, the amount of water and carbon dioxide generated by the combustion of the appropriate absorbers to absorb quantitatively, according to the weight of the absorbent increases
