元素色谱仪是有机元素(碳、氢、氮和氧)微量分析的一种重要仪器,在有机化学、生物化学及石油、化工、医药、地质等领域内得到了日益广泛的应用。这种仪器的氦气和样品用量少,不需要经常更换吸收剂,所以受到有机元素分析工作者的普遍重视和欢迎。为了满足国内需要,我们设计了 SQ-201型元素色谱仪。经过长期运行使用,于1981年进行了鉴定,各 The elemental chromatograph is an important instrument for trace analysis of organic elements (carbon, hydrogen, nitrogen and oxygen) and has been widely used in organic chemistry, biochemistry and petroleum, chemical, pharmaceutical, geological and other fields. This instrument uses less helium and less sample, does not require frequent replacement of absorbents, and is therefore well received by organic elemental analysis workers. In order to meet the domestic needs, we designed the SQ-201 elemental chromatograph. After long-term operation, was identified in 1981, each
