气相色谱直接测定萘乙酸

Direct Determination of Naphthylacetic Acid By Gas Chromatography

本文报道了一种以ＧＤＸ－２０２作为固定相的气相色谱直接测定萘乙酸含量的新方法，该方法快速、灵敏、准确，回收率达９９．２～１０１．８％，变异系数为０．１７％。

This paper desciribes a direct determination of naphthylacetic acid by gas chro-matographrhy with a column solided with GDX-202(80～100mesh). It is rapid, sensi-tive and accurate with the recovery of 99.2～101.8%. The variation coefficient is less than 0.17%.
