摘要
木文对汽水中苯甲酸含量的两种测定方法,气相色谱法和液相色谱法做了对照分析研究。两种分析方法的相对误差S_x分别为6.05×10^(-4)和3.16×10^(-4)变异系数Cv(％)分别为0.982和0.503、样品的平均回收率为98.59％和98.74％,证明高效液相色谱法优于气相色谱法。
In this paper, it is reported that the content of Benzoic acid in soft drink is determined by GC and HPLC. The rallies of relative error Sx, variable coefficient Cv (％) and average recovery are 6.05×10^(-4) and 3.16×10^(-4), 0.982 and 0.50a, 98.59％ and 98.74％ respectively. It is proved that HPLC is better than GC.
