摘要
目的探索准确而简便地测定α-溴代肉桂醛的含量。方法利用气相色谱法,用玻璃柱以2%OV-17为固定液。结果在7·89～79·8ug/ml的浓度范围具有良好的线性关系,r=0·99998,平均回收率为:①94·93%(n=3),RSD=0·53%,39·1PPm,②95·19%(n=3)RSD=95·19%。66·6PPm。结论本法适用于成品检验及杂质检查。
Objective To find a precise.Simple and Convenient.method for concentration deteminating of α-Bromcinamic aldehyde.Methods A GC method sas chromatographed on glass columns with stationary fllid of 2%ov-17.Results The linear range was 7.89~79.80ug.ml^-1. The average recovevy 94.93% and RSD=0.17%(n=3)at 38.1ppm The average recovevy 95.19% and RSD=0.17%(n=3)at 66.6ppm.Conclusion The method can be used to dermineFinished Product and imturity.
