柱富集分离-毛细管色谱法测定柑桔油挥发物的研究

Determination of Volatile Matter of orange oil by Capillary Gas Chromatography with Pre column Adsorption——The Study of Pre Concentration Mehtod

采用吸附富集法对柑桔油挥发物进行了测定，研究对比了５种吸附剂的性能，确定了吸附富集和洗脱的条件。用毛细管气相色谱法测定了可挥发性香气成份，经与顶空法比较，证明本法具有快速灵敏等特点。

In this paper,the volatile matter of orange oil was determined by capillary gas chromatography with pre column adsorption for pre concentration.The properties of five adsorbing agents were compared.The conditions of adsorption for concentration and elution were defined.The contrast method was used for qualitative analysis with standard sample.The volatile components of cold pressed oil of orange produced from Huang Yan were studied .The method of pre column adsorption for pre concentration is rapid and sensitive by comparision with head space method.
