摘要
以烟草为分析对象,研究离子阱质谱在植物样品分析中的应用。结果表明,GC/MS/MS通过选择特定的先驱离子,具有很高的特异性,基本排除了样品中其它物质的干扰。6种烟草生物碱相对标准偏差为0.45%～4.52%;最低检出限达到0.33μg/g。
The application of ion trap mass spectrum in the analysis of plant samples was studied taking tobacco samples as the object.GC/MS/MS has perfect specificity and eliminates the interference from other substances by selecting given precursor ions.The relative standard deviations were 0.45%～4.52%and the LOD was 0.33μg/g.
