GC?MS)信号的解析提供了有效手段,但其在计算过程中一般需要将数据进行分段处理,然后只对信号的某些区间进行解析,难以实现真正意义上的高通量分析。该文结合移动窗口目标转换因子分析( MWTTFA)和非负免疫算法( NNIA),建立了一种高通量解析方法。首先,根据所有可能存在的目标组分的标准质谱信息,利用MWTTFA检验复杂信号中存在的组分,并确定目标组分的质谱信息和洗脱时间区域。以得到的质谱信息作为后续计算的输入值,利用NNIA解析得到相应的色谱信息。采用快速升温程序对17种和42种农药混合标准样品的GC?MS信号进行分析,利用所建立的方法可在10 min内得到全部组分的色谱和质谱信息。","authors":[{"authorName":"李跑","id":"bdce6a48-cf48-490a-9358-f4db20f4b667","originalAuthorName":"李跑"},{"authorName":"蔡文生","id":"c4a21ba2-bc83-479c-b431-ac5d9030113f","originalAuthorName":"蔡文生"},{"authorName":"邵学广","id":"46d0de32-7fa5-4ad9-b244-2346fca3b75b","originalAuthorName":"邵学广"}],"doi":"10.3724/SP.J.1123.2016.06046","fpage":"8","id":"0b1b727e-c6ca-46a5-9d6f-125d1b63f821","issue":"1","journal":{"abbrevTitle":"SP","coverImgSrc":"journal/img/cover/SP.jpg","id":"58","issnPpub":"1000-8713","publisherId":"SP","title":"色谱
