摘要
目的建立不同厂家和品牌油漆稀释剂的鉴别方法。方法利用超快速气相色谱-电子鼻分析(E-Nose)技术对37种油漆稀释剂样本进行分析,采用主成分分析(principal component analysis,PCA)方法进行数据处理并建立样本识别模型。结果通过超快速气相色谱-电子鼻分析技术,可实现不同厂家和品牌油漆稀释剂的鉴别。结论为火灾现场油漆稀释剂鉴别提供了一种有效的分析手段。
Objective Establishing a method to identify different brands of paint thinner. Methods Thirty-seven samples of paint thinner were analyzed through ngerprinting by ultra-fast GC coupling electronic nose (E-nose), with the resultant data being processed by PCA (principal component analysis) statistical analysis and one recognition model thereby being brought forth. Results Ultra-fast GC coupling E-nose can identify paint thinners produced from different factories. Conclusions An effective method has been established for tracing the source of paint thinner in re site.
