考察室外自然风化对原油液相色谱稳定特征峰分布的影响,提出基于溢油液相色谱稳定特征峰比值结合聚类分析和"t-检验"分析进行模拟溢油鉴别.结果表明,液相色谱稳定特征峰比值结合聚类分析可以初步推测模拟溢油样品来源,进一步采用特征峰比值和"t-检验"分析可以实现模拟溢油样与可疑原油样品的成功判别.
The effect of weathering outdoors on the distribution of HPLC characteristic peaks is examined,and a methodology using HPLC stable characteristic peak ratios combined with several statistical data correlation analysis methods is developed for oil differentiation,including clustering analysis and Student′s t-test method.The origins of simulated oil spills can be speculated preliminarily through the method using HPLC stable characteristic peaks ratios combined with clustering analysis.Further,the oil spills and suspected sources can be successfully identified via using HPLC stable characteristic peaks ratios combined with Student′s t-test method.The methodology using reverse phase HPLC stable characteristic peaks ratios combined with multi-statistical analysis is expected to be a powerful tool for the discrimination of oil spill discrimination.
