1 前言如何对混合物样品不作任何化学处理或只需很少的化学处理即可获取各组分含量的信息,这是分析化学工作者长期以来寻求答案的一个重要课题。在这一领域化学计量学方法则有可能使分析化学工作者直接从复杂的、“不干净”的样品得出所需的化学信息。
1 Introduction How to obtain information on the content of individual components without any chemical treatment of the mixture samples or with little chemical treatment is an important topic for the analytical chemists in their quest for answers. The chemometrics approach in this area has the potential to make it easier for analytical chemists to derive the required chemical information directly from complex, “dirty” samples.
