分析生态尺度是评价分析方法绿色度的一种新颖的综合方法。它是基于分配罚分的分析过程的参数，不符合理想的绿色分析。这种方法比较了分析过程的不同参数和不同步骤。传统的绿色化学指标（例如，原子经济性，e因子和反应质量效率）是为有机制剂引入的，通常不适合绿色分析化学的目的。评价绿色分析方法的现有数据库指的是已知的程序和工具，不鼓励采用新的、更环保的等效方法。作为传统绿色化学指标的替代方案，分析生态标度可以是一个很好的半定量工具。(C) 2012 Elsevier Ltd.版权所有。
We propose the analytical Eco-Scale as a novel comprehensive approach to evaluating the greenness of analytical methodology. It is based on assigning penalty points to parameters of an analytical process that are not in agreement with the ideal green analysis. This approach compares different parameters and different steps of the analytical process.Traditional green chemistry metrics (e.g., Atom Economy, E-factor and Reaction Mass Efficiency), which were introduced for organic preparations, do not usually fit the purposes of green analytical chemistry. Existing databases for evaluation of green analytical methods refer to known procedures and instruments, and do not encourage new, more environmentally-friendly equivalents.As an alternative to traditional green chemistry metrics, the analytical Eco-Scale can be a good, semi-quantitative tool.
