Sample preparation is a key step in most analytical methods, generally regarded as the least green step of the entire procedure. The existing green metrics assess the greenness of sample preparation techniques through the evaluation of the whole analytical procedure: including sampling, sample preparation, and the final detection/quantitation. Such inclusion of the entire method makes assessing the sustainability of a newly developed sample preparation technique quite challenging, as many aspects not solely linked to the sample preparation step are unavoidably considered. Thus, an alternative metric that can explicitly and exclusively evaluate the sample preparation is proposed. The metric is simple; it reports the result with a clock-like diagram, displaying the greenness outcome of main sample preparation parameters and a total score. This new metric can differentiate closely related microextraction approaches in terms of sustainability. The metric is also open-source and can be used by downloading the Excel sheet provided.
样品制备是大多数分析方法中的关键步骤，通常被认为是整个过程中最不环保的步骤。现有的绿色指标通过评估整个分析过程来评估样品制备技术的绿色度：包括采样、样品制备以及最终的检测/定量。这种对整个方法的包含使得评估新开发的样品制备技术的可持续性变得极具挑战性，因为许多与样品制备步骤不直接相关的方面不可避免地被考虑在内。因此，提出了一种可以明确和专门评估样品制备的替代指标。该指标很简单；它以时钟状图表报告结果，显示主要样品制备参数和总得分的绿色度结果。该新指标可以根据可持续性区分密切相关的微萃取方法。该指标也是开源的，可以通过下载提供的 Excel 工作表来使用。
