摘要

尽管2004年为禁止使用持久性有机污染物作出了最大努力，但持久性有机污染物在全球范围内，包括在土壤中，仍然普遍存在。为了保护人类健康，农业和环境土壤需要仔细调查，但是准备气相色谱-质谱(GC-MS)分析的样品是耗时的，而且大多是手工完成的。在过去的几十年里，加速溶剂萃取(ASE)一直是首选的制备方法，虽然我们看到了进步，但该方法仍然是手动的。现在，新技术提供了并行样品处理、联合提取和蒸发以及自动化，从而加快了分析速度，降低了错误风险，并为人员腾出了时间。

New Technologies That Accelerate Persistent Organic Pollutant (POP) Sample Preparation

Despite best efforts in 2004 to ban their use, persistent organic pollutants (POPs) remain prevalent across the globe, including in soil. To protect human health, agricultural and environmental soil require careful investigation, but preparing samples for gas chromatography–mass spectrometry (GC–MS) analysis is time-consuming, and mostly done manually. Accelerated solvent extraction (ASE) has been the preferred preparation method for the past few decades, and while we have seen advancements, the method remains manual. Now, new technology offers parallel sample processing, combined extraction and evaporation, and automation—leading to faster analysis, reduced risk of error, and freed-up time for personnel.
