保护我们的环境和自然资源至关重要。水是我 们最珍贵的食物，也是我们控制最彻底的食 物。无论是饮用水、地表水还是废水，PAL System都为大样本系列的自动化分析提供了工具 和工作流程，甚至可以从水流中连续的 在线采 样。
控制水质的一种常见技术是固相微萃取 （SPME）。使用SPME Arrow可以分析最 低水平的污染物。实例包括土臭素和2-甲 基异莰醇，以及多环芳烃（PAHs）或杀 虫剂。
类似的SPME应用也用于饮料、啤酒酿造 或各种烈酒的质量控制。此外，经典的静 态顶部空间（HS）或动态顶空也可用于常 规水分析。
水、土壤或沉积物中的环境污染 物，如个人护理产品（PCPs）、杀
虫剂或激素，使用QuEChERS提 取，uSPE净化（uSPE）或SPME Arrow技术。

To support the scientific community and advance PFAS analysis we are proud to offer a webinar on this topic.
Key topics:
Advantages of automated and miniaturized µSPE clean-up in pesticides residues analysis
Recent developments in pesticides analysis extend the well-established methods to higher productivity and reliability while minimizing consumption and exposition to harmful chemicals. A workflow was developed that allows automatic preparation of calibration standards, automatic sample dilution, and automatic clean-up of sample extracts on one instrument, showing that miniaturized automated solutions are reducing errors, improving analytical consistency and protecting the environment in one convenient approach.

Analysis of Highly Polar Pesticides
Micro-SPE (μSPE) emerged as an automated green micromethod for sample preparation and clean-up in food safety, proteomics, forensic, environmental and analysis since more than ten years. Applications are wideranging and cover drugs, environmental contaminants, and, in particular, the extract clean-up in multiresidue pesticide analysis. The automation of the μSPE sample preparation steps led to the desired standardization of the applied sorbent materials for extract clean-up for the large variety of food commodities, an increase in sample throughput, and the welcome potential for offline and online hyphenation with GC/MS, LC/MS or even IC analysis.
