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。

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.

Advantages of automated and miniaturized µ-SPE 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 flavors, pesticides, and biomarkers directly from complex food matrix using the automated Vacuum In-Tube Extraction (V-ITEX)
Extraction of volatile compounds is a widely used approach for analysis of foods and beverages. By the nature of gas phase sampling, the limiting factor for polar analytes are given by low vapor pressure or higher boiling points of semi-volatile compounds. These limitations can be overcome by sampling at decreased pressure levels using vacuum conditions. This has been shown in several publications using vacuum sampling techniques. In this study, a fully automated approach of Vacuum In-Tube Extraction (V-ITEX) is presented, a simple and fully automated technique using PAL system autosamplers. The application examples include flavors, fragrances, off-flavors, pesticides and biomarkers by extractions directly from the food sample matrix, such as Honey, Bee Wax, Cheese, Onions, Blood and Urine.
