QuEChERS 清理

技术

QuEChERS(快速、简单、廉 价、有效、坚固和安全)萃取 法通常用于分析各种基质中的 农药和其他污染物。它通常包 括在盐的混合物存在下用乙腈 提取,然后离心。然后通过手 动分散固相萃取(d-SPE)净化 上清液,以去除不需要的基质 化合物。

微型SPE净化使用了取代dSPE 的小柱。它实现了可靠、高通 量的样品处理,同时减少了人 力使用和仪器维护。微型SPE 对QuEChERS提取物的净化是 在清除模式下进行的,其中不 需要的基质被微SPE小柱上的 吸附剂保留,目标化合物在快 速洗脱曲时被收集。

此外,使用PAL System 、微型 SPE小柱和工作流程也实现了 乙酸乙酯提取物的自动净化 (瑞典乙酸乙酯法,SweEt)。

 

QuEChERS提取物的微SPE净化

Walk away QuEChERS extracts clean-up

See this detailed video of the µSPE workflow for the clean-up of raw pesticides extract. The PAL µSPE Cartridge is operated in scavenger mode eluting the pesticides in a clean extract. The matrix is kept on the sorbent material. The cleaned extract can be injected without waiting time online for LC/MS or GC/MS analysis. All samples are treated on the same time axis for highest reliability.

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.

Automated Sample Preparation for pesticides using QuEChERS extraction and cleanup

The QuEChERS analysis method is a popular solid-phase extraction method used for the analysis of pesticide residues in food. However, there are analytical and logistical limitations during cleanup. The Webinar shows two workflow variations for high sample throughput in online GC/MS and LC/MS analysis.

Analysis of Highly Polar Pesticides
应用说明

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.
