EXTRACTIONS
Extraction from Mixed Matrices

The EDGE® is an automated extraction system that’s faster than Soxhlet, more automated than QuEChERS, and simpler than other solvent extraction systems. Extract a wide range of samples and sizes at least 3 times faster than other pressurized fluid extractors. This includes filtering, cooling, and washing. The EDGE has revolutionized the extraction process for sample preparation.

PFAS

PFAS are used in the manufacturing of a variety of products because of their oil, water, temperature, chemical, and fire resistance properties. Because of their chemical stability, these “forever chemicals” are used in products from non-stick cookware, to electronic devices, to low-emission automobiles. As these items are disposed of the PFAS pollute and accumulate in soils and water supplies. Humans exposure to these persistent chemicals, can lead to immune system effects, cancers, thyroid disruption, and other ailments.

 

In the laboratory, PFAS analysis is difficult because PFAS-free componentry is essential for accurate analysis. The CEM EDGE was modified to prevent the contamination of the resultant extracts by PFAS. The cleanliness of the EDGE itself after a series of washes and the background of the S1 Q-Disc®, Q-Matrix Hydra™, and the Q-Cup® used by the EDGE were examined. It was found that the substitutions provided a PFAS-free background on the EDGE, and the Q-Discs, Q-Matrix Hydra, and Q-Cups were PFAS-free. Thus, the EDGE is an excellent choice for laboratories that would like to automate their PFAS extractions without subjecting their samples to unwanted contamination.

VOC

Soil is one of the most common matrices in which semi-volatile organic compounds (SVOCs) are present. The extraction of these compounds from soil can be a lengthy and tedious process. The EDGE® is a revolutionary simple system for the rapid extraction of SVOCs from soil that is more than six times faster than other automated techniques. The Q-Cup® technology combines the process of Pressurized Fluid Extraction (PFE) and Dispersive Solid Phase Extraction (dSPE) in a single instrument that yields a fast, simple, and efficient extract. While maintaining all properties of PFE and adhering to US EPA 3545A, the EDGE also offers the benefits of the easy-to-assemble Q-Cup sample holder. The Q-Cup, with its unique open cell concept, creates a dispersive effect and promotes rapid extraction and filtration.

Pesticides

Pesticide testing is crucial to assessing the safety of fruits and vegetables for consumption. The traditional extraction method for pesticides from produce is the QuEChERS method. This method is tedious, manual, time consuming, and wasteful. Thus, there is a need for improved methods of extraction. The EDGE®, in combination with Q-Matrix™ Hydra, a waterremoving sorbent, can be used to extract a panel of pesticides from 10 g of homogenized cucumber, tomato, and green pepper in less than 9 minutes. The recoveries of the pesticide panel were greater than 70% for each matrix tested, and these results were highly reproducible. The EDGE provides a fully automated extraction that combines both the sample and sorbent into one sample vessel, alleviating the human burden of extraction and the need for multiple sample transfers.

PAH Extractions

Polycyclic Aromatic Hydrocarbons (PAH) are a major class of organic hydrocarbons that originate from both natural and anthropogenic sources. They must be tested due to their mutagenic, carcinogenic and toxic properties. PAH extractions are done using the Soxhlet method with typically large amount of solvents and long extraction times. The CEM EDGE automated extraction system, was used to extract PAHs from different food and environmental samples. All matrices were extracted with excellent recoveries up to 90% or higher.

The EDGE uses small solvent volumes, typically 35ml, with a total extraction time of only 10 minutes.

The EDGE is an ideal choice for food and environmental laboratories with different sample types and wish to implement automation in their workflow.

Dioxins Extractions

Dioxin and PCB extractions are an important aspect of food and environmental testing and safety. They are known to bio accumulate and therefor have health implications.

Traditionally Dioxin and PCB extraction are done using the Soxhlet method with hazardous chemicals at high temperatures for hours. This method is laborious, manual, time consuming and not very safe! Low level contamination of Dioxin and PCB have to be detected, which gives a challenge to sample preparation.

The CEM EDGE automated extraction system, was used to extract Dioxins and PCB’s from different meats, fish, feed, clay, soils and waste. All matrices were extracted with excellent recoveries and RSDs in a total of only 15 minutes. The EDGE is an ideal choice for food and environmental laboratories that need to extract different samples for Dioxin and PCB analysis and whish to implement automation in their workflow.
