Ensure SVOCs Analysis Quality with MAE microwave-assisted extraction
deliver reliable data
on any environmental matrix in organic pollutants determination
Whatever your environmental sample is, PAHs, PCBs, Pesticides, Phenols, Phthalates, EOM, Dioxins or Furans, the ETHOS X microwave extraction system equipped with fastEX-24 rotor and disposable glass vials provides reliable data for SVOCs analysis.
Why does microwave assisted extraction produce more accurate results?
The reflux action that occurs during microwave heating brings the sample in contact with fresh solvent throughout the extraction process. The homogeneity of the microwave field and the precision of the temperature control are also key elements in microwave extraction.
Excellent performance and reliable data for many analytes
Microwave Assisted Solvent Extraction can be used to replace the typical applications of Soxhlet, sonication, boiling, wrist-shaker. Performance and precision can be achieved for the following analytes:
Dioxin is one of the most toxic chemicals known, a serious public health threat. Due to the persistent nature of that compounds, the sample preparation and analysis is challenging for many extraction techniques. Many solutions are available: microwave extraction can overcome the memory effect in dioxins extraction with ETHOS X microwave extraction system powered by fastEX-24 rotor.
Pesticides are extensively used in modern agriculture, which could lead to serious health consequences. Microwave assisted solvent extraction is a well-established sample preparation technique applied in several official methods. Milestone’s ETHOS X equipped with fastEX-24 rotor was used in this study to prove its efficacy in the extraction of pesticides from environmental matrices.
Polychlorinated biphenyls (PCBs) are a group of organic pollutants consisting of 209 congeners having biphenyl as the core structural unit and a variable number of chlorine substituents. Read the guideline for the extraction of the priority polychlorinated biphenyls from both standard reference materials and spiked materials using the official method EPA 3546. The efficiency of MASE is compared with Soxhlet extraction.
Phthalates are released in the environment during the dismantling of electronic waste. As they are dangerous molecules for the human health, their analysis in environmental samples is of important value. Microwave assisted solvent extraction is a well-established sample preparation technique applied in several official methods. Since phthalates can be released in the sample from laboratory plastics, the use of proper laboratory equipment is fundamental.
Polycyclic aromatic hydrocarbons (PAHs) are toxic molecules for the human health. Microwave assisted solvent extraction (MASE) is a well-established sample preparation technique for the extraction of the priority PAHs from both standard reference materials and spiked materials using the official HJ 765-2015 method. This extraction technique can also be applied to different solid matrices such as soils and sediments.
Characterization of organic matter in the potential source rocks has always been of interest for petroleum geochemists and exploration teams in the oil and gas industries.
Thanks to the selective heating of materials, MASE is a reliable and efficient alternative to ultrasonic methods, enabling extractions with reduced solvent volume and time.

OVERCOME MEMORY EFFECT IN
DIOXIN EXTRACTION ON ENVIRONMENTAL MATRICES
is one of
the largest service laboratories in
Europe and the largest laboratory
service provider for clinics, hospitals
and the environmental industry. They have 19,000
employees and perform around
500,000,000 analyses per year.
The environmental department of
SYNLAB Linköping is focused on the
determination of organic pollutants
in different matrices, such as Dioxins
and Furans, PAH’s and PCB’s. The
main issue with their technique is
related to memory effect/ carryover
in the extraction cells. It requires long
and tedious cleaning procedures of
the extraction vessels.
“The results demonstrate the efficiency of the ETHOS X as sample preparation method for the determination of dioxins. ETHOS X provides extracts with significant lower time compared to all the other extraction techniques, avoiding any memory effect”
The stability of the
dioxins requires long and tedious cleaning procedures of
the extraction vessels. Moreover,
solvent leakage and high maintenance costs are a common challenge.
Conventional extraction systems usually do not allow to achieve the high throughput requested by daily assignments.
The fastEX24 rotor is specifically designed to overcome the
memory effect and the challenge related to the cleaning steps by using disposable
glass vials as reaction vessels, which are placed into the
pressure reactor. This approach leads to ensure great analytical blanks and completely avoid carryover between
runs. This results in increasing throughput and lowering
