Validation of a microwave-assisted protocol for the determination of saponification number: a comparison to ISO 3657:2020

Saponification number in oils measures the amount of alkali required to convert fats into soap and it is a crucial parameter for formulation of industrial or artisanal soap. Microwave assisted solvent extraction is a well-established sample preparation technique and offers a reliable and efficient approach for its quantification. Milestone ETHOS X equipped with fastEX-24 eT rotor was used in this study to demonstrate its effectiveness in comparison with official ISO 3657:2020 method and European Pharmacopoeia.

Improved Characterization of Fatty Acids in Food

Food products are routinely analyzed to determine their composition in saturated and unsaturated fatty acids to communicate their nutritional value, monitor their quality and origin, and confirm the absence of TFAs In cooperation with Gembloux Agro-Bio-Tech, University of Liège, Belgium, a new and accurate method was developed for preparing FAMEs from a wide variety of foodstuff using a single-step microwave-assisted extraction and derivatization coupled with GC×GC analysis to identify and quantify the individual fatty acid. Results was also compared with those from two different official FAMEs preparations: AOCS Official Method Ce 2b-11 and Cruz-Hernandez et al. J AOAC Int 87(2) 2004 545.

Microwave assisted extraction of dioxins from fly ash samples

Dioxins are toxic and persistent molecules covered by the Stockholm Convention and several governments require their analysis in environmental samples. Microwave assisted solvent extraction is a well-established sample preparation technique applied in several official methods. Milestone’s ETHOS X equipped with SR-15 eT rotor and glass vial kit was used in this study to prove its efficacy in the extraction of dioxins from fly ash samples. Discover the study that represents a guideline for the extraction of dioxins and furans from standard reference materials using the official method EPA 3546.

Microwave extraction of hydrocarbons from soils samples. A comparison with iso 16703:2004

ISO 16703:2004 specifies a method for the quantitative determination of the mineral oil (hydrocarbons) content in field-moist soil samples by gas chromatography. Many environmental laboratories use this method daily. Microwave-assisted solvent extraction is a well-established sample preparation technique applied in several official methods. Milestone’s ETHOS X with fastEX-24 eT rotor was used in this study to prove its efficacy in the extraction of hydrocarbon from soil samples in comparison with the ISO method.
