dioxinIn the post “3 Facts You Need to Know About Magnetic Sector Mass Spectrometers” three unique facts about magnetic sector mass spectrometers were introduced and explained. In this post we will talk about three more facts that you need to know about magnetic sector mass spectrometers when used for dioxin analysis.

Thermo Scientific’s magnetic sector solution for dioxin analysis – the Thermo Scientific™ DFS™ Magnetic Sector GC-HRMS – is a double-focusing magnetic sector. For decades, it has been proving its proficiency in the field of dioxin analysis and has become the established analysis technique used by dioxin laboratories around the world. Together with technical improvements, this solution allows the routine detection of low femtogram amounts of highly-toxic compounds. 2378-TCDD developments in software tools for instrument control, as well as data evaluation, have led to strong improvements contributing to ease-of-use and productivity with this analytical technology.

Worldwide Compliance for Dioxin Analysis

Dioxins and other persistent organic pollutants (POPS) are everywhere, from the environment to our food. Laboratories need to analyze samples to find dioxins and POPs and guarantee their results are compliant with the regulations and controls for food and environmental safety.

Regulations are essential to ensure that dioxin levels in food and the environment don’t affect our health. For dioxins and dioxin-like compounds, regulations define the maximum levels of acceptance and official methods define the technology needed to measure them.

The most European, US and Japanese official methods, magnetic sector mass spectrometry is the suggested and recommended technique for the quantitative determination of dioxin levels. For labs, magnetic sector technology is the solution to achieve worldwide compliance.

In the table below, you can see a summary of some of the most important methods.

Flexibility of Configuration

Dioxin quantifications can be challenging, even for the most sophisticated analytical solutions. Labs need the flexibility to have configurations that can adapt to the specific analysis.

With the with the Thermo Scientific Magnetic Sector GC-HRMS solution and the Thermo Scientific DFS Magnetic sector GC-HRMS, labs can have a unique dual GC configuration and optional multi-column installation (up to four). Not only can labs perform different analytes on the different GCs, but they can have the flexibility to choose.

Enhanced Performance for Dioxin Analysis

Throughput is essential when lab’s needs to measure a number of samples with time constraints. Also, operative costs must be taken into consideration when adding analysis capacity to a lab. Considering these important needs from labs, with the DFS Magnetic sector GC-HRMS labs can now almost double their dioxin analysis performance, by choosing the dedicated DualData XL Configuration.
