A Sneak Peek – The Thermo Scientific DFS Virtual User Meeting

Team TFS
Team TFS
sneak-peakAs announced in this post, on September 1-3 the DFS Virtual User Meeting was live and attended by the Magnetic Sector GC-HRMS community and beyond.

It was a great occasion to have the community gather virtually to discuss Dioxin and Persistent organic pollutants (POPs) analysis with experts directly from commercial labs and governmental institutions.

Here is a sneak peek of the program. You can also attend this on-demand webcast.

Webinar 1 – DFS Virtual User Meeting – See the latest software features for the Thermo Scientific DFS Magnetic Sector GC-HRMS: DFS Software Package on Windows 10

The latest developments for instrument and data evaluation software on Windows 10 for the Thermo Scientific™ DFS™ Magnetic Sector GC-HRMS are presented in this webinar.

To overcome wrong locking problems, which can happen with especially challenging matrices (for example sulfuric sediments, fly ashes, squalene), the Smart Mid Mode of the Thermo Scientific™ DFS SmartTune™ Operating Software offers a solution. With the Smart MID Mode, all parameters for the calibration are determined before the analysis when no sample is present. This allows you to narrow the lock mass scan, which ensures the correct calibration by excluding potential matrix interference signals.

Watch the how-to-videos explaining how it works in the software.


In the second part, the Signal/Noise Feature (of the Thermo Scientific™ DFS TargetQuan™ 4.0 Data Evaluation Software) which allows full transparency of LOQ and LOD calculations is shown.

First, you need to define the sigma value which will be applied to the calculation. Depending on which official method labs have to follow, the value might be different. Then you can define in the quantification method the time range for each analyte which then will be automatically applied. This time range is relative to the retention time of the analyte and can be before or after the peak. The range is now displayed in the chromatogram. Here it can be reviewed and adapted to the sample in case of interferences. When the signal-to-noise range is changed, the resulting parameters are automatically recalculated in real-time. In the software, the activation of the feature is a one-click process.

Check in the how-to videos to see how this is applied in the software.


Webinar 2 – Running a Commercial ISO 17025 POPs lab during a Pandemic by David Hope (Pacific Rim Laboratories, Vancouver, Canada)

With the current situation, many new rules and precautions must be implemented in all workplaces, laboratories included. At Pacific Rim Laboratories, they implemented a new set of rules to ensure the safety of employees. David Hope explains to us in detail what measures were implemented in his lab and how they are planning to run the business in this unexpected situation.

Don’t miss the webinar to see what they are doing and how they managed to run the lab during an unprecedented situation.


Webinar 3 – Estimation of LOD and LOQ for measurements in the field of contaminants with special focus on PCDD/Fs and PCBs

Alexander Schaechtele (European Union Reference Laboratory (EURL) for Halogenated POPs in Feed and Food, Freiburg, Germany) explains in detail the Guidance document on the Estimation of LOD and LOQ for measurement in the field of Contaminants in f.... The document is available on the European Union Reference lab website and gives practical information on the different approaches for the estimation of LOD/LOQ. Download the document before you attend the webinar!
