Breaking Ground in Dioxin Analysis: DSP-Systems' Training Session with Micro Electron Optics S.R.L. and Amspec​

In a groundbreaking collaboration, DSP-Systems recently joined forces with Micro Electron Optics S.R.L. from Romania and Amspec for an exclusive training session focused on Dioxin analysis.

This innovative program, held at the state-of-the-art facilities of Amspec, aimed to equip professionals from Amspec with the knowledge to use advanced techniques like the Miura GO-EHT and the Shimadzu GC-MSMS for the selective, accurate and precise analysis of Dioxins and PCBs in Grains, Oilseeds, and Oils.
The training session kicked off with an introduction to the significance of Dioxin analysis in environmental monitoring. Experts from DSP-Systems and Micro Electron Optics S.R.L. provided valuable insights into the latest methodologies and technologies driving this field forward.

Participants had the unique opportunity to engage in hands-on training, gaining practical experience with the cutting-edge purification and detection equipment. Under the guidance of seasoned professionals, attendees delved deep into the nuances of Dioxin analysis, exploring best practices and troubleshooting techniques.

One of the highlights of the session was the live demonstrations showcasing the capabilities of the Miura GO-HT and the GC-MSMS from Shimadzu. Attendees witnessed firsthand how these advanced instruments streamline the analytical process, delivering accurate and reliable results with unparalleled efficiency.
Throughout the training, collaboration and knowledge-sharing were key themes. As the session concluded, participants left with a newfound confidence in their abilities to tackle Dioxin analysis challenges head-on. Armed with cutting-edge techniques and expertise gained from the training, they are poised to make significant contributions to environmental monitoring and regulatory compliance efforts.

The success of this collaborative training session underscores the importance of partnership and innovation in driving progress within the scientific community. DSP-Systems, Micro Electron Optics S.R.L., and Amspec remain committed to pushing the boundaries of Dioxin analysis, paving the way for a cleaner and safer future.
Stay tuned for future collaborations and training opportunities as we continue our mission to revolutionize Environmental, Food and Feed analysis and make a positive impact on the world around us.

The start of Dioxin analysis at Laboratorio Agrama with our first GO-eHT in Spain

Working with GO-EHT system at Agrama

With our GO-2eHT purification system, Centrivap heated vacuum evaporator and CILs complete custom standards solutions kit Manuel (head of R&D) is ready to implement the analysis of Dioxins and PCBs in vegetable oil. During our one week training and implementation session we were able to setup a method of analysis including GC-MSMS measurement and data processing. First results for home-made reference material and an oil PT sample were promising with Trueness between 90-110%, Intermediate Precision around 10% and detection limits around 0.16 pg TEQ/g fat for Dioxins and DL-PCBs.

New column sets for all 209 pcb congeners; current developments

Together with Miura Institute of Environmental Science, Alpha Analytical Laboratories in Mansfield,
MA, USA and Quality Testing and Inspection (QTI) in Rotterdam, The Netherlands, we are working on
further optimalisation of automated purification of samples for the analysis of all 209 PCB congeners.
The existing GO-EHT purification methods are capable methods, delivering suitable recoveries for
many PCBs such as NO-, MO- and NDL-PCBs.
From many customers, mainly laboratories working on environmental samples we have been receiving
requests for column sets which were suitable for the purification of all 209 PCB congeners

By modification of the formulation of the alumina column used for concentrating PCBs, recoveries
have substantially been improved, particularly for the high chlorinated ones. Recoveries for all PCB
congeners -even the most challenging ones such as # 209- are over 60% and well within the
requirements of e.g. EPA 1668. A full application note will be available around the summer of 2021.

Food and feed samples as well as environmental samples can now be analysed for dioxins and PCBs
according to EPA 1613 and EPA 1668 methods respectively. GO-EHT systems provides ‘green’
automated sample purification, without DCM, for the analysis of

  •  Dioxins only
  •  Dioxins and PCBs
  •  PCBs only (209 PCB)
  •  PBDEs, PCNs

The new column sets with improved alumina are available from July 2021.

GO-6EHT Automated sample purification system dioxins

Introducing: Vivace TM Duo: The All-in-one SPE Solution

  • For high throughput processing of small volume samples
  • Fast, Light & Versatile
  • Suitable for PFAS

Vivace™ Duo Solid Phase Extraction system is a dedicated workhorse for the efficient handling of large
batches of small biological, food and environmental samples. By running two positions simultaneously,
the Vivace™ Duo is twice as fast as single-channel systems on the market. It has a user-friendly touch
interface that can store up to 100 methods and apply up to 4 different methods for your sample batch.

Automated sample container rinsing is built-in to improve recovery for sticky compounds such as
PFAS. The backdraw feature allows analytes to bypass the syringe pump to eliminate contamination.

Food and feed samples as well as environmental samples were analysed for dioxins and PCBs according to EPA 1613 and EPA 1668 methods respectively. GO-HT systems provides ‘green’ automated sample purification, without DCM, for the analysis of

  • Dioxins only
  • Dioxins and PCBs
  • PCBs only (209 PCB method in development)
  • PBDEs,  PCNs

Topics will include:

  • Analysis of all 209 PCB according to EPA 1668
  • One shot GC-HRMS or GC-MS/MS analysis for PCDD/F & PCBs
  • Lowering LOQ to answer to EFSA’s opinion for lower background levels
  • New functions of GO-HT systems
  • New purification column for fatty samples (High capacity column)

Ongoing: Analysis of 209 PCBs using GO-HT sample purification

In close cooperation with Miura, we are working with priority on developing and optimising a purification method for all 209 PCBs. This application is in particular required for laboratories following EPA 1668 method. Experiments show that the GO-HT is suitable to perform according to EPA regulation. Final experiments are in progress for further optimization of the performance.

Ongoing: High capacity column set

Miura is currently in the finalization stage of developing a higher capacity column set for GO-HT with an improved capacity of up to 5 g fat content. This column set is expected to be available from around Autumn, 2019. More information will follow soon.
