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.

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.

PFAS – Extraction, Purification and Automatization

DSP-Systems visit PromoChrom Technologies in Canada, Richmond, BC

PromoChrom Technologies manufactures smart automated SPE systems for a.o. the extraction of PFAS in water, food and soil samples.

Automated SPE for PFAS analysis

As PromoChrom’s European partner, we will help more laboratories simplify their PFAS extractions in water, food and soil samples!  SPE-03 systems are availble now for testing your application(s).

SETAC 2019 Exhibition - November 2-7 Toronto, Canada

Our first exhibition in NA was a success. The 'next generation' sample preparation systems for POPs analysis has officially been introduced in North America! An impression of our booth:

  • Analysis of Dioxins, PCBs and other POPs without methylene chloride; and < 100ml of solvent use
  • Presentation of GO-HT technology; next generation of automated sample purification
  • Poster presentation: The latest news about automated PCB 209 analysis

DSP-Systems enters the North American market with GO-HT technology from Japan.

The first GO-HT systems have been sold to commercial and governmental laboratories

During 2018-2019,  GO-HT systems have been tested by several North American laboratories. 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

From September onwards, on-site demonstrations in North America are available. We can provide a 2-channel system (GO-2HT) with a set of columns and consumables which enables for the assessment of this next generation technology in your lab. Feel free to contact us!

During Dioxin 2019 in Kyoto, in cooperation with Miura Institute of Environmental Technology (Matsuyama, Japan) the annual GO-HT lunch seminar will be organized.

August 27th, 12:00-13:00h – Room C-1.

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.
