- Polychlorinated Naphthalenes with GO-xHT
Feasibility study for the Determination of Polychlorinated Naphthalenes in Food and Feed samples with a Miura GO-HT
Selective and automated purification for the analysis of dioxins and PCBs is common nowadays. However, the use of these purification devices for the analysis of other classes of compounds are studied to lesser extent. This application note demonstrates that the automated purification device GO-xHT (Miura), is suitable to purify samples for sensitive detection of polyhlorinated naphthalenes (PCNs) in addition to dioxins, PCBs and PBDEs.

Sample vial holders with exchangeable 8/9mm vial adapters
From January 2018, GO-xHT cleanup-system will be supplied with a new type of sample vial holder. This vial holder fits with 2 types adaptors :
- Adaptor No. 8 – for sample vials with 8/425 screw thread
- Adaptor No. 9 – for sample vials with 9/425 screw thread.
The advantage of this new type is a more sustainable vial holder and a perfect leak-tight connection between your sample vial and the vial holder.

- Solvent AutoExtractor - SER158
Solvent Extractor SER 148 and Solvent AutoExtractor SER 158
The first step in sample preparation of solid and semi-solid matrices, such as animal feed, soil, sludge, seed and nuts, is extraction with an organic solvent. Common manual extraction techniques are soxhlet, or twisselman (hot soxhlet) extraction.
- Improved Carbon columns
Improved carbon column
Our colleagues from Japan have recently improved the GO-HT carbon columns in order to improve the purification performance. The newly improved carbon columns have smaller particle size than before, which results in enhanced adsorbing capacity which makes the column sets less sensitive to toluene traces present in the sample extract.
- Extraction of Dioxins and PCB in low fat containing samples - solvent exchange
Extraction of Dioxins and PCBs in low fat containing samples – solvent exchange
In order to achieve good recoveries for dioxins and PCBs in environmental (soil, ash, grass etc.) and animal feed samples (compound feed, cereals, minerals etc.) extraction with toluene, using soxhlet, PLE or alternatives, is mandatory. Quite often, for instance in the case of minerals, a polar modifier such as ethanol is added to the extraction solvent. Prior to analysis on GC-HRMS or GC-MS/MS, extracts need to be purified. (more…)
- 'breakthrough' in automated sample preparation for dioxins and PCBs for European POPs laboratories
The Next Generation of Dioxin and PCB Purification
In april 2015, DSP-Systems launched a ‘breakthrough’ in automated sample preparation for dioxins and PCBs for European POPs laboratories. Manufactured in Japan, we bring a new line of sample purification systems with new technology that makes dioxin and PCB purification processes ‘greener’, safer and faster than ever before.
