Overview

Benefits

Wide range of extraction applications

POPs from soil, sludge, sediments, air sampling cartridges (PUF, XAD), residues and contaminants from food and feed samples
Food contact materials from packaging and food
Additives, ingredients and contaminants in plastics, paper and textiles
Fat and fatty acid in food, active compounds in natural products and pharmaceutical agents in drugs

Fast and fail-safe

Shortened time to analysis as benefit of simultaneous extraction and evaporation
Direct evaporation without manual transfer of the extracts thanks to compatible glassware
Increased process safety thanks to an automated extraction cell sealing mechanism

Low running costs

Cost savings for solvents by up to 70 % compared to extractions using classical glassware
Low operator costs as laborious transfer of extracts from extraction to concentration is obsolete
Avoid costly consumables compared to other similar PSE systems

Expert Advice

Why does high pressure increase the extraction efficiency?

Read more about Why does high pressure increase the extraction efficiency?

The combination of elevated temperature and pressure results in faster extraction compared to other extraction technologies. This is the result of an improved mass transfer because of higher analyte solubility and enhanced penetration. An increase from normal pressure pn to p₂ is thereby necessary to keep the sample in the liquid state at T₂.

What is the benefit of a parallel extraction/evaporation approach?

Read more about What is the benefit of a parallel extraction/evaporation approach?

Concerted parallel extraction/parallel evaporation as opposed to a sequential approach increases the sample throughput and reduces the time to analysis significantly. An incoming batch of six samples is ready for the analysis after 115 minutes.

What is so convenient about the SpeedExtractor’s sealing system?

BUCHI’s unique extraction cell design is absolutely fail-safe, reliable and yields reproducible results. A lift mechanism automatically closes the cells at the push of a button. Hence, covering the sample with a filter paper is sufficient to make the sample ready for extraction.

Isn't there any chance of cross-contamination for adjacent positions?

Read more about Isn't there any chance of cross-contamination for adjacent positions?

Each position has its own inlet and outlet valve as well as individual pressure sensors. Even in case of blockage of one position cross-contamination is excluded as an integrated troubleshooting wizard automatically relieves the pressure. All other positions can be finished while the faulty position is deactivated.

Is it possible to do the clean-up during extraction?

Read more about Is it possible to do the clean-up during extraction?

The unique extraction cell design of the SpeedExtractor allows for various sample loadings. It is also possible to insert cleaning agents such as Florisil, silica gel, charcoal etc. for in-cell clean-up, or to apply different filling techniques. This significantly facilitates the classical clean-up procedures subsequent to extraction.

Can I evaporate DMF and DMSO with the SyncorePlus®?

Read more about Can I evaporate DMF and DMSO with the SyncorePlus®?

Yes, with the appropriate vacuum settings. For better efficiency an insulation kit is available for the SyncorePlus® racks with 24 and 96 positions. For best results, it is recommended to use the insulation kit and the Vacuum Pump V-300 in combination with the Interface I-300/ I-300 Pro.
