Flushing made simple

During system cleaning the flushing solution can be fed directly to a waste vessel. The use of new collection bottles for the flushing solution is therefore unnecessary.

EcoMode

When operated in the Eco mode, the heating is automatically switched off after extraction is completed to save energy and costs.

Expert Advice

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?

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?

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?

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.

Is a method which has been optimized for ASE directly applicable to the SpeedExtractor?

Yes! Slight modifications in the STATIC time (i.e. HOLD for the SpeedExtractor) might be necessary (usually shorter for the SpeedExtractor).

I am familiar with classical Soxhlet extractions. To what extend is this knowledge applicable to pressurized solvent extraction?

Among the modern extraction technologies, PSE is the most comparable to Soxhlet. As a first attempt continue using the same solvent but elevate the temperature and pressure. Also, if you have successfully followed a particular sample pretreatment procedure for another extraction method, continue using this procedure.

Collection racks for SpeedExtractor E-914/E-916

The SpeedExtractor integrates different collection options with great flexibility depending on the application and following step after extraction. Although SpeedExtractor is delivered with a comprehensive starter kit the way of extract collection need to be considered separately guaranteeing a perfect fit to the subsequent step after extraction.
