SPE-DEX® 4790 Extractor System

"Needs technology update, better computer control and applications support."

Description

 

The SPE-DEX 4790® Automated Extraction System is a fully automated sample preparation system designed to rapidly process samples for trace level analysis of organic chemical contaminants from aqueous samples using EPA Methods for Solid Phase Extraction (SPE).

Analytical Laboratories are pressed to provide the best turnaround time with economy and accuracy. The Horizon Technology SPE-DEX® 4790 Extractor can help by providing rapid, reproducible extraction of semivolatile organics from liquids, getting a better-prepared sample to the chromatograph faster.

Although much progress has been made in improving the analysis step, the sample preparation step can still be improved. The Horizon Technology SPE-DEX 4790 Extractor provides a combination of factors help to speed extraction of semi-volatiles from water. The system is automated, requiring less attention and more providing a more reproducible process. The second important factor is the use of solid phase extraction (SPE) to collect and elute the analytes, reducing the extraction time and solvent usage.

The SPE-DEX® 4790 Extraction System uses Solid Phase Extraction (SPE) technology to replace the old, labor-intensive liquid-liquid extraction (LLE) technique. In addition to delivering accurate, more consistent results, SPE technology slashes both sample processing times and solvent use.

Solvent consumption is cut by up to 90% compared to traditional liquid-liquid extraction methods. Sample run times are less than 5 minutes.

Unattended operation increases the overall productivity of your lab as personnel are freed up for other projects. Plus variability between chemists' techniques is eliminated. The SPE-DEX® 4790 Extractor processes samples directly from the original sample bottle. It automatically delivers all solvents, regulates sample processing and disk drying times, rinses the sample bottle and collects the extract.


The SPE-DEX® 4790 Extraction System features:

  • Bench-top operation frees up valuable hood space
  • Modular design allows for addition of up to seven extraction stations
  • Interchangeable 47mm, 50mm, 90mm SPE disk holders
  • Handles sample volumes from 20ml to 4L
