Procedure Title: Accelerated Solvent Extractor
Instrumentation: ASE 150
Theory of Operation:
- The ASE 150 accelerated solvent extractor is a system for extracting hydrocarbon compounds from rock samples. The ASE 150 is used with organic solvents.
- The ASE 150 accelerates the traditional extraction process by using solvent at elevated temperatures & pressures. Pressure is maintained in the sample cell to maintain the heated solvent in a liquid state during the extraction. After heating, the extract is rinsed from the sample cell into a collection vessel and is ready for analysis.
- Extracts can be analyzed just like produced oils through gas chromatography, medium-pressure liquid chromatography, gas chromatography-mass spectrometry, and isotope analysis for liquids and solids.
Analytical Procedure:
Fill the solvent reservoir.
Remove obvious contaminants from the sample.
Pulverize the sample & pass through a 40-Mesh sieve.
Load the sample into a sample cell.
Install the waste bottle & the collection vessel.
Select or create a method.
Press the start button.
Verify the status on the status screen is oven ready & the LED on the start button is flashing.
Install the sample in the cell holder, close the door.
Press the start button.
