Definitions
- the present disclosure generally relates to the field of analytical chemistry including methods and devices for streamline extraction, clean-up, and enrichment of target analytes from solid and semi-solid samples.
- Pressurized liquid extraction or accelerated solvent extraction is a technique for extracting target analytes from solid and semisolid samples with liquid solvents.
- Pressurized liquid extraction utilizes increased temperature and pressure with common solvents to increase the efficiency of the extraction process.
- Pressurized liquid extraction can be used to replace more conventional Soxhlet, sonication, boiling, wrist-shaker, and other extraction methods.
- pressurized liquid systems are currently offered by the Thermo Fisher Scientific including the ASETM 350 Accelerated Solvent Extractor and the EXTREVA ASETM Accelerated Solvent Extractor.
- Pressurized liquid extraction methods performed by the ASETM extractors are accepted solid liquid extraction (SLE) methods useful for extraction of many types of analytes.
- SLE solid liquid extraction
- One such method is described in U.S. Pat. No. 5,843,311 (“the '311 patent”) and in EPA Method 3545.
- An automated system for performing a pressurized liquid extraction method is described in U.S. Pat. No. 5,785,856 (“the '856 patent”).
- An apparatus for parallel pressurized liquid extraction is described in U.S. Pat. No. 11,123,655 (“the ‘655 patent”).
- the sample is generally first ground and/or mixed with a dispersing agent.
- a weighed portion is placed in an extraction cell made of stainless steel or other materials, which is then heated to a predetermined temperature.
- a conventional static valve is opened and solvent is pumped into the extraction cell until a target pressure is reached.
- a second static valve is opened to allow the solvent with the extracted sample to flow into a collection vial.
- a method of extracting a sample can include adding a sample to a disruption and dispersion (2D) vessel, the sample being solid or semi-solid; adding a collision object and a reagent to a sample in the 2D vessel; agitating the sample, collision object, and reagent in the extraction vessel to (a) break up larger material in the sample to increase available surface area for extraction and (b) mix the reagent with the sample to disperse the sample; and performing a fluidic extraction of the sample to isolate compounds of interest in a liquid phase separate from the sample matrix material.
- 2D disruption and dispersion
- performing the fluidic extraction can include supplying an extraction solvent at elevated pressure, elevated temperature, or a combination thereof.
- the method can further include removing excess water from the sample.
- removing excess water from the sample can include centrifuging the 2D vessel.
- the method further includes adding the 2D vessel to a sample extraction vessel.
- the method can further include adding a cleaning vessel to a sample extraction vessel in series with the 2D vessel.
- the cleaning vessel can include one or more reagents for drying, defatting, or discoloration.
- the cleaning vessel can include one or more analyte trapping reagent.
- the method can further include an acetone wash to remove water from the sample where the analyte trapping reagent binds at least a portion of the compounds of interest prior to performing the fluidic extraction.
- the method can further include concentrating the extracted compounds.
- the method can further include analyzing the extracted compounds to identify and/or quantify the compounds of interest.
- an extraction apparatus can include a disruption and dispersion (2D) vessel for containing a solid or semi-solid sample, one or more types of collision objects, and one or more reagents; a cleaning vessel containing one or more cleaning reagent; and a sample extraction vessel configured to hold the 2D vessel and at least one cleaning vessel in series.
- 2D disruption and dispersion
- the 2D vessel can include titanium, stainless steel, aluminum, cellulose, polymeric material, or any combination thereof
- the cleaning vessel can include cellulose, stainless steel, aluminum, titanium, polymeric material, or any combination thereof.
- the cleaning vessel can contain one or more reagents for drying, defatting, or discoloration.
- the cleaning vessel can contain one or more analyte trapping reagents.
- the sample extraction vessel can include titanium, stainless steel, aluminum, polymeric material, or any combination thereof.
- the 2D vessel can be disposable.
- the cleaning vessel can be disposable.
- the sample extraction vessel can be disposable.
- a disposable extraction vessel can include a bottom cap comprised of titanium, stainless steel, aluminum, cellulose, polymeric substances, or combinations thereof; a cell body comprised of cellulose, polymeric substances, titanium, stainless steel, aluminum, or combinations thereof; and a top cap comprised of cellulose, stainless steel, aluminum, or combinations thereof, wherein the disposable extraction vessel is configured to withstand pressures of between about 100 psi and about 2000 psi.
- FIGs. 1 through 4 illustrate exemplary sample extraction vessel, an exemplary disruption and dispersion (2D) vessel, and an exemplary cleaning vessel, in accordance with various embodiments.
- FIGs. 5 through 8 illustrate exemplary methods of sample extraction, in accordance with various embodiments.
- a “system” sets forth a set of components, real or abstract, comprising a whole where each component interacts with or is related to at least one other component within the whole.
- Samples containing significant amounts of water can present problems for pressurized solvent extraction techniques.
- the water can be co-extracted with the sample into the solvent. This can result in an extracted sample having a different solution composition than intended, specifically containing more water than expected. This can interfere with techniques, such as evaporation, used to concentrate the sample. Additionally, in some cases, the co-extraction of the water can even be damaging to the analytical instruments, such as by damaging a chromatographic column through sudden shifts in solvent composition when a sample plug containing a high percentage of water is applied to a column. In other cases, the water may be immiscible in the solvent and result in two distinct phases, an aqueous phase and a solvent phase. This could result in the sample compounds partitioning between the phases and interfere with quantification of the compounds. As such, dewatering the sample before solvent extraction can improve the pressurized solvent extraction process.
- Preparing the samples for analysis can include disruption, dispersion, drying, defatting, and discoloration, which is referred to a 5D process.
- Disruption refers to the mechanical or chemical breakdown of sample matrices to enhance the release of target analytes. This process is vital for improving the efficiency of extraction and ensuring comprehensive analysis.
- Dispersion denotes the mechanical process of ensuring the sample is homogeneous to enhance extraction efficiency. This may be achieved by introducing reagents or dispersing agents that prevent sample particles from clogging or forming agglomerations.
- Drying refers to the removal of moisture from samples to facilitate subsequent analytical processes. This step is crucial for preventing clogging of fluidic lines and avoiding detrimental effects on analytical instrument performance. In the case of EXTREVA Accelerated Solvent Extractor, improper drying can interfere with the level sensing mechanism, leading to inaccurate results.
- Defatting involves the extraction of lipids from samples to prevent interference with target analytes. This process is critical when dealing with tissue, biosolids, and other matrices where fat not only limits extraction but can cause ionization suppression and faster damage to components of the analytical instrument.
- Discoloration pertains to the process of removing compounds, such as pigments, that generate color in the sample. This step is essential for ensuring that the sample does not retain any color that could interfere with subsequent analytical processes or the performance of the analytical instrument. Depending on the sample and the target analytes, one or more of these steps can be omitted.
