Finding the right analytical chemistry contract lab for your needs can be a daunting task, especially when dealing with specialized techniques like Dionex Accelerated Solvent Extraction (ASE). Whether you require environmental analysis, food safety testing, or pharmaceutical development, selecting a lab with the right expertise, instrumentation, and commitment to quality is crucial for achieving accurate and reliable results. This comprehensive guide will walk you through everything you need to know about choosing and working with analytical chemistry contract labs specializing in Dionex ASE.
Understanding Dionex ASE and Its Applications
Dionex ASE, a patented extraction technique developed by Thermo Fisher Scientific, has revolutionized sample preparation in analytical chemistry. It offers significant advantages over traditional methods like Soxhlet extraction, including reduced extraction time, lower solvent consumption, and improved analyte recovery.
How Dionex ASE Works
Dionex ASE utilizes elevated temperatures and pressures to enhance the extraction process. This technique involves a few key steps:
- Sample Loading: The sample is placed in a stainless-steel extraction cell.
- Solvent Addition: An appropriate solvent, selected based on the target analytes, is added to the cell.
- Heating and Pressurization: The cell is heated and pressurized, accelerating the extraction kinetics and improving analyte solubility.
- Extraction and Filtration: The solvent, now containing the extracted analytes, is transferred to a collection vial, often passing through a filter to remove any particulate matter.

Advantages of Dionex ASE:
- Faster extraction times: Significantly reduce extraction time compared to traditional methods, often from hours to minutes.
- Reduced solvent consumption: Minimize solvent usage, leading to cost savings and environmental benefits.
- Improved analyte recovery: Enhance the extraction efficiency of a wide range of analytes, including volatile and semi-volatile compounds.
- Automation capabilities: Enable high-throughput analysis, improving laboratory efficiency and productivity.
Common Applications of Dionex ASE:
Dionex ASE finds applications across diverse industries, including:
- Environmental Analysis: Extracting organic pollutants from soil, sediment, and water samples.
- Food Safety Testing: Determining pesticide residues, veterinary drug residues, and other contaminants in food products.
- Pharmaceutical Analysis: Extracting active pharmaceutical ingredients (APIs) from drug formulations and biological matrices.
- Natural Product Research: Isolating and purifying valuable compounds from plant materials.
