Dutco Tennant LLC offers a wide range of dedicated extraction solutions for the traditional determination of fast, along with contaminant analysis in several matrices as well as for residue. The entire range of automated extraction methods is covered by us from hot extraction, Soxhlet, and pressurized solvent extraction. Our solutions make way for the perfect integration in the workflow, which minimizes the manual steps. Here in Dutco, we have many We have different extractions like- Soxhlet Extraction, Hot Extraction, Microwave Digestion, Pressurized Solvent Extraction (PSE), Twisselman Extraction, Liquid-Liquid Extraction, Solid Phase Extraction (SPE) and Solid-Liquid Extraction (SLE).
For example, Soxhlet Extraction This method is applicable to the extraction of semi-volatile organic compounds from solids such as soils, sediments, sludges, and wastes. The Soxhlet extraction procedure ensures intimate contact of the sample matrix with the extraction solvent. Soxhlet is used in any chemical extraction.
In a similar way, we have different types of extractions for different requirements and different industries. In traditional extraction techniques, large amounts of solvents are used and require lengthy extraction periods for removing the analytes from the sample matrices. These extractions are conducted typically at very low pressure and temperature conditions. Pressurized Solvent Extraction is also renowned as accelerated solvent extraction, utilizes a high amount of pressures and temperatures for accelerating the extraction process. The higher temperature increases the extraction kinetics and at the same time, the increase in pressure keeps the solvent from boiling. This reduces the cost of solvent, reduces the wastage of solvent and operating costs.
The first step in sample preparation of solid and semi-solid matrices like soil, sludge, animal feed, and nuts are extracted with an organic solvent. Working together with Velp Scientifica, DSP-Systems among others of automated extraction systems. These automated systems use Randall (hot soxhlet alike) and Twisselman techniques which are suitable for virtually any kind of semi-solid and solid sample. Solid Phase Extraction is a sample preparation technology which uses chromatographic packing material, solid particle, usually contained in a cartridge-type device for chemically separating components of a sample. Samples are nearly always in the liquid state.
