Introduction: Rapid solvent extraction technology is a kind of sample pretreatment method for rapid extraction of target components in solid or semi-solid samples. Compared with commonly used methods such as Soxhlet extraction and ultrasonic extraction, the extraction time can be greatly shortened and the extraction efficiency can be improved. The amount of extraction solvent, which significantly reduces the extraction costs of a single sample. The principle of rapid solvent extraction technology is: during the extraction process, the sample is heated and pressurized. Under high temperature conditions (temperature of 50°C~200°C), the desorption and dissolution kinetics of the analyte from the substrate are accelerated. The extraction time is greatly shortened, and the extraction time is from several minutes to twenty minutes. At the same time, since the heated solvent has a stronger dissolving power, the amount of solvent can be reduced. The solvent consumption is several milliliters to ten milliliters; under high pressure (pressure 10 MPa to 20 MPa), the boiling point of the solvent can be extracted to maintain the liquid state, thus ensuring the safety of the extraction process. The BASE-26 full-automatic rapid solvent extraction instrument produced by our company is a rapid sample pretreatment device designed for solid and semi-solid samples based on the principle of appeal. It is suitable for the existing chromatography, chromatography-mass spectrometry and other analytical instrument sample pretreatment. . The instrument is easy to operate and has a high degree of automation. The solvent, heating, pressurizing, extracting, rinsing, filtering, extracting, purging, and nitrogen blowing are all automatically controlled, and the extraction of up to 26 samples can be automatically performed each time. Each extraction cell The volume can be optionally in 5 ml, 11 ml, 22 ml, 33 ml, 66 ml, 100 ml. The entire extraction process can be unattended, any operation abnormal, automatic alarm and stop working, greatly reducing the operator's contact time with organic reagents, reducing the operator's labor intensity, improve work efficiency. It can be widely used for rapid extraction of target components from solid or semi-solid samples in soils, environments, chemicals, pharmaceuticals, electronics, agricultural products, foods, and some natural products, such as pesticides and herbicides, and polycyclic aromatic hydrocarbons in soil. And Dornyc-biphenyl; multiple pesticide residues in food, vegetables, fruits, and animal feed; active ingredients in natural products; pharmaceutical additives in health products. Technical Parameters: Integrated design of chemically inert extraction cell (patented), end caps, filter discs and seals are integrated into one design for ease of use and easy maintenance Can be placed in a fume hood for experimentation Full-cycle furnace design, temperature range: room temperature ~210°C Pressure range: 0~25MPa Extraction cell volume: 1ml, 5ml, 11ml, 22ml, 33ml, 66ml, 100ml Extraction time: <20min Extracts can be automatically filtered Extract 26 samples at a time Solvent Controller (Proportioning): According to the proportion of the mixed solvent set in advance, the mixing ratio of up to 4 solvents can be automatically completed
BASE-26 automatic fast solvent extractor is a fast sample pretreatment device designed for solid and semi-solid samples based on the principle of attraction. It is suitable for sample pretreatment of existing chromatography, chromatography-mass spectrometry and other analytical instruments.
