Description
The present invention relates to a kind of chemical analysis instrument.
At present, what liquid---liquid extract and separate adopted usually is the single-action extraction, and with the mode of separatory funnel, this extraction once can not satisfy separation or measure requirement, and the method that must adopt repeatedly continuous extraction is to improve extraction yield.But there is certain contradiction in this extraction, and the extract and separate number of times is many more, causes tested component loss big more.Have only the minimizing number of operations, could improve quality inspection.The continuous extraction device records two kinds according to domestic and international books and periodicals, and the liquid-liquid continuous extraction device has Pai Erjin type and little prominent mark's type, the boiling point of the suitable solvent of temperature of preceding a kind of extract, so that boiling point differs is too big, mixed solvent can not use.The time of a kind of extraction in back is oversize, needs 2～24 hours, and structural design is also undesirable, is not widely adopted.
The objective of the invention is in order to alleviate reviewer's labour intensity, the protection operator's is healthy, prevents the pollution of the environment, and improves extraction efficiency, reduces inspection cost, guarantees analysis result accurately and reliably.
Accompanying drawing is a structural representation of the present invention, and 1 is cooling tube among the figure, and 2 is extraction cell, 3 is that returnable bottle, 4 is porous nozzle, and 5 is the solvent vapour glass tube, and 6 is the solvent refluxing glass tube, 7 are anti-siphon glass tube, and 8 is chilled water unit, and 9 is the dehydrating agent container, 10 is hollow float, 11 is the outer tapping bolt that divides, and 12 is taphole, and 13 is the key inner passage, 14 is stay hook, and 15 is L type glass tube bottom.
The present invention is the analytic approach of appraising and deciding according to american agriculture chemist association, and " AOAC " method principle is removed from office newly-designed, is by tested component returnable bottle (3), and sample liquid extraction cell (2) cooling tube (1) forms. Pollute in order to prevent that organic solvent steam from escaping, cooling tube (1) and extraction cell (2), employing standard ground is connected, extraction cell is made cylindrical shape, be provided with porous nozzle (4) in the extraction cell, porous nozzle (4) is the spherical crown shape of being made by glass, its bottom surface and have a plurality of spray holes on every side, in order to prevent owing to the returnable bottle drop in temperature produces contrary suction of sample liquid that negative pressure causes, be provided with glass hollow float (10) in the shower nozzle upper pipes, extraction cell is provided with the glass tube (5) that can pass through for organic solvent vapour outward, and its top is passed the extraction locular wall and entered extraction cell and be connected with porous nozzle (4), and the bottom communicates with extraction cell bottom outer wall. Extraction cell is made two kinds of shapes, and the organic solvent return duct of Type B extraction cell outside is designed to the inverted U shape, and purpose is to produce siphonage in order to prevent after withdrawing fluid from filling with return duct. Inverted U organic solvent backflow glass tube (6), one end leads in the returnable bottle (3), the other end communicates with extraction cell bottom outer wall, and the inverted U top is connected with the glass tube (7) of anti-siphon, and the upper end of anti-siphon glass tube (7) communicates with the extraction cell external wall of upper portion again. One end of the organic solvent return duct of A type extraction cell outside leads in the returnable bottle, the other end directly communicates with the external wall of upper portion of extraction cell, extraction cell outer wall cover has chilled water unit (8), chilled water unit lower end water inlet is connected on the cold water faucet, its upper end is connected with top cooling tube (1) by sebific duct, cooling water is outside the discharge pipe of cooling tube top, to prevent the organic solvent diffusion. Organic solvent return duct lower end in the returnable bottle is expanded and partly is provided with dehydrating agent container (9), return duct lower end and dewatering container ground structure cohesion. The glass tube bottom of dewatering container bottom is L-type (15), and extraction cell is connected by the standard ground with returnable bottle. The extraction cell bottom is provided with outer minute tapping bolt (11), and the key middle part is provided with taphole (12) detected sample liquid by taphole and is located at the passage (13) of key inside discharged to the extraction cell outside. Separate when preventing that returnable bottle from moving with extraction cell, the ground junction of dewatering container and return duct is provided with stay hook (14).
Extractant fully contacts with detected sample liquid, utilization is clashed into sample with the immiscible organic solvent of water, some tested components are entered in the organic facies, another component is still stayed aqueous phase, thereby reach the purpose of separation, this extractor has multi-functional programming operations system, for keeping sample liquid and the distribution ratio of extractant under the normal temperature state, outside extraction cell, be provided with water cooling plant, can directly concentrate and the recovery organic solvent, but do not scrub continuous sample introduction after the recovery, all operation sequence only needed to finish in 38 minutes.
The present invention is widely used in national defense industry, the physico-chemical analysis of agricultural, medicine, aqueous foods and others.Have rate of recovery height, favorable reproducibility, operation is simple and easy, environmental pollution is little, divide advantages such as analysis result is accurate, reliable.
