技术领域technical field
本实用新型属于实验室器具技术领域，特别涉及一种应用于固相萃取仪的气液分离装置。The utility model belongs to the technical field of laboratory appliances, in particular to a gas-liquid separation device applied to a solid-phase extraction instrument.
背景技术Background technique
固相萃取仪是实验室的一种常用仪器，将固相萃取的各个步骤有效的集成于一个平台，由液固萃取和柱液相色谱技术相结合发展而来，主要用于样品的分离、纯化和浓缩。然而在仪器使用过程中，萃取得到的废液会集中在仪器内部的容器中。在使用真空泵营造负压提高萃取速度的情况下，当废液积蓄较多时，废液就会从固相萃取仪的抽气孔的位置沿着压力向真空泵端移动。当有机废液进入真空泵腔体中，会损坏其中的部件，极大地减少了仪器的使用寿命，且真空泵抽出的废气还需要进行净化才能排放到环境中。Solid phase extraction instrument is a commonly used instrument in the laboratory. It effectively integrates the various steps of solid phase extraction into one platform. It is developed from the combination of liquid-solid extraction and column liquid chromatography technology. It is mainly used for the separation of samples, Purified and concentrated. However, during the use of the instrument, the extracted waste liquid will be collected in the container inside the instrument. In the case of using a vacuum pump to create a negative pressure to increase the extraction speed, when the waste liquid accumulates a lot, the waste liquid will move from the position of the suction hole of the solid phase extraction instrument to the vacuum pump end along the pressure. When the organic waste liquid enters the cavity of the vacuum pump, it will damage the components and greatly reduce the service life of the instrument, and the exhaust gas drawn by the vacuum pump needs to be purified before it can be discharged into the environment.
因此需要对现有技术进行改进，延长固相萃取仪的使用寿命，减少环境污染。Therefore, it is necessary to improve the existing technology, prolong the service life of the solid phase extraction instrument, and reduce environmental pollution.

分离装置的气液分离部分，可通过洗气瓶改造而成，其中瓶体采用玻璃或者透明塑料材质，透明瓶体使用双孔塞密封，双孔塞的一个孔密封插接进气管，双孔塞的另一个孔密封插接出气管，出气管进气口处附有倒圆锥型防水盖10，出气管出气口与气体干燥检测部分紧密连接；进气管、出气管和双孔塞之间密封插接，进气管出气口接近透明瓶体底部，与底部之间的距离为透明瓶体高度的1/20-1/4，本具体实施例中优选1/10，进气管进气口与固相萃取仪连接，出气管在透明瓶体内的深度显著短于进气管，出气管进气口接近双孔塞内侧，与双孔塞内侧之间的距离为透明瓶体高度的1/20-1/5，本具体实施例中优选1/10，出气管进气口处附有倒圆锥型防水盖，防水盖覆盖出气管部分的管壁上有一个直径大小为出气管管径的1/3-1/2的排气孔11，出气管出气口与气体干燥检测部分紧密连接，气体干燥检测部分的出口与真空泵相连；气体干燥检测部分内部按气体流动方向依次装有脱脂棉、活性炭、干燥剂和指示剂；脱脂棉阻止大颗粒液滴或误入的固体，活性炭吸附各种有机试剂蒸汽或刺激性气体，干燥剂选择干硅胶或氯化钙，用以去除水分，指示剂显示系统使用状态。The gas-liquid separation part of the separation device can be transformed into a gas washing bottle. The bottle body is made of glass or transparent plastic, and the transparent bottle body is sealed with a double-hole plug. The other hole of the plug is sealed and inserted into the air outlet pipe, and an inverted conical waterproof cover 10 is attached to the air inlet of the air outlet pipe, and the air outlet of the air outlet pipe is closely connected with the gas dry detection part; Plugging, the air inlet of the air inlet pipe is close to the bottom of the transparent bottle, and the distance between the bottom and the bottom is 1/20-1/4 of the height of the transparent bottle, preferably 1/10 in this specific embodiment, the air inlet of the air inlet and the solid The phase extractor is connected, the depth of the outlet pipe in the transparent bottle is significantly shorter than the inlet pipe, and the air inlet of the outlet pipe is close to the inner side of the double-hole plug, and the distance from the inner side of the double-hole plug is 1/20-1 of the height of the transparent bottle body /5, preferably 1/10 in this specific embodiment, an inverted conical waterproof cover is attached to the inlet of the air outlet pipe, and the waterproof cover covers the wall of the air outlet pipe with a diameter that is 1/3 of the pipe diameter of the air outlet pipe -1/2 exhaust hole 11, the air outlet of the gas outlet pipe is closely connected with the gas drying detection part, and the outlet of the gas drying detection part is connected with the vacuum pump; the gas drying detection part is equipped with absorbent cotton, activated carbon and desiccant in sequence according to the gas flow direction And indicators; absorbent cotton to prevent large droplets or strayed solids, activated carbon to absorb various organic reagent vapors or irritating gases, choose dry silica gel or calcium chloride as desiccants to remove water, and indicators to display the status of the system.
使用时，将进气管进气口与固相萃取仪的抽气口紧密相连，气液体进入透明瓶体进行气液分离；但当液体处在负压状态下，蒸发速度会加快，即便有了气液分离也无法完全隔绝带有蒸汽的气体进入真空泵中，故分离后的气体进入气体干燥检测部分，可以将液滴、固体颗粒物等非气体物质完全过滤后再进入真空泵，提高仪器的萃取速率，大大延长其使用寿命，并减少环境污染，指示剂可以反映处理后的气体是否还带有蒸汽,并可以知道脱脂棉、活性炭和干燥剂的使用状态，便于及时更换脱脂棉、活性炭和干燥剂。When in use, the air inlet of the air inlet pipe is closely connected with the suction port of the solid-phase extraction instrument, and the gas and liquid enter the transparent bottle for gas-liquid separation; but when the liquid is in a negative pressure state, the evaporation speed will be accelerated, even with gas Liquid separation cannot completely isolate the gas with steam from entering the vacuum pump, so the separated gas enters the gas drying detection part, which can completely filter non-gas substances such as liquid droplets and solid particles before entering the vacuum pump to improve the extraction rate of the instrument. Greatly extend its service life and reduce environmental pollution. The indicator can reflect whether the treated gas still contains steam, and can know the use status of absorbent cotton, activated carbon and desiccant, which is convenient for timely replacement of absorbent cotton, activated carbon and desiccant.
