Description
Technical Field
The invention relates to a special leacheate self-exhausting and liquid supplying device for an ion chromatograph.
Background
Ion chromatography is one of high performance liquid chromatography, also called High Performance Ion Chromatography (HPIC) or modern ion chromatography, which is different from traditional ion exchange chromatography column chromatography mainly in that resin has high crosslinking degree and low exchange capacity, sample introduction volume is small, and a plunger pump is used for conveying leacheate to perform online automatic continuous conductivity detection on the leacheate. Ion chromatographic separation is based on competition between the eluated and sample ions for the effective exchange capacity of the resin, and in order to obtain effective competition, it is often necessary to add an eluent additive to improve ion selectivity. Ion chromatographs are instruments that use modern ion chromatography to detect environmental samples, and are commonly used to detect anions and cations in samples including surface water, drinking water, rain water, domestic and industrial wastewater, acid sediments, and atmospheric particulates.
At present, the leacheate commonly used by the ion chromatograph is generally a low-concentration acid-base solution or an organic solvent, so that certain requirements are imposed on the material of the leacheate storage device, and a high-molecular polymer material bottle, such as a clean and non-dissolving leacheate storage bottle made of polypropylene, polyethylene, polytetrafluoroethylene, adaptive glass and the like, is usually adopted; the liquid storage bottle is divided into a rigid or flexible bottle body and a bottle body with or without a bottle cap; some bottle lids have the leakproofness themselves, and some bottle lids themselves have the switching mouth, can connect necessary leacheate protection part outward, like gas wash bottle, nitrogen gas steel bottle, air filtration purifier etc.. When the liquid storage bottle is a rigid bottle, the bottle mouth is placed upwards, and after the bottle body is filled with the leacheate, the bottle body is not full, so that a certain air cavity can be reserved at the inner top of the bottle body, therefore, in order to ensure that the air at the top of the bottle body is not introduced into an instrument, a liquid guide pipe is generally inserted into the bottom of the bottle, and the leacheate is introduced into an ion chromatograph; when the stock solution bottle is flexible bag, flexible bag sack can be placed at will, because the internal a large amount of gases that can have of bag, generally can exhaust the stock solution bottle before the stock solution.
If the ion chromatograph uses the non-degassed eluent, the detection and analysis work can be negatively influenced, and the analysis and detection work can be seriously interrupted. The main effects are as follows: when the dissolved gas in the solution is separated out in a trace amount, the detection noise and drift can be influenced, so that the detection sensitivity is reduced, and the detection precision is influenced; when the dissolved gas in the solution is seriously separated, the chromatographic pump cannot work normally, so that the detection and analysis work cannot be effectively carried out. Therefore, when using, usually the deionized water or ultrapure water for preparing the rinse solution is pre-degassed, and the common degassing method is: cooling after boiling, ultrasonic oscillation degassing for a certain time, vacuum filtration or vacuum degassing in other modes or online negative pressure membrane tube degassing and the like (higher cost); the pressure method can also be adopted to avoid the separation of bubbles, namely, nitrogen with certain pressure is instantly introduced into the leacheate liquid storage bottle which can be sealed (generally connected with a nitrogen steel bottle and a pressure gauge), and the possibility of the separation of bubbles is eliminated by pressurizing the leacheate.
In addition, if in the using process, a part of the leacheate absorbs interfering water-soluble gases in the environment such as carbon dioxide and water in the air, the leacheate is deteriorated, so that the detection sensitivity and the detection accuracy are seriously affected, and the analysis and detection work cannot be effectively developed. The following effects are mainly achieved: when water-soluble gases (such as carbon dioxide and water vapor) in the air are absorbed, the concentration of the leacheate is gradually changed, effective qualitative determination cannot be achieved, and analysis work cannot be normally carried out; when hydrogen chloride, hydrogen fluoride and sulfuric acid mist in the ambient air are absorbed for waiting for ion interferents, the background of analysis and detection is increased, and the detection sensitivity and accuracy of detection are seriously influenced.
In order to avoid the phenomenon, the leacheate is filled at one time, and meanwhile, a certain air purification device, such as a solid absorption tube (common granular soda lime and the like) and a high-concentration leacheate absorption bottle, is connected to the top of the leacheate bottle, so that the air entering the leacheate bottle does not contain gas components which interfere with detection and analysis work when the leacheate is consumed and reduced; and an inert gas pressurization and flushing mode is adopted to avoid interference gas from entering a leacheate bottle, and the main realization mode is to immediately introduce nitrogen with certain pressure (generally connected with a nitrogen steel bottle and a pressure gauge) into a leacheate liquid storage bottle which can be sealed, and fill the space vacated by the consumed leacheate with high-purity nitrogen.
Therefore, when the liquid storage bottle is made of rigid materials, the liquid guide pipe needs to be inserted into the bottom of the bottle for liquid guide, and the liquid storage bottle cannot be toppled over; when the liquid storage bottle is made of flexible materials, the liquid storage bottle needs to be exhausted in advance; if the leacheate is mixed with other gases due to improper drainage of the catheter or incomplete exhaust, the leacheate can deteriorate, so that the detection sensitivity and accuracy are affected, and the detection work cannot be effectively carried out. At present, in order to avoid the phenomenon, an air purification device and a degassing device can be adopted for solving the problem, but the air purification device and the degassing device are complicated in structure, high in manufacturing cost and not beneficial to popularization; it is also very inconvenient to carry.
