Description
Technical field
The utility model relates to a kind of online except the device of magnesium calcium in sample.
Background technique
Chromatography instrument is a kind of important detection means and method, be widely used in environmental protection, life science,
The industries such as quality inspection, Contamination Assessment, petrochemical industry and food safety.
In chromatography instrument, the chromatographic column components important as one are great on the influence of the result of detection, exist at present
During detecting various samples, a large amount of calcium ions and magnesium ions are contained in many samples, these ions often settle on a column,
The service life for not only greatly reducing chromatographic column, has an effect on testing result.
Summary of the invention
The technical problem to be solved by the utility model is to provide a kind of online except the device of magnesium calcium in sample.
In order to solve the above technical problems, the technical solution adopted in the utility model is:
Provided by the utility model a kind of online except the device of magnesium calcium in sample, including column jacket and inner prop, inner prop setting exists
In column jacket inner cavity, the top of inner prop is equipped with injection port, and centre is sample inner cavity, and bottom end is outlet；The outer wall lower part of column jacket is set
Regenerated liquid entrance is set, top is equipped with waste liquid outlet.
In the utility model, the material of inner prop is made of cation-exchange membrane.
The course of work of the utility model is: sample is entered the sample inner cavity of device by injection port, is flowed from top to bottom,
Regenerated liquid is entered in column jacket inner cavity by regenerated liquid entrance, is flowed from the bottom up, during two kinds of liquid flowings, the sodium of regenerated liquid
Ion is entered in sample by inner prop, and the calcium ions and magnesium ions in sample are entered by inner prop becomes waste liquid in regenerated liquid, waste liquid is by giving up
Liquid outlet excludes.
Preferably, in order to increase the ion exchange frequency of sample and regenerated liquid, the post jamb of inner prop is set as warp architecture.It is curved
Bent structure can increase the wave amplitude of flowing time and flowing of the sample in inner prop.Further, the post jamb upper end of inner prop and
The bending degree of lower end is greater than the bending degree of middle section.Waste liquid goes out on the separation and outer wall of inner prop post jamb top and bottom
Mouth, the site of regenerated liquid entrance are corresponding.
Preferably, it is equipped with several baffles on the sample internal chamber wall of inner prop, baffle is set, including can also increasing sample
The wave amplitude of flowing time and flowing in column improves the power and frequency of ion exchange.
The beneficial effects of the utility model are:
The utility model utilizes the ion exchange of amberplex, devises a set of on-line sample demagging calcium device,
For removing magnesium calcium and heavy metal cation in test sample, Mg in the inner cavity of inner prop2+,Ca2+And micro heavy metal ion with
Na in column jacket inner cavity+It swaps, to remove Mg in sample2+,Ca2+And micro heavy metal ion.Avoid magnesium calcium precipitate pair
The influence of chromatographic column effectively extends chromatography column life.
