Abstract
The utility model relates to a radioactivity chemical purity detection layer analyses jar, this chromatography cylinder include cylinder form cylinder body and rather than the cylinder cap that matches, the cylinder cap center department chromatography paper that is equipped with cuboid form put in mouthful. Cylinder body and cylinder cap be plumbous glass material. Compared with the prior art, the utility model has the advantages of, having shielded the ray source of sample application sample, having reduced the dosage of accepting in the quality testing personnel working process, convenient to use reduces the error.
Description
Technical field
The utility model is related to a kind of chromatography cylinder, more particularly, to a kind of new radio-chemical purity detection chromatography
Cylinder.
Background technology
Existing chromatography cylinder is to include cylindrical or square glass jar main body, and main body is provided with a lid, the inwall of the lid
There is a glass crotch at center, is to hang detection chromatographic paper to be used.It, with frosted mouth break-in, is to prevent that bottle with bottle cap is
The movement of lid, while play sealing function.
This chromatography cylinder has many inconvenience for radiopharmacy enterprise is specialized in.
1st, the various rays of electromagnetic radiation cannot be kept out.This is direct ray source for quality testing personnel.
Because paper chromatography chromatography requires the up height of testing staff's moment close-ups sample, and the kind speed uplink having compared with
Slowly, the time is typically longer.By taking 99mTc-MDP (mainly launching gamma-rays, primary photon energy 140KeV during decay) as an example
Morning 5：00 always finished product be about 40mCi/ml, point sample amount is about 2l-5l, and activity is about 80-200Ci.One kind is thus, more
Individual to concentrate in together, the radioactive dosage of acceptance is also very big.(explanation：Chromatography cylinder is placed on behind lead glass, has shielding well
Effect.But observation must closely near chromatography cylinder.)
2nd, the glass crotch on lid cannot firm chromatographic paper.Metal slice one is needed to hang on crotch, a connection
Chromatographic paper, because in chromatography process, it is desirable to which chromatographic paper is as far as possible perpendicular to chromatography cylinder.So chromatographic paper must exact length,
Can not bend can not be too short.Expansion process can not touch glass cover.And the chromatographic paper fragility having, such as iTLC-SG/iTLC-SA etc.,
Slightly bending will cause to damage to chromatographic paper.Affect test true value.
3rd, the refraction due to glass to light, causing visually cannot the up height of accurate observation chromatographic paper.Experimenter Jing
Often error in judgement, affects test true value.
The content of the invention
The purpose of this utility model is exactly to provide a kind of safety, use to overcome the defect of above-mentioned prior art presence
Convenient radio-chemical purity detection chromatography cylinder.
The purpose of this utility model can be achieved through the following technical solutions：A kind of radio-chemical purity detection chromatography
Cylinder, the chromatography cylinder include cylindrical shape cylinder body and matched cylinder cap, it is characterised in that described cylinder cap center is provided with one
The chromatographic paper dispensing port of rectangular-shape.
Described cylinder body and cylinder cap are lead glass material.
Described cylinder body oral area has a webbing, and to increase mechanical strength, and cylinder cap frosted mouth break-in, cylinder base have
One broadside, it is steady to place.
Described cylinder body total height 10cm, diameter 5cm, chromatographic paper total length are more than 11cm.
The long 15mm of chromatographic paper dispensing port on described cylinder cap, wide 1mm.
Compared with prior art, the utility model has advantages below：
1. lead glass material, shields the ray source of point sample sample, the agent received in reducing the quality inspection personnel course of work
Amount.
2. existing chromatography cylinder total height is 12cm, and the total length of cutting chromatographic paper is about 11cm.It is required that chromatographic paper launches
During sample, just 11cm is expanded to, is taken out at once.When chromatographic paper is during expansion, as chromatography cylinder is cylinder, also glass
The refraction of glass, the common problem of generally existing be cannot the height that launches of Real Time Observation sample, typically can take out too early or too late
Chromatographic paper.The operating error of quality inspection personnel brings very big impact to experimental result.Newly-designed chromatography cylinder total height is 10cm, is cut out
Cut the total length 11cm (can also suitably lengthen, but be identified with pencil at 11cm clear) of chromatographic paper.So there is a little chromatography
Paper is exposed on the outside, and when being expanded at 11cm, directly observes, is perfectly clear.Reduce operating error.
3. design on lid and stay an aperture, be that chromatographic paper is put down from lid aperture after chromatographic paper point sample.Ensure chromatographic paper
When sample is launched, slope is close to maximum, greatly reduces the Systematic Errors brought during launching.
Description of the drawings
Fig. 1 is structural representation of the present utility model.
Specific embodiment
The utility model is described in detail with specific embodiment below in conjunction with the accompanying drawings.
Embodiment 1
As shown in figure 1, a kind of radio-chemical purity detects chromatography cylinder, the chromatography cylinder include cylindrical shape cylinder body 1 and with
The cylinder cap 2 of its matching, described 2 center of cylinder cap is provided with the chromatographic paper dispensing port 3 of a rectangular-shape.
Described cylinder body 1 and cylinder cap 2 are lead glass material.
Described 1 oral area of cylinder body has a webbing 11, to increase mechanical strength, with cylinder cap frosted mouth break-in, cylinder body bottom
There is a broadside 12 in portion, steady to place.Described cylinder body total height 10cm, diameter 5cm, chromatographic paper total length are more than 11cm.
So there is a little chromatographic paper to be exposed on the outside, when being expanded at 11cm, directly observe, be perfectly clear.Reduce operating error.
3 long 15mm of chromatographic paper dispensing port on described cylinder cap 2, wide 1mm.After chromatographic paper point sample, chromatographic paper is from cylinder cap 2
On chromatographic paper dispensing port 3 put down.Ensure chromatographic paper when sample is launched, slope is close to maximum, greatly reduces expansion process
In the Systematic Errors brought.
Above-mentioned chromatography cylinder is applicable to the quality testing of paper chromatographic method used in all radiopharmacy enterprises.
It is applicable to the top coal drawing detection of our company's technetium 9 kinds of series and the top coal drawing detection of FDG.
