Abstract
The utility model proposes a kind of anhydrous sodium sulfate pillars, plastic tube including 10mL, mineral wool and anhydrous sodium sulfate have up been sequentially filled by bottom in the plastic tube, the plastic tube upper end is opening, plastics bottom of the tube is equipped with the outlet of unicom, the mineral wool is filled to the outlet, and the quality of the anhydrous sodium sulfate is 1g, and the anhydrous sodium sulfate and mineral wool account for the one third of the plastic tube volume.The anhydrous sodium sulfate pillar of the utility model, the setting filling of mineral wool layer and anhydrous sodium sulfate layer is close, the moisture in volatile solvent can fully be removed, improve the gasification efficiency of sample, eliminate loss of the moisture to gas chromatographic column, to improve the Stability and veracity of result, working efficiency is also improved.
Description
Technical field
The utility model is related to detect instruments of inspection field more particularly to a kind of anhydrous sodium sulfate pillar.
Background technology
Iodine, hexamethylene diamine, ethylenediamine, methyl methacrylate etc. are needed organic molten by aqueous phase solvent derivative volatility
The sanitary index of agent extraction, extracting solution need that gas chromatographic detection could be used after anhydrous sodium sulfate is dehydrated.
Utility model content
The purpose of this utility model is that proposing a kind of anhydrous sodium sulfate pillar, the moisture in detection sample is rapidly removed,
Improve the accuracy of result.
The utility model proposes a kind of anhydrous sodium sulfate pillars, include the plastic tube of 10mL, by bottom in the plastic tube
It is up sequentially filled mineral wool and anhydrous sodium sulfate, the plastic tube upper end is opening, and plastics bottom of the tube is equipped with going out for unicom
Mouth pipe, the mineral wool are filled to the outlet, and the quality of the anhydrous sodium sulfate is 1g, the anhydrous sodium sulfate and glass
Glass cotton accounts for the one third of the plastic tube volume.
In the utility model one or more embodiment, the plastic tube upper port is equipped with the convex edge extended outward,
It is easy to use for being affiliated to erection plastic tube.
In the utility model one or more embodiment, the plastic tube is that internal diameter is 1cm, and height is the cylinder of 5cm
Body.
In the utility model one or more embodiment, the outlet is set at the central axes of plastics bottom of the tube.
Further include reception pipe in the utility model one or more embodiment, the reception pipe is set to the plastic tube
Lower section, and the nozzle of reception pipe covers the lower part of the outlet, the nozzle of the reception pipe is less than or equal to the plastic tube
Outer diameter, the reception pipe is for receiving scavenging solution.
The beneficial effects of the utility model：The anhydrous sodium sulfate pillar of the utility model, mineral wool layer and anhydrous sodium sulfate
The setting filling of layer is close, can fully remove the moisture in volatile solvent, improve the gasification efficiency of sample, eliminates moisture to gas
The loss of phase chromatographic column also improves working efficiency to improve the Stability and veracity of result.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Specific implementation mode
As follows in conjunction with attached drawing, application scheme is further described：
Referring to attached drawing 1, a kind of anhydrous sodium sulfate pillar includes the plastic tube 1 of 10mL, from bottom in the plastic tube 1 toward
On be sequentially filled mineral wool 3 and anhydrous sodium sulfate 2, form mineral wool layer and anhydrous sodium sulfate layer.1 upper end of the plastic tube is
It is open, the outlet 11 of unicom is equipped at 1 bottom central axes of plastic tube, the mineral wool 3 is filled to the outlet 11, glass
The setting of glass cotton 3 can prevent anhydrous sodium sulfate 2 from leaking.The quality of the anhydrous sodium sulfate 2 is 1g, the anhydrous sodium sulfate 2
The one third of 1 volume of the plastic tube is accounted for mineral wool 3.Specifically, it is 1cm that the plastic tube 1, which is internal diameter, height is 5cm
Cylinder.
Further, 1 upper port of the plastic tube is equipped with the convex edge 12 extended outward, and plastic tube 1 is set up for being affiliated to,
It is easy to use.
Further, further include reception pipe 4, the reception pipe 4 is set to below the plastic tube 1, and the nozzle of reception pipe 4
The lower part of the outlet 11 is covered, the nozzle of the reception pipe 4 is less than or equal to the outer diameter of the plastic tube 1, which uses
In reception scavenging solution.
The anhydrous sodium sulfate pillar of the present embodiment has preferable adsorption capacity to the moisture in volatile organic solvent, can
The moisture in sample is rapidly removed, the factor for sample gasification efficiency of eliminating the effects of the act.Specifically used step is：By 1 upper end of plastic tube
The convex edge 12 of mouth is erected on holder, and anhydrous slufuric acid is added from 1 upper port of plastic tube in the volatile solvent sample solution of 2-5ml
In sodium pillar, reception pipe 4 is placed under plastic tube 1, nozzle covers the lower part of the outlet 11, net using gravity sample
It is flowed out from outlet 11 after change, scavenging solution is received by reception pipe 4.
It is that above-mentioned preferred embodiment should be regarded as application scheme embodiment for example, all with application scheme thunder
Technology deduction, replacement, improvement etc. same, approximate or make based on this, are regarded as the protection domain of this patent.
