Description
Technical field
The utility model relates to a kind of extraction column aging equipment, belongs to industrial detection, quality inspection and field of immunodetection.
Background technology
For many years, the detection of trace samplings, micro-example is the emphasis in analysis and research field always, but is again difficult point simultaneously.Along with the complexity of sample improves day by day, this detection is more challenging.In recent years, the researcher has proposed multiple solution, and wherein one of effective method is the preenrichment technology.Preenrichment can be per sample characteristics, select sorbing material targetedly, realize single-minded efficient absorption to sample, the interference that can also realize removing impurity in enriched sample has caused numerous researcher's extensive interest.The appearance of some commercialization extraction materials also makes this technology be extended to fields such as industrial detection, quality inspection and immune detection by laboratory study simultaneously, has many methods also to become national standard.
In actual sample was analyzed, most widely used was gas chromatography and liquid chromatography, and the coupling that therefore extracts preenrichment and this two quasi-instrument is the most common.Because during the gas chromatography sample introduction, sample feeding mouth temperature height is had relatively high expectations to enrichment material, the preenrichment material is that extraction column must can high temperature resistant, good stability.When avoiding the enrichment material sample introduction to greatest extent material body discharge or during the material storage other adsorbed impurity discharge and cause to detect and disturb and, must pass through the program high temperature ageing for extraction column with the gas chromatography analysis method coupling to the pollution of sample.But also lack this type of at present for the exclusive aging equipment of extraction material, make troubles for the application of this type of extraction column.
Summary of the invention
At above-mentioned problems of the prior art, the utility model provides a kind of extraction column aging equipment, this extraction column aging equipment can be good at realizing that extraction column is aging, so that with the coupling of gas chromatography instrument, avoid detecting and disturb, avoid polluting chromatographic column.
The technical scheme that its technical matters that solves the utility model adopts is as follows: a kind of extraction column aging equipment comprises column oven, heating element, temperature sensor, temperature controller, have air admission hole and venthole on the column oven, the column oven appearance has the extraction column fixed orifice, the extraction column fixed hole position is in column temperature casing top, and fixed orifice quantity is one or more.Air-flow circulating fan and heating element are installed in the column oven, and an end of heating element is connected with temperature controller by the temperature compensation lead; The other end of heating element is connected with temperature controller by temperature sensor, and temperature controller is positioned at outside the column oven, and temperature sensor is positioned at column oven, and temperature sensor is connected between the logical and heating element of temperature controller by the temperature compensation lead.
Described heating element is a heating wire, and the heating-up temperature scope of heating wire is between 50 degree-600 degree.
The temperature-control range of described temperature controller is between 50 degree-600 degree, temperature-controlled precision ± 1 degree.
Air admission hole is positioned at the latter half of column temperature casing, and venthole is positioned at the first half of column temperature casing, and wherein air admission hole is communicated with the air pressure steel cylinder, and venthole directly is communicated with ambient atmosphere.
When using the utility model, earlier extraction column is inserted in the extraction column fixed orifice.Air admission hole is connected with compressed gas cylinder, control air pressure steel cylinder is inflated in column oven, gas is heated to temperature required through heating element, the gas of heating circulates in casing evenly through circulating fan, thereby extraction column is heated, realization is discharged by venthole at last to the high temperature ageing of extraction column.Temperature sensor is connected between the logical and heating element of temperature controller by the temperature compensation lead, and temperature controller can be monitored the temperature of heating element at any time, and realizes the control to temp of heating element.
The utility model is simple in structure, can carry out high temperature ageing to extraction column with the gas chromatography coupling, effectively avoid the inconvenience that when this type of extraction column practical application, causes, avoid improving the reliability of this type of sample detection because of the extraction column reason causes the failure that trace samplings or micro-example are analyzed.
