Abstract
The utility model discloses a gas chromatography advances kind integrative device of pretreatment dehydration. It includes syringe, filter head, drying device and holds the device, the syringe include injection syringe and the piston in the injection syringe, filter head be satisfied with on the injection mouth of injection syringe, drying device be satisfied with to be close to in the injection syringe one end of injection mouth, drying device be anhydrous sodium sulphate, the device that holds include the support and fix the top plate and lower plywood on the support the top plate on be equipped with a plurality of and can place the syringe of syringe and place the hole lower plywood on be equipped with with the syringe place the hole corresponding, can place a GC that GC advances the appearance bottle and advance the appearance bottle and place the hole. The utility model discloses a gas chromatography advances kind integrative device of pretreatment dehydration is suitable for the final step of drawing, not only dry moisture but also filtered the sample to satisfy the requirement that GC advances appearance.
Description
Technical field:
This utility model belongs to gas chromatogram field, is specifically related to a kind of gas chromatographic sample introduction pre-treatment dehydration integrated device.
Background technology:
Sample is before measuring with GC, and moisture and particulate matter in organic facies must remove, filter to be passed through and anhydrous sodium sulfate.Traditional method, needs first to transfer in a container, adds desiccant, transferred to by organic solvent in this container in a little centrifuge tube, after drying for preventing anhydrous sodium sulfate granule from entering organic facies, affects GC and measures, need again to filter, or centrifugal.This operation is the most loaded down with trivial details.
Summary of the invention:
The purpose of this utility model is to provide a kind of easy to operate, not only can be dried but also filter the gas chromatographic sample introduction pre-treatment dehydration integrated device of sample.
This utility model is practiced by the following technical programs:
Gas chromatographic sample introduction pre-treatment of the present utility model dehydration integrated device, it is characterized in that, including syringe, filtering head, drying device and apparatus for placing, described syringe includes syringe and the piston in syringe, described filtering head is satisfied with in the injection nozzle of syringe, described drying device is one end of close injection nozzle in being satisfied with syringe, described drying device is anhydrous sodium sulfate, described apparatus for placing includes support and the top plate being fixed on support and lower plywood, described top plate is provided with several syringe putting holes that can place syringe, described lower plywood is provided with corresponding with syringe putting hole, the GC sample injection bottle putting hole of GC sample injection bottle can be placed.
Preferably, described filtering head is a diameter of 13mm, and aperture is the filtering head of 0.45 μm.
Gas chromatographic sample introduction pre-treatment of the present utility model dehydration integrated device is so to use: place GC sample injection bottle at GC sample injection bottle putting hole, syringe is put in syringe putting hole, and make the liquid outlet alignment GC sample injection bottle of filtering head, extract piston out, wash out organic facies from extracting solution upper end be added to syringe with liquid-transfering gun or long glue head dropper, add upper piston, then piston is promoted, organic facies just flows in filtering head after anhydrous sodium sulfate removes moisture removal, after removing particulate matter, flow out to GC sample injection bottle from the liquid outlet of filtering head, thus obtain and not only eliminate moisture but also filtered the organic facies of particulate matter, meet sample introduction requirement.
Therefore, gas chromatographic sample introduction pre-treatment of the present utility model dehydration integrated device is suitable for the final step extracted, and has not only been dried moisture but also filtered sample, thus has met the requirement of GC sample introduction.
Accompanying drawing illustrates:
Fig. 1 is the structural representation of gas chromatographic sample introduction pre-treatment of the present utility model dehydration integrated device；
Fig. 2 is the structural representation of apparatus for placing；
Wherein 1, syringe；2, piston；3, filtering head；4, anhydrous sodium sulfate；5, support；6, top plate；7, lower plywood；8, syringe putting hole；9, GC sample injection bottle putting hole.
Detailed description of the invention:
Following example are to further illustrate rather than to restriction of the present utility model of the present utility model.
Embodiment 1:
As depicted in figs. 1 and 2, the gas chromatographic sample introduction pre-treatment dehydration integrated device of the present embodiment, including syringe, filtering head 3, drying device and apparatus for placing, described syringe includes syringe 1 and the piston in syringe 2, described filtering head is satisfied with in the injection nozzle of syringe, described drying device is one end of close injection nozzle in being satisfied with syringe, and described drying device is anhydrous sodium sulfate 4.The a diameter of 13mm of described filtering head, aperture is the filtering head of 0.45 μm.Described apparatus for placing includes support 5 and the top plate 6 being fixed on support and lower plywood 7, described top plate is provided with 3 syringe putting holes 8 that can place syringe, described lower plywood is provided with corresponding with syringe putting hole, to place GC sample injection bottle GC sample injection bottle putting hole 9.
