Abstract
The utility model relates to plant tissue test technical field, is specifically related to a kind of gas collector.This gas collector comprises vacuum bag, seal closure and aspirator, in described vacuum bag, be provided with the space for accommodating plant tissue, one end at described vacuum bag is sealed and installed with seal closure, described seal closure is provided with the sealing end communicating with vacuum bag, described aspirator is installed on seal closure, for vacuum bag is vacuumized; When the gaseous compound that uses quantitative analysis by gas chromatography plant tissue to discharge, use this gas collector can collect quickly and easily the gas sample that any plant tissue discharges, can realize the vacant volume in arbitrarily quantitative this vacuum bag, and this device remains good impermeability in sampling with in collecting gas sample process, can use single sample to realize and collect the object of measuring.
Description
Technical field
The utility model relates to plant tissue test technical field, relates in particular to a kind of gas collector for vapor-phase chromatography.
Background technology
At present, when the gaseous compound that uses quantitative analysis by gas chromatography plant tissue to discharge, need to collect in advance plant and stop the combination gas sample discharging, then will after gas sample injection gas chromatography, could measure specific compound content.
The universal method of existing collection gas sample is plant tissue to be put into the airtight vessel of glass of a fixed volume, and as shown in Figure 1, the 4 use plugs sealings of this glassware, at rubber stopper punching and insert two glass tubes 5, are communicated with hose 6 between glass tube 5.During sampling, with microsyringe, insert in hose 6 and draw certain volume gas sample for gas chromatographic analysis.
But the method that this tradition is collected gas sample has four shortcomings:
The first, while carrying out quantitative test, need drainage to measure vacant volume in vessel, complex operation, easily causes error;
The second, these vessel itself are heavy, are difficult for carrying, carry inconvenience;
The 3rd, when collecting gas sample and measure, the plant tissue effect that can not be damaged, and vacant volume in vessel is determined by tissue space, therefore when gap between mensuration tissue is less compared with compounds content large and that discharge, is difficult to collect enough compounds and analyzes mensuration;
The 4th, to some organization need, use a plurality of tissue samples for collecting gas sample, caused sample waste.
Therefore, for above deficiency, need a kind ofly can to collect quickly and easily the gas sample that any plant tissue discharges, can be arbitrarily the quantitative vacant volume in locking device, and collect by using single sample to complete the gas collector of measuring.

As shown in Figure 2, the present embodiment gas collector comprises vacuum bag 1, seal closure 2 and aspirator 3, in vacuum bag 1, be provided with the space for accommodating plant tissue, in one end of vacuum bag 1, be sealed and installed with seal closure 2, seal closure 2 is provided with the sealing end communicating with vacuum bag 1, can be to the interior quantitative input gas of vacuum bag 1 by sealing end, aspirator 3 is installed on seal closure 2, for vacuum bag 1 is vacuumized.
When the gaseous compound (as ethene) of quantitative analysis by gas chromatography plant tissue release is used in inherence, laboratory, by this gas collector, can collect quickly and easily the gas sample that any plant tissue discharges.And this gas collector remains good impermeability in sampling with in collecting gas sample process, can use single sample to realize and collect the object of measuring.
Vacuum bag 1 wherein can be the transfusion flexible bag of transparent sealing, and transfusion flexible bag is good leak tightness not only, and draws materials conveniently.
In addition, air locking that vacuum bag 1 also can other vacuum-pumpings, as diaphragm seal, sealed plastic bag, the size of vacuum bag 1 is depending on the shape of plant tissue, size and the accommodation of carrying out.
The present embodiment vacuum bag 1 is preferably used transfusion flexible bag, at the interface of transfusion flexible bag, is sealed and installed with seal closure 2.
Seal closure 2 is provided with sealing end, and sealing end guarantees not have Leakage Gas in injecting gas and sampling process.
In order to reach this object, seal closure 2 is provided with through hole 24, is sealed and installed with plug 21 on through hole 24, and through hole 24 is combined into sealing end with plug 21, can use syringe to insert plug 21, to the gas of squeezing into fixed volume in transfusion flexible bag, carries out quantitative sealed.
In order to reach, save raw-material object, seal closure 2 can directly be used the vinyl cover on transfusion flexible bag, be specially: seal closure 2 comprises lid, connecting pipe 22, glue head 23, guaranteeing under bubble-tight prerequisite, between lid and vacuum bag 1 interface for removably connecting, such as being threaded, socket, clamping etc., with for convenience detach be replaced by object.Connecting pipe 22 is located on lid, and its one end communicates with vacuum bag 1, and the other end is sealedly connected with glue head 23, to guarantee the impermeability of vacuum bag 1.In actual application, the centrifuge tube after connecting pipe 22 can be and gets through, can select 1.5ml or 2ml centrifuge tube.
Lid is provided with through hole 24, on through hole 24, sealing-plug is installed, and through hole and sealing-plug form sealing end, and certainly, connecting pipe 22 also can be used as sealing end, is sealed and installed with valve or seal on connecting pipe 22, also can be used for input and the sampling of gas.
Be worth explanation, the form of seal closure 2 is also not limited to ad hoc structure, every can and vacuum bag 1 between be the protection domain of the present embodiment for the device being tightly connected.
The present embodiment is easy to make, take transfusion flexible bag as example explanation: the head of clip transfusion flexible bag, choose 1.5ml or 2ml centrifuge tube, and after centrifuge tube is got through, its one end is communicated with transfusion flexible bag through vinyl cover, and the other end, by 23 sealings of glue head, can complete making.Before use, transfusion flexible bag can be squeezed into gas sealing and be placed on built for in-water survey and whether leak gas.Correspondingly, when collecting gas sample, be further to guarantee impermeability, can spread glycerine at sealing end, with clip, clip and insert in water.
