Description
Technical field
The utility model relates to the semi-automatic filling device of gas chromatographic column.
Background technology
Gas chromatography (GasChromatography, GC), through the development of over half a century, has become onePlanting widely used mixture method for separating and analyzing, has been that one is quite ripe, application separation very widely,The method of Analysis of Complex mixture.
The operation principle of gas-chromatography (GC): injector is by after sample drawing-in system, and carrier gas is by sample component bandPeople's chromatographic column separates, and it is detected that the rear each component of separation enters detector under carrier gas is auxiliary, passes through signalConversion, register system obtains the response signal of sample component, obtains chromatogram, finally can be by the guarantor of chromatographic peakStay time, peak height and peak area to carry out qualitative and quantitative analysis.
Gas chromatograph is by air-channel system, sampling system, column system, detection system, data handling system etc.Form, wherein chromatographic column and detector are the core components of GC, are the important of major effect GC analysisFactor.
That is to say, gas chromatographic column is one of core component of gas chromatograph. In the time of gas chromatographic analysis,The selection of chromatographic column is most important, need to consider that the character, experiment condition of component to be measured are (as column temperature, post are pressedHeight) etc.
According to the size of chromatographic column internal diameter and length, pillar is divided into packing gas chromatography post and capillary simplyPipe gas chromatographic column, and the internal diameter of pointing out packing gas chromatography post is at 2-4mm, length is l-10m; CapillaryGas-chromatography column internal diameter is at 0.2-2.5mm, length: generally at 25-100m. This classification is actually notRigorous, be the differentiation in a kind of presentation.
Packing gas chromatography post, conventionally referred to as chromatographic column, mainly contains gas-solid chromatograph chromatographic column and GLC lookTwo types, spectrum post. Gas-solid chromatograph chromatographic column adopting solid matter, as fixing phase, comprises and has adsorption activityInorganic adsorbent, porous polymer bead and surface by the solid matter of chemical bonding. GLC chromatogramIn post, filler used is stationary liquid phase, and it is by the upper stain that is coated with of the solid support of inertia and its surfaceHigh boiling point organic compound liquid film forms.
The quality of fixing phase filling quality directly affects the post effect of chromatographic column. Fill good chromatographic column for one,Conventionally theoretical cam curve should reach 2000/m. Can according to circumstances select in order to obtain best filling effectDiverse ways below, the fill method of fixing phase generally find time method, pressurization and pressurization.
The method of finding time need instrument have vavuum pump, two rubber tubes, rubber bar, iron stand, titration folder, beaker,Medicine spoon, little triangular funnel, thin metal rod (using at post two end plug mineral wools), surge tank.
The method of finding time operating procedure:
A, void column is vertically fixed on iron stand, two ends upwards clamp;
Chromatographic column has two kinds, and a kind of is that two ends are equally long, and another kind is that one is long and the other is short at two ends. Two ends oneSample long in the time filling regardless of direction, one is long and the other is short at two ends directionality, long one end connects injector,A short termination detector, dress will be connected on little triangular funnel one end of injection port before post;
B, post and funnel are nested together with the long soft rubber tube of about 10cm, attention will be overlapped tightlyer, in order to avoidWhile adding carrier, can leak;
C, mineral wool is filled in to one end of void column connection detector, the about 5cm of the degree of depth.
D, one of the silicone rubber tube that about 50cm is grown are connected on surge tank, and other end is connected on the detector of void column-end.
E, in little funnel, add a little carrier (about l-2mL), knock gently void column with rubber bar carrier is fallenEnter in column jecket, start vavuum pump, make this little carrier arrive fast mineral wool position and form effectively and block.
F, continuation add carrier in funnel, and slowly knock the diverse location of post, make carrier as far as possible closely,Substantially while filling up, carefully knock post, carrier tightens any and just adds a bit again, until cannot be tight again.
G, pull out the little funnel of injection port end, add a mineral wool, jam-pack.
If glass column will respectively put at two ends a cushion rubber, prevent from smashing when nut from falling chromatographic column.
After making marks, (recommend close plating swatch) on post, aging in dress people chromatograph box.
Pressurization is that the other end is connected with filler pond by the mineral wool of the good silanization of an end plug of chromatographic column. FirstTo fix the filler of falling people pond mutually, the other end outlet in filler pond is connected with the pressure-reducing valve of nitrogen, for commonInternal diameter is the chromatographic column of 2mm, and adjustable gas flow is 30mL/min left and right, the look of other different inner diametersSpectrum post air-flow can be done suitable adjusting, by fixing the pressure mutually in people's chromatographic column of filling in pond, uses rubber bar simultaneouslyOr wooden stick raps chromatographic column fills evenly the fixing sun of filling out mutually. After fixing filling mutually, in original connectionFill one end mineral wool of silanization beyond the Great Wall in pond, notice that this one end should be connected with chromatographic Sample Room,The other end is connected with detector as outlet, can not connect anti-.
General filling for some low boiling fixer of manual completion method. Conventionally adopt limit rim to beatWay. The filler of at every turn adding in post should not be too many.
When filling, should note 2 points: the one, fix and will fill mutually all even tight appropriateness, in post, do not leave deadVolume or gap; The 2nd, avoid beaing in filling process vibration too quickly, cause fixed camera tool to pulverize.
