Description
Technical field
The invention belongs to instrument maintenance instrument and application, be specifically related to the clear of a kind of shunting/Splitless injecting samples mouth
Wash external member and using method thereof.
Background technology
Gas chromatograph and the feature that gas chromatograph-mass spectrometer is high with its precision, qualitative, quantitative is effective are being eaten
Being used widely in multiple fields such as product, cosmetics, oil, is pesticide residues, residue of veterinary drug and other multiple Harmful chemicals
The important means of retention analysis.
The operation principle of gas chromatograph and gas chromatograph-mass spectrometer is typically to utilize detected object easily to vaporize
Feature, by detected object at shunting/Splitless injecting samples mouth rapid vaporization, the gaseous state measured target thing of formation is in carrier gas
Realize separating with interfering material through capillary tube or filling detached dowel under drive, arrive detector afterwards and be detected and by chromatograph
Workstation software is converted into recognizable chromatogram or mass spectrum, thus realizes the purpose of qualitative analysis and detection by quantitative.
Wherein, shunting/Splitless injecting samples mouth analyzes most important parts as gas chromatogram or gas chromatography combined with mass spectrometry
One of, in realizing trace analysis, play vital effect.According to statistics, the clean level of shunting/Splitless injecting samples mouth is
Affect gas chromatograph and gas chromatograph-mass spectrometer produces the key factor of qualitatively and quantitatively accuracy.When shunting/regardless of
When polluting occurs in stream injection port, would generally there is target peak disappearance, peak shape not in gas chromatograph and gas chromatograph-mass spectrometer
Symmetrical or hangover, the problems such as ghost peak or peak division, instrument quantitative bad stability occur.Have based on this, in application gas phase
When chromatograph and gas chromatograph-mass spectrometer carry out trace analysis, needs conscientiously clean, safeguard shunting/Splitless injecting samples mouth,
To obtain qualitative, quantitative effect accurately.
In the regular maintenance of shunting/Splitless injecting samples mouth, such as dottle pin, round section joint ring, bushing pipe, chromatographic column, reducing nut
All can dismantle Deng the related accessory at injection port position, intercept, change and clean.But the welding of shunting/Splitless injecting samples mouth
Part is owing to being welded on heating module, it is impossible to dismounting, it is difficult to clean, thus becomes shunting/Splitless injecting samples mouth and safeguard, clearly
The difficult point washed.
Currently, clean, safeguard shunting/Splitless injecting samples mouth method be typically with cotton swab dip organic solvent to shunting/
Wiping is carried out inside Splitless injecting samples mouth weldment.But owing to cotton swab absorbent cotton part is little compared with weldment internal diameter, absorbent cotton and weldering
Inside fitting, laminating degree is the highest, and cotton swab force-applied less, be prone to shortcomings such as fractureing, cause this kind of mode effectively to remove
The pollutant of residual inside shunting/Splitless injecting samples mouth weldment.
Summary of the invention
In order to solve currently to shunt/Splitless injecting samples mouth cleans the problem of difficulty, it is contemplated that in provide one shunting/
The cleaning external member of Splitless injecting samples mouth and using method thereof, to meeting the mesh quickly, thoroughly cleaning shunting/Splitless injecting samples mouth
Mark.
The present invention is achieved through the following technical solutions above-mentioned target.
The cleaning external member of a kind of shunting/Splitless injecting samples mouth, including assembly I and assembly II, wherein assembly I is by ring 1, gold
Belong to bar 2 and bristle 3 forms;Assembly II is made up of cylindrical handle 4 and cylinder 5, it is characterised in that cylinder 5 lower end of assembly II
There is a groove 7 in part, this groove exists the upper age of a draught animal 6 and the lower age of a draught animal 8.
Wherein,
Described assembly I is positioned at the bristle lengths of metallic rod 2 one side isometric and for 3mm to 4mm.
A diameter of 5mm to 6mm of the cylinder 5 of described assembly II.
The using method of the cleaning external member of a kind of shunting/Splitless injecting samples mouth comprises the following steps:
Step one, prepares: by the dottle pin of shunting/Splitless injecting samples mouth, round section joint ring, bushing pipe, chromatographic column, reducing nut etc.
Shunting/Splitless injecting samples mouth accessory is removed, and exposes shunting/Splitless injecting samples mouth;
Step 2, scrubs: place a beaker in the lower end of injection port, dips methanol with assembly I and scrubs shunting/no up and down
Inside split sampling mouth weldment, repeat 10 to 20 times;Afterwards, dip acetone solvent with assembly I and scrub shunting/do not shunt up and down
Inside injection port weldment, repeat 10 to 20 times;
Step 3, wiping: fill up the groove 7 of assembly II after absorbent cotton is dipped methanol, the cylinder 5 of assembly II is inserted point
Inside stream/Splitless injecting samples mouth weldment, repeat wiping 10 to 20 times up and down, discard absorbent cotton;Afterwards, absorbent cotton is dipped third
Fill up the groove 7 of assembly II after ketone, the cylinder 5 of assembly II is inserted inside shunting/Splitless injecting samples mouth weldment, repeat up and down
Wiping 10 to 20 times.
Step 4, drip washing and being dried: draw the acetone of 10mL to 20mL and normal hexane solvent washing injection port successively, treat point
The solvent of stream/Splitless injecting samples mouth evaporates into dry naturally.
It is an advantage of the current invention that:
(1) shunting of the present invention/Splitless injecting samples mouth clean external member have easy and simple to handle, clean the most notable
Advantage;
(2) assembly I bristle lengths of the present invention is slightly larger than shunting/Splitless injecting samples mouth weldment internal diameter, is dipping in
The residual contaminants inside weldment can be cleaned by External Force Acting after taking organic solvent;
(3) after in assembly II of the present invention, the groove part of cylinder fills the absorbent cotton dipping organic solvent, cotton
Loop diameter is slightly larger than shunting/Splitless injecting samples mouth internal diameter, under external force can high laminating degree by inside weldment through assembly I
The thorough wiped clean of residual contaminants after scrubbing, simultaneously because groove 7 exists the upper and lower age of a draught animal 6 and 8, absorbent cotton welds at injection port
Do not come off when moving up and down inside fitting.
