Abstract
The invention provides a special apparatus for coating a gas-phase capillary column for a chromatographic analysis test, which is simple in structure, convenient to operate, safe and reliable, and has the characteristics of low manufacture cost, compact layout of parts and high maneuverability. The special apparatus comprises a bottom plate (1), a vertical plate (2), a nitrogen switch (3), a flow regulating valve (4), a gas pressure meter (5), the capillary column (6), a nitrogen inlet (7), a coating groove (8) and a sample bottle (9), wherein the bottom plate (1) and the vertical plate (2) are made of steel plates, and chrome-faced to be prevented from being rusted, and the coating groove (8) and various pipe joints and a nitrogen conveying capillary are made of stainless steel materials. The nitrogen switch (3) is connected with a nitrogen bottle, the gas pressure and the flow are regulated through the flow regulating valve (4), nitrogen enters the coating groove (8) through the nitrogen inlet (7) in the side surface of the upper part of the coating groove (8), and is subjected to gradual pressure regulation to reach a proper pressure and flow, and a sample material is pressed in the capillary column from the sample bottle for coating the capillary column.
Description
(1) technical field
The present invention relates to a kind of gas chromatography and be coated with the stain Special instrument, especially a kind of simple in structure, easy to operate, safe and reliable stratographic analysis test is coated with stain specialized equipment instrument with gas chromatography, belongs to chemical analysis apparatus technical field.
(2) background technology
During present domestic gas chromatographic analysis test, the kapillary column coating does not have special-purpose instrument and equipment, and the kapillary column coating can only rely on the homemade easy device of experimenter, complicated operation, wayward, easily damage kapillary, the painting stain of capillary column is discontinuous, and success ratio is not high, inefficiency.
(3) summary of the invention
The present invention, in order to make up the deficiencies in the prior art, provides gas chromatography a kind of simple in structure, easy to operate, safe and reliable to be coated with the stain Special instrument, be characterized in simple in structure, volume is little, cost is low, parts compact in design, rationally, safe, workable.
(4) accompanying drawing explanation
Accompanying drawing is the structural representation that gas chromatography is coated with the stain Special instrument.
Wherein: 1 base plate, 2 risers, 3 nitrogen switches, 4 flow control valves, 5 rain glasss, 6 capillary columns, 7 nitrogen inlets, 8 are coated with stain groove, 9 sample plasma bottles.
(5) embodiment
For gas chromatography of the present invention, be coated with as shown in drawings a kind of specific embodiment of stain Special instrument.Comprise: base plate (1), riser (2), nitrogen switch (3), flow control valve (4), rain glass (5), capillary column (6), nitrogen inlet (7), be coated with stain groove (8), sample plasma bottle (9).Wherein base plate (1) and riser (2) are to use the steel plate processing and fabricating, and chrome-faced is antirust, between base plate (1) and riser (2), with screw, is connected and fixed.Sample plasma bottle (9) is vial, during use, is positioned over and is coated with in stain groove (8), and being coated with stain groove inner bottom part has a rubber blanket, and being coated with stain groove (8) is to be fixed on base plate (1) by 4 screws on base.Nitrogen switch (3) is connected with nitrogen cylinder, pass through again flow control valve (4) adjustable pressure and flow, the size of air pressure is by rain glass (5) demonstration, and nitrogen enters to be coated with through the nitrogen inlet (7) that is coated with stain groove (8) upper side and steeps groove (8); Being coated with stain groove (8) and various pipe adapter and nitrogen carries tubule all with stainless steel material, to make, be coated with between the upper end lid of stain groove (8) and cell body by screw tightening, and, by seal with elastometic washer, above the groove lid, a nut that can insert kapillary and seal by O-ring seal is arranged.During the kapillary column coating, first the liquid sample material is poured in sample plasma bottle (9), again sample plasma bottle (9) is put in and is coated with in the stain groove, tighten the nut of upper end, after inserting capillary column (6), open nitrogen switch (3), progressively pressure regulation is to suitable pressure and flow, and the pressure of nitrogen is pressed into the liquid sample material capillary column from sample plasma bottle (9), just can carry out the kapillary column coating.
