Abstract
The utility model discloses a capillary chromatographic column liner device for a gas chromatograph detector and belongs to the technical field of analysis testing instruments. A stainless steel pipe structure is adopted; bevels in which a detector and a column joint can be conveniently installed are arranged at two ends of a stainless steel pipe; a horn mouth through which the tail of a capillary chromatographic column smoothly enters a capillary chromatographic column liner is formed in an inner hole of the lower end of the stainless steel pipe; a drainage groove through which make-up gas can smoothly enter the detector is formed in the upper end of the stainless steel pipe; a make-up gas drainage hole is formed in the upper one-third part; part of the make-up gas is drained into the inner hole and flows upwards from the tail of the capillary chromatographic column into the detector. The gas pressure formed by passing of the make-up gas which flows into the detector from the outer wall of a liner pipe through the upper end of the liner pipe is eliminated, so that components, which flow out of the tail of the capillary chromatographic column and are separated by the capillary chromatographic column, smoothly flow into the detector.
Description
Technical field
The utility model belongs to the analytical and testing instrument technical field, relates to a kind of inner lining structure design of gas chromatograph detecting device capillary chromatographic column.
Background technology
When gas chromatograph is done analysis with capillary chromatographic column, the quality of capillary chromatographic column tail and detecting device interconnection technique, directly affect gas chromatograph and make the usefulness of analysis of capillary chromatographic column.General capillary chromatographic column tail and detecting device connection request.1. the dead volume that the capillary chromatographic column tail is connected with detecting device is little; 2. the capillary chromatographic column tail can enter capillary chromatographic column liner Shunda detecting device root smoothly; 3. make-up gas can enter detecting device smoothly; 4. the component that the capillary chromatographic column wake flow goes out after being separated by capillary chromatographic column flows into detecting device smoothly; 5. the capillary chromatographic column inner lining apparatus is durable.Based on above consideration, when the capillary chromatographic column tail is connected with detecting device, adopt the capillary chromatographic column inner lining apparatus more.At present, the gas chromatograph inner lining structure designs, and adopts glass tube or the quartz ampoule of suitable length, diameter and endoporus more.Although can meet the little requirement of dead volume that the capillary chromatographic column tail is connected with detecting device, also have many shortcomings: 1. thinner because of the hole in the middle of internal lining pipe, the capillary chromatographic column tail can not enter the capillary chromatographic column liner smoothly; 2. because make-up gas flows into detecting device by the internal lining pipe outer wall, make-up gas is stopped up by the internal lining pipe upper end sometimes, can not enter smoothly detecting device; 3. sometimes wear the top less than internal lining pipe because of capillary chromatographic column, the make-up gas that is flowed into detecting device by the internal lining pipe outer wall is during by the internal lining pipe upper end, just at the inner orifice place of internal lining pipe upper end, form certain air pressure, cause the capillary chromatographic column wake flow to go out by capillary chromatographic column, separated after component can not flow into smoothly detecting device; 4. glass tube or quartz ampoule are frangible.
Summary of the invention
The utility model provides a kind of gas chromatograph detecting device capillary chromatographic column inner lining apparatus, it is characterized in that: adopt the stainless-steel tube structure, there is the chamfering of conveniently pack into detecting device and column joint at two ends, there is the hydraucone that makes the capillary chromatographic column tail enter smoothly the capillary chromatographic column liner at the endoporus place of lower end, there is the drainage trough that can make make-up gas enter smoothly detecting device upper end, there is the make-up gas conduction hole at top 1/3rd places, the part make-up gas is introduced in endoporus, upwards flow into detecting device from capillary chromatographic column tail bottom, eliminated the air pressure that the make-up gas that flows into detecting device by the internal lining pipe outer wall forms during by the internal lining pipe upper end, so that the capillary chromatographic column wake flow is gone out by capillary chromatographic column, separated after component flow into smoothly detecting device.
The beneficial effects of the utility model: solved gas chromatograph detecting device capillary chromatographic column inner lining apparatus weak effect, not handy, short-life problem, guaranteed that gas chromatograph makes the usefulness of analysis of capillary chromatographic column.
The accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Accompanying drawing is the utility model gas chromatograph detecting device capillary chromatographic column inner lining apparatus.
1. stainless-steel tubes in accompanying drawing, 2. conduction hole, 3. endoporus, 4. hydraucone, 5. chamfering, 6. drainage trough.
Embodiment
Embodiment is, on stainless-steel tube (1), the chamfering (5) of can conveniently pack into detecting device and column joint is processed at two ends, the hydraucone (4) that can make the capillary chromatographic column tail enter smoothly the capillary chromatographic column liner is processed in lower end, the make-up gas drainage trough (6) that can make make-up gas enter smoothly detecting device is processed in upper end, top 1/3rd places processing make-up gas conduction holes (2), so as the capillary chromatographic column wake flow to be gone out by capillary chromatographic column, separated after component flow into smoothly detecting device.
Claims (1)
1. a gas chromatograph detecting device capillary chromatographic column inner lining apparatus, it is characterized in that: adopt the stainless-steel tube structure, there is the chamfering of conveniently pack into detecting device and column joint at two ends, there is the hydraucone that makes the capillary chromatographic column tail enter smoothly the capillary chromatographic column liner at the endoporus place of lower end, there is the drainage trough that can make make-up gas enter smoothly detecting device upper end, and there is the make-up gas conduction hole at top 1/3rd places.
