Abstract
The utility model relates to an efficient liquid phase chromatic spectrum moving bidirectional sample-feeding device of moving wire detector, which can be used for the analysis of high point hydrocarbon. The utility model is composed of a mobile table frame, evaporation blocks, an atomizing spraying implement, a metal moving wire, an oxidation quartz tube, a molecule entrainment implement, a catalytic reduction chamber, a flame ionization detector (FID), etc. Compared with the existing moving wire detector, the moving wire of the utility model can undertake the works of the cleanness of the moving wire, the load bearing of the analysis sample and the oxidation combustion in the repeated operation, which can simplify the operational procedure, reduce the abrasion of the moving wire and enhance the efficiency of analysis working.
Description
The utility model is the device that is used for the high performance liquid chromatography moving wire detector, and or rather, it is the sampling device that is used for the high performance liquid chromatography moving wire detector of higher boiling hydrocarbon ils family analysis, belongs to the liquid chromatography technology field.
The utility model is the improvement to the CN93216473.0 utility model patent.This utility model patent is a kind of high performance liquid chromatography moving wire detector that higher boiling hydrocarbon ils family analyzes that is used for.It is moved silk, oxidation quartz ampoule, cleaning quartz ampoule, molecule entrainment device, catalytic reduction chamber, is reached flame ionization detector parts such as (FID) formation by mobile stand, evaporation piece, atomizing spraying device, metal.It is in the process of using, be sprayed on metal by isolated each hydrocarbon system's sample in the performance liquid chromatographic column together with rinse solvent and move on the silk, after the solvent evaporation, sample burns into carbon dioxide in the oxidation quartz ampoule, change into methane through catalytic reduction again, after the FID detection.The metal of its carrying sample moves silk and is wrapped on the wire feeding shaft, has certain length.When mobile silk runs to terminal point, proceed in order to make analysis operation, adopt two kinds of methods that the gear train that moves silk is resumed operation usually.First method is to move silk fully around top wire drawing wheel with become taking off respectively for the silk wheel of empty wheel, will move again behind the transposition thread to pass and clean quartz ampoule and oxidation quartz ampoule.So not only require operating personnel that a twist of the wrist is arranged, and will the running of stop detector before wearing silk again, just need the long period and return to duty again.Second method is to use the wire inversion way of this utility model patent suggestion, returns with opposite direction moving silk, unrolls on wire feeding shaft.Though this method is simpler than first method in operation, the used time is not short yet; Metal moves silk and also will change the wire inversion guide wheel that passes through when wire inversion, has increased the wearing and tearing of mobile silk.
The purpose of this utility model is exactly the shortcoming that exists at above-mentioned two kinds of wire inversion methods, on individual other parts, improved, make mobile silk in service what come and go, all born the cleaning of mobile silk, the carrying of sample and oxidizing fire work, simplify the operation, reduce the wearing and tearing of moving silk, improve analytical work efficient.
The utility model is on the basis of above-mentioned CN93216473.0 utility model patent, will move silk and change two-way sample introduction into, and will clean quartz ampoule and oxidation quartz ampoule along with the trend that moves silk, intersects to change to play a part to clean and oxidation.For this reason, at an end of original cleaning quartz ampoule, increase an outlet stool; Between original oxidation quartz ampoule, cleaning quartz ampoule and molecule entrainment device, increase the three-way valve that valve core is a hexagonal angle; And with the mobile stand of atomizing spraying device, evaporating solvent and evaporate packaged can be on the suspension that moves between cleaning quartz ampoule and oxidation quartz ampoule and realized the above object at one.
Realize the concrete measure of above purpose below in conjunction with description of drawings.For the ease of comparing, Fig. 1 is the original parts connection layout of CN93216473.0, and Fig. 2 and Fig. 3 are the improvement parts connection layout that the utility model is done.Parts code name in the accompanying drawing 1,2, the 3 all part number with CN93216473.0 is consistent.
In the parts connection layout of the CN93216473.0 of Fig. 1, be introduced into the cleaning quartz ampoule 13 that cleans in the stove 12 by the mobile silk of supplying with for silk wheel shaft 11 3, burn and stick to the organism that moves on the silk, the mobile silk of cleaning drives (guide wheel 14 rotates counter clockwise) by guide wheel 14, bears sample below atomizing spraying device 2.By 1, with most of rinse solvent evaporation, concentrated sample drops in and moves on the silk 3 through atomizing spraying device 2 by isolated sample and rinse solvent in the performance liquid chromatographic column.Move forward along with moving silk 3, concentrate the evaporation piece 4 of sample through mobile stand and temperature controllable, rinse solvent is evaporated fully, sample enters in the oxidation quartz ampoule 6 of oxidation furnace 5 immediately.Owing to all have air to enter at the two ends of oxidation quartz ampoule 6, the CO that generates after sample fully burns
2Gas enters in the molecule entrainment device 7 in company with unnecessary air.The other end at molecule binder 7 has hydrogen and nitrogen to send into, the CO that the sample burning generates
2Carried secretly in the catalytic reduction chamber 9 that enters catalyst furnace 8 by hydrogen and nitrogen.Under the effect of Raney nickel, CO
2Be reduced into methane gasometry, enter then in the flame ionization detector (FID) 10.Methane is burnt in FID, and the signal that FID provides is noted by register or integraph after amplifier amplifies.The mobile silk 3 that comes out from oxidation quartz ampoule 6 is wrapped on the wire drawing wheel axle 15 through guide wheel group and thread arranging device again.
Fig. 2 and Fig. 3 are the utility model to the improvement synoptic diagram that CN93216473.0 did.The utility model is connected in series a T-valve 30 in the pipeline that exports to molecule entrainment device 7 of oxidation quartz ampoule 6, its valve core is the bilateral of hexagonal angle.At one mouth of pipe of inlet end increase of cleaning quartz ampoule, this mouth of pipe is connected on the other end of T-valve 30 through pipeline.By the valve core turned position of T-valve 30, molecule entrainment device 7 can connect with oxidation quartz ampoule 6 or cleaning quartz ampoule 13; And according to the position of threeway valve core and the trend of mobile silk, quartz ampoule 6 and quartz ampoule 13 just cross one another and play a part oxidation sample and clean mobile.Inhour according to the valve core position of T-valve among Fig. 2 30 and guide wheel 14 is rotated direction, the effect of quartz ampoule 6, quartz ampoule 13, wheel shaft 11, wheel shaft 15 all with Fig. 1 in consistent.When the mobile silk 3 on wheel shaft 11 will be at the end, just the trend that moves silk 3 is switched.Signal according to Fig. 3, adjust earlier the temperature of heating furnace 5 and heating furnace 12 rapidly, rotate the valve core position of T-valve 30, quartz ampoule 6 and molecule entrainment device 7 are disconnected, quartz ampoule 13 and molecule entrainment device 7 are communicated with, change turn to (with the switched in opposite among Fig. 2) of wheel shaft 11, wheel shaft 15 and guide wheel 14, and the suspension of mobile stand that is loaded with atomizing spraying device 2, evaporating solvent and evaporation piece 4 is shifted to the porch of quartz ampoule 13.Through above blocked operation, move silk 3 and just move operation according to the direction of arrow shown in Fig. 3,15 become for the silk wheel shaft, and 11 become the wire drawing wheel axle, and quartz ampoule 6 becomes the cleaning quartz ampoule, and quartz ampoule 13 becomes the oxidation quartz ampoule.Can realize the two-way sample introduction analysis of mobile silk 3 according to improvement design of the present utility model.After moving silk switchover operation direction, in ten minutes, just can return to normal analytical work state.Compare with CN93216473.0, have simple to operate, the advantage that prolong to move silk serviceable life and save analysis operation time.
