Description
Technical field
The utility model relates to LCD photosensitive material production and uses pick-up unit, specifically is that a kind of LCD photosensitive material detects the carrier gas system with gas chromatograph.
Background technology
During chemical products were produced, the necessity of quality analysis, promptness, accuracy were self-evident, and fine chemistry industry is all the more so.
Gas chromatography is that the gaseous matter or the material that can be converted into gas are at a certain temperature carried out check and analysis.Because the rerum natura of material is different, each component is different with the partition factor between the immobile liquid liquid phase in gas phase in its sample, and the sample after gasifying is brought into when moving in the chromatographic column by carrier gas; Component is distributed with regard to the two alternate repeated multiple times of carrying out therein, because stationary phase is different to the absorption or the dissolving power of each component, through after the flowing of certain hour; Just separated from one another; Leave chromatographic column in order and get into detecting device, the signal of generation is depicted the chromatographic peak of each component on register after amplifying.According to going out the peak position, confirm the title of composition, confirm concentration according to peak area, the principle of work of Here it is gas chromatograph.
The used carrier gas of different detection sample is inequality, if equipment has in limited time, can only adjust required instrument according to different sample ventilations.
LCD photosensitive material detects carrier gas commonly used has three kinds of hydrogen, nitrogen, helium.Adorn a reduction valve on the previous gas cylinder of order, reduction valve connects gas circuit, is connected on the gas chromatograph to air purifier; One end that will connect air purifier during ventilation is pulled down, and is connected on the required instrument, and process is loaded down with trivial details, lose time; And instrument and pipeline connecting portion are because frequent dismounting is fragile; The bad grasp of the impermeability of instrument is changed once and must be proofreaied and correct once, has increased workload.
The utility model content
In order to overcome the shortcoming that above-mentioned prior art exists; The purpose of the utility model is to provide a kind of LCD photosensitive material to detect the carrier gas system with gas chromatograph; It when ventilation without closing device, detaching pipelines; Swift and convenient to operate, can not delay operate as normal, and avoid of the infringement of frequent disassembling pipe instrument.
For addressing the above problem, the utility model adopts following technical scheme: this LCD photosensitive material detects the carrier gas system with gas chromatograph, comprises three gas cylinders that different carrier gas are housed, and a reduction valve is installed on each gas cylinder; Also comprise air purifier, air purifier comprises first air intake opening, second air intake opening; The output terminal of air purifier connects gas chromatograph; Three gas cylinders connect first gas circuit, second gas circuit, the 3rd gas circuit through separately reduction valve respectively; Said first gas circuit parallel connection, first retaining valve, second retaining valve, parallel connection the 3rd retaining valve, the 4th retaining valve are provided with the 5th retaining valve on second gas circuit on the 3rd gas circuit; The output terminal of said first retaining valve, the 3rd retaining valve converges and is communicated to first air intake opening; The output terminal of first retaining valve, the 5th retaining valve converges and is communicated to first air intake opening; The output terminal of second retaining valve, the 4th retaining valve converges and is communicated to second air intake opening; The output terminal of the 3rd retaining valve, the 5th retaining valve converges and is communicated to first air intake opening.
The beneficial effect of the utility model is: it without closing device, detaching pipelines, can realize ventilation through the operation retaining valve when ventilation, swift and convenient to operate, can not delay operate as normal, and avoid the infringement of frequent disassembling pipe to instrument; And many gas chromatographs can parallel connection use a cover carrier gas system.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further explanation:
Fig. 1 is the structural representation of the utility model embodiment,
Among the figure: 1 gas cylinder, 2 reduction valve, 3 first gas circuits, 31 first retaining valves, 32 second retaining valves; 4 second gas circuits, 41 the 3rd retaining valves, 42 the 4th retaining valves, 5 the 3rd gas circuits, 51 the 5th retaining valves; 6 air purifiers, 61 first air intake openings, 62 second air intake openings, 7 gas chromatographs.
Embodiment
As shown in Figure 1, the carrier gas system that this LCD photosensitive material detects with gas chromatograph comprises three gas cylinders 1 that different carrier gas are housed, and a reduction valve 2 is installed on each gas cylinder 1; Also comprise air purifier 6, air purifier 6 comprises first air intake opening 61, second air intake opening 62; The output terminal of air purifier 6 connects gas chromatograph 7.
