This scheme of adoption can effectively prevent cross contamination's problem to improve the analysis accuracy, practice thrift the washing time, improve analysis speed.
Description
Technical Field
The utility model belongs to the technical field of sample analysis technique and specifically relates to indicate the liquid feeding bottle that plasma emission spectrometer used.
Background
In ICP-OES analysis of samples, a liquid inlet pipe is inserted into a sample to extract liquid for analysis, and when a plurality of samples are analyzed, residual elements in the liquid inlet pipe pollute other samples, particularly, accumulated pollution phenomenon exists during standard liquid calibration.
Disclosure of Invention
An object of the utility model is to overcome prior art's not enough, provide a plasma emission spectrometer that improves analysis accuracy, practices thrift the flushing time, improves analysis speed and uses the liquid feeding bottle.
In order to achieve the above object, the present invention provides a technical solution: the liquid inlet bottle for the plasma emission spectrometer comprises a bottle body, wherein the top of the bottle body is meshed with a bottle cover, the top of the bottle cover is provided with a luer-penetrating plate male head, a liquid taking pipe is connected onto the luer-penetrating plate male head in the bottle body, the lower part of the liquid taking pipe is positioned at the lower part of an inner cavity of the bottle body, a liquid inlet pipe is connected onto the luer-penetrating plate male head outside the bottle body, the outer end of the liquid inlet pipe is connected with a speed increasing pipe, and a flow control valve.
The flow control valve comprises a cylindrical guide pillar which is horizontally installed, an arc-shaped liquid control plate is installed on the upper portion of the guide pillar through an adjusting bolt, the inner arc surface of the arc-shaped liquid control plate faces downwards, a liquid inlet pipe channel is reserved between the arc-shaped liquid control plate and the guide pillar, an arc-shaped guide plate with the inner arc surface facing upwards is arranged below the guide pillar, guide grooves with the quantity larger than 2 are formed in two sides of the arc-shaped guide plate, and liquid inlet pipes are output after penetrating through the guide grooves and the liquid inlet pipe channel.
The inner diameter of the liquid inlet pipe is 2-2.5mm, the outer diameter of the speed increasing pipe is 1.8-2.4mm, and the liquid inlet pipe is provided with a luer female head.
The liquid taking tube is 15-20cm long and 1-2mm in inner diameter.
By adopting the above technical scheme, the utility model, be equipped with on sample bottle (bottle) and luer wear the public head of board, the lower part is long with 15cm, and internal diameter 2mm polytetrafluoroethylene union coupling sheathes an external diameter 2mm in 2mm polytetrafluoroethylene inside again, and internal diameter 1 mm's polytetrafluoroethylene pipe to this internal diameter reduces and improves the velocity of flow, reduces the sample introduction time. A luer female head is arranged on a liquid inlet pipe on the ICP-OES, and the luer male head and the luer female head can be matched and butted with each other. After the device is used, the corresponding liquid inlet pipe is replaced, so that the problem of cross contamination can be effectively prevented, the analysis accuracy is improved, the washing time is saved, and the analysis speed is improved.
Drawings
Fig. 1 is a schematic view of the overall structure of the present invention.
Detailed Description
The present invention will be further explained with reference to the drawings, and the preferred embodiment of the present invention is: referring to fig. 1, the liquid inlet bottle for the plasma emission spectrometer according to the present embodiment includes a bottle body 1, a bottle cap 2 is engaged with the top of the bottle body 1, a luer-insert plate male head 3 is installed on the top of the bottle cap 2, a liquid taking tube 4 is connected to the luer-insert plate male head 3 in the bottle body 1, the liquid taking tube 4 has a length of 15-20cm and an inner diameter of 1-2mm, the lower portion of the liquid taking tube 4 is located at the lower portion of an inner cavity of the bottle body 1, a liquid inlet tube 9 is connected to the luer-insert plate male head 3 on the outer side of the bottle body 1, an acceleration tube 5 is connected to the. Flow control valve 6 is including being horizontal installation's columniform guide pillar, and arc accuse liquid board 7 is installed through adjusting bolt on guide pillar upper portion, and the inner arc face of arc accuse liquid board 7 is downward, and it has the feed liquor pipe passageway to reserve between arc accuse liquid board 7 and the guide pillar, and the guide pillar below is equipped with the upward arc deflector 8 of inner arc face, and 8 both sides of arc deflector are equipped with the guide way that quantity is greater than 2, and output behind feed liquor pipe 9 passed guide way, the feed liquor pipe passageway. The inner diameter of the liquid inlet pipe 9 is 2-2.5mm, the outer diameter of the speed increasing pipe 5 is 1.8-2.4mm, and the liquid inlet pipe 9 is provided with a luer female head.
