Abstract
A kind of bottle cap of different-diameter pore and different liquids volatile quantity, by screw cap main body, pore, gasket and screw thread composition, bottle cap, which is tightened on corresponding thread bottle, makes bottle seal.The bottle cap of the pore of different-diameter can obtain the volatile quantity of different liquids.The bottle cap of this different inner diameters pore can be used as the releasing unit of dopant.
Description
Technical field
The utility model is related to ion mobility spectrometry and mass-spectrometric technique, specifically a kind of different-diameter pore and the amount of evaporating
Bottle cap.
Background technology
Ion mobility spectrometry and mass spectrum are a kind of detection techniques of trace gas sample, and it is auxiliary to be typically employed to dopant
Help ionized sample molecule and generate sample ions, dopant is connected in the gas circuit of sample carrier gas, the burst size of dopant and
Concentration level in carrier gas affects the speed and ion concentration for generating sample ions.The concentration of dopant is by dopant
Open pore size size on the influences such as burst size, temperature, flow rate of carrier gas, class of liquids, wherein burst size and dopant bottle cap and
Trepanning length etc. is closely related.
The bottle cap of a kind of the different-diameter pore and different liquids volatile quantity of the utility model, by bottle cap body (1) and ring
Shape gasket (3) forms；Bottle cap body lower face is equipped with the blind round hole with internal thread (4), is equipped in the middle part of blind hole bottom surface
One through-hole (2) is equipped with annular groove in the bottom surface of blind hole at side wall surface, is equipped with ring seal pad (3) in annular groove, leads to
Hole (2) is in inside the region that annular groove is surrounded.Bottle cap, which is tightened on corresponding thread bottle, makes bottle seal.Different-diameter
The bottle cap of pore 2, the volatile quantity for discharging liquid are different.By making the bottle cap of different-diameter pore, can be evaporated
Measure different bottle caps.
The bottle cap of this different liquids volatile quantity can be used as the releasing unit of dopant.
Utility model content
The purpose of this utility model is to provide a kind of bottle cap of different-diameter pore and different liquids volatile quantity, including bottle cap
Main body (1) and Gask-O-Seal (3)；Bottle cap body lower face is equipped with the blind round hole with internal thread (4), in blind hole bottom surface
Portion is equipped with a through-hole (2), is equipped with annular groove at side wall surface in the bottom surface of blind hole, ring seal pad is equipped in annular groove
(3), through-hole (2) is in inside the region that annular groove is surrounded.
The bore dia of through-hole (2) is between 5 microns to 500 microns.
The hole length of through-hole (2) is between 4 millimeters to 30 millimeters；
Bottle cap is tightened in by internal thread in the opening accordingly with external screw thread open bottles, and Gask-O-Seal (3) bottle is passed through
It is sealed between lid and open bottles.
Cyclic sealing gasket can be that integral type passes through ramp structure and spiral shell using identical material with screw cap main body
Line bottle is sealed.
Bottle cap is by being screwed on corresponding thread bottle, by being sealed between 3 bottle cap of gasket and thread bottle；
The bottle cap of different-diameter pore 2, the volatile quantity for discharging liquid are different.By making the bottle cap of different-diameter pore,
It can obtain the different bottle cap of the amount of evaporating.
Description of the drawings
Fig. 1 is the bottle cap schematic diagram of a kind of different-diameter pore and different liquids volatile quantity.
Wherein, 1 is screw cap main body, and 2 be pore, and 3 be gasket, and 4 be screw thread.
