The upper surface of lower cover is provided with groove, and the through hole for running through is provided with center, is provided with the lower surface of lower cover The mounting hole of adapter;
Film is arranged on the upper surface of lower cover by supporting lining net, and is compressed by upper press cover, between upper press cover, lower cover It is provided with sealing ring;Adapter is arranged on the lower surface of lower cover;
Two-bit triplet magnetic valve is provided with decompression micropore, and normal-closed end and the four-electrode spectrum system of two-bit triplet magnetic valve connect Connect, two ends are connected with membrane pump, adapter respectively in addition.
Beneficial effect:The sample introduction that the utility model is applied to online ionic pump four-electrode spectrum system is used, simple structure, rich Collect efficiency high, fast response time, can ensure that vacuum system is not destroyed safe and reliable and long service life.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Specific embodiment
Developed simultaneously embodiment below in conjunction with the accompanying drawings, and the utility model is described in detail.
Referring to accompanying drawing 1, the film sampling device of online ionic pump four-electrode spectrum system, it includes:Upper press cover 1, lower cover 2, Film 3, adapter 6 and two-bit triplet magnetic valve 7;
Upper press cover 1 is respectively arranged on the left side and the right side the gas passage communicated with lower surface, wherein one is air intake duct 11, separately One is air exhaust duct 12;Air intake duct 11 is located at the relative position in the two sides of upper press cover 1 with air exhaust duct 12, can be effectively increased gas and exist The flow distance on the surface of film 3, improves the effective area of film 3, improves bioaccumulation efficiency.
The upper surface of lower cover 5 is provided with groove, and the through hole for running through is provided with center, is set in the lower surface of lower cover 5 There is the mounting hole of adapter 6;
Film 3 is arranged on the upper surface of lower cover 5 by supporting lining net 2, and is compressed by upper press cover 1, in upper press cover 1, pushes Sealing ring 4 is provided between lid 5, sealing ring uses silastic material, it is to avoid the absorption of material for gaseous;Adapter 6 is arranged on down The lower surface of gland 5;
Two-bit triplet magnetic valve 7 is provided with decompression micropore, and normal-closed end and the four-electrode spectrum system of two-bit triplet magnetic valve 7 connect Connect, one end is connected by tubule 8 (1/16 stainless steel tube) with adapter 6, and the other end is connected with membrane pump;Pipeline uses cutting ferrule Formula pipe joint is attached, not only easy disassembly but also safe and reliable.
The utility model two-position three-way valve 6 when not working is normally closed ensureing that the vacuum of four-electrode spectrum system is not destroyed.
The utility model is simultaneously using the membrane pump being connected on two-bit triplet magnetic valve 6 and installed in two-bit triplet electromagnetism Micropore in the valve body of valve 6 is depressurized, and reduces the pressure difference in injection port and four-electrode spectrum system, it is ensured that in four-electrode spectrum system Vacuum is maintained at rational scope.
The course of work of the present utility model is as follows:Gas is pumped into sampling device by aspiration pump, one due to pressure difference Divide gas to be enriched with the part entered behind sample introduction film 3 by film 3, by the decompression of membrane pump and micropore, eventually enter into quadrupole matter Spectra system;Sample introduction whether switching is carried out by controlling two-bit triplet magnetic valve 6.
In sum, preferred embodiment of the present utility model is these are only, is not intended to limit of the present utility model Protection domain.It is all it is of the present utility model spirit and principle within, any modification, equivalent substitution and improvements made etc. all should be wrapped It is contained within protection domain of the present utility model.
