Preferably, first sealing ring is located at the top of the second sealing ring.
Preferably, the cylinder is located at the front side of slide platform.
Preferably, the top on rear side of the aqueous cold plate on front side of low vacuum cavity with being fixedly connected.
Preferably, the low vacuum cavity is located at the top of the first sealing ring.
Compared with prior art, beneficial effects of the present invention are as follows：
1st, the present invention is by setting igniting cavity, the first sealing ring, the second sealing ring, slide platform, cylinder, aqueous cold plate and low true
Cavity body is used cooperatively, and it is poor to solve the sealing joint effect of existing icp ms low vacuum, no
It can quickly realize the conversion of normal barometric pressure and low vacuum, be not easy to the problem of installation is safeguarded, the inductivity coupled plasma mass spectrometry
The interface of instrument low vacuum, possesses that sealing effect is good, can quickly realize the conversion of normal barometric pressure and low vacuum, be easily installed maintenance
Advantage, improves the low practicality of existing icp ms, is worthy to be popularized.
2nd, the present invention enhances the icp ms by setting the first sealing ring and the second sealing ring
The sealing effect of the interface of low vacuum.
