This part is used in the field of scientific instruments, for an ignition chamber in a mass spectrometer.The material selected is aluminum 6061
The mini rod of the quadrupole mass analyzer is the key heart of the gas phase detector, which is composed of four precision parallel rods and plays an irreplaceable role in the gas phase detection.
Our QToF mass spectrometers Standard Designs and Customised Quadrupole Design,
offers our customers a high degree of flexibility in the design to suit specific technical and commercial needs.
The standard quadrupole can be adapted to include additional options such as pre and post filters, mounting saddles and electrical connections.

The standard quadrupole can be adapted to include additional options such as pre and post filters, mounting saddles and electrical connections.
The 3W machine standard quadrupole has proven to be a very cost effective solution for use in the proofing and prototyping stages of our customers’ designs and for use in lower volume instrument production. All of our quadrupoles are supplied cleaned, assembled in our laminar flow cleanroom, with mechanical test results, showing the maximum measured deviation between opposing rods.
Sealing parts are usually made of high-quality seals, sealants or welding.
The selected material should have good vacuum compatibility, low outgassing rate, can withstand the pressure difference in the vacuum environment, and have certain corrosion resistance and high temperature resistance.
The internal and external surface area of the cavity need to be treated in order to reduce the ability of surface adsorption of gas and impurities, reduce the outgassing rate and improve the stability of vacuum.

The design of vacuum chamber needs to consider many factors, such as sealing, strength, thermal stability against short circuit, surface roughness and internal cleanliness. They vary in shape and size, depending on the specific application requirements, and may be cylindrical, square, or other special shapes.
On the surface of the chamber, there may be various interfaces and ports for connecting vacuum pumps, measuring instruments, pipes, and other related equipment.

In ICP-MS analysis, the sample is usually introduced into the argon stream as an aerosol of aqueous solution and then into the central region of argon isoliths excited by radio frequency energy at atmospheric pressure. The high temperature of the plasma causes desolvation, vaporization dissociation and ionization of the sample. Part of the plasma enters the vacuum system through different pressure regions, and the sampling cone is responsible for effectively transmitting the ions in the plasma to the mass spectrum section.
Sampling cones are usually made of metals such as Ni, Al, Cu, Pt, among which Ni cones are most used.
Sampling cone we can not only do a single piece can also do components

Sampling cones are usually made of metals such as Ni, Al, Cu, Pt, among which Ni cones are most used. In order to meet the requirements of the ICP-MS ion collection interface, the sampling cone needs to have several characteristics:
- Maximization of the passage of generated ions;
- maintaining the ionic integrity of the sample;
- Keep the yields of oxides and secondary ions as low as possible;
- make the secondary discharge of the plasma as small as possible;
- Resistance to blockage;
