PFA atomizers typically consist of an inner tube, an outer tube, an impact ball cap, a protective sleeve, a flow restriction tube, and optional fittings. Component configurations may be adjusted for different models based on the application scenario. The following is a detailed introduction to its structural composition:
Inner and outer tubes:
The inner tube is used for inhaling the measured solution and is usually designed as a coaxial glass structure to ensure stable transmission of the solution.
The outer tube is connected to compressed air to provide power for atomization and form aerosol particles.
Impact ball cap:
Mounted on the nozzle, it plays a role in impacting and refining aerosol particles, improving atomization efficiency.
Different models of atomizers may be equipped with impact ball caps made of different materials to adapt to different application scenarios.
smart cover:
Usually made of stainless steel, the glass atomizer is fixed to protect it from external damage.
The design of the protective cover needs to be compatible with the atomizer base of the host to ensure stable installation.
Restricted flow liquid pipe:
Made of special polyethylene material, resistant to organic solvent corrosion, ensuring long-term stability during use.
Some models may use a combination structure of stainless steel tubing, silicone tubing, and polyethylene flow restriction tubing to meet different injection requirements.
Connectors and accessories:
Depending on the application scenario, PFA atomizers may be equipped with different types of connectors, such as CTFE connectors, for connecting to automatic samplers.
Some models also offer optional capillaries that users can replace as needed to adjust the injection speed.
