PFA (perfluoroalkoxy resin) atomizer is a high-performance atomization device with chemical corrosion resistance, high temperature resistance, and low adsorption as its core characteristics. It is widely used in trace analysis fields such as inductively coupled plasma mass spectrometry (ICP-MS) and inductively coupled plasma emission spectroscopy (ICP-OES), especially suitable for atomization needs of strong acids, strong bases, and organic solvents.
1、 Core Features
Chemical corrosion resistance
PFA material has excellent resistance to strong acids and bases such as hydrochloric acid, nitric acid, hydrofluoric acid (HF), and organic solvents. It can stably transport high-purity chemicals for a long time, avoiding performance degradation or data distortion caused by corrosion. For example, the Savillex PFA atomizer in the United States is clearly labeled as suitable for HF atomization and offers multiple models to adapt to brands such as Agilent, CETAC, ESI ICP-MS, and automatic injection systems.
heat resistance
The working temperature range covers -80 ° C to+260 ° C, supporting high-temperature processes such as CVD/PVD, while meeting stable operation requirements in low-temperature environments (such as -40 ° C to+55 ° C).
Low adhesion and high precision
PFA material has a smooth surface, reducing sample residue and ensuring detection accuracy. For example, the PerkinElmer N0777720 PFA microfluidic atomizer has a detection limit as low as 0.1 ppb for trace arsenic in groundwater; Semiconductor manufacturers can operate continuously for over 2000 hours without corrosion when transporting ultra pure hydrofluoric acid during wafer cleaning processes.
Micro traffic design
The sample extraction rate can be as low as 0.05-0.6 mL/min (such as PerkinElmer models) or 20-200 μ L/min (such as Agilent self-priming PFA atomizers), suitable for trace analysis, while improving signal stability through the generation of extremely small particle aerosols (atomization efficiency>98%).
Modularity and compatibility
Integrated EzyLok connector, integrated capillary tube, and optional automatic sampler probe, compatible with PerkinElmer's full range of ICP and third-party equipment (such as Thermo Scientific, Agilent, Nu instruments, etc.). For example, the Savillex C-Flow atomizer offers two flow rate versions, 50 μ L/min and 200 μ L/min, and supports pump injection or self suction sampling.
