Jena mass spectrometer from GermanySupporting atomizerThe core function is to convert liquid samples into uniform aerosols, which can then enter the ion source to complete ionization. It is a key component of the mass spectrometer sample introduction system, and its working principle can be divided into three core steps: power supply, atomization process, and aerosol screening

Power supply: The carrier gas driven atomizer will be connected to high-purity carrier gas (commonly argon gas), which will be sprayed at a set flow rate from the atomizer nozzle at high speed. High speed airflow will create a negative pressure zone around the nozzle, utilizing the Venturi effect to continuously suck liquid samples from the storage device into the atomizer.

Atomization process: The liquid sample and high-speed carrier gas are fully mixed and collided inside the atomizer, and the originally large volume droplets are sheared and broken into micrometer sized small droplets, forming the initial aerosol. The precision nozzle design of the Jena atomizer in Germany ensures the uniformity of droplet breakage and reduces the residue of large droplets.

Aerosol screening: The initial aerosol for graded purification will pass through the built-in splitter or filter structure of the atomizer, and larger droplets will be intercepted and refluxed. Only uniformly sized fine aerosol particles will enter the ion source of the mass spectrometer with the carrier gas, providing a stable sample basis for subsequent ionization and detection.

Overall, the atomizer achieves efficient conversion of liquid samples to aerosols through a continuous process of negative pressure sampling with carrier gas, high-speed impact fragmentation, and graded screening, ensuring the sensitivity and repeatability of mass spectrometry detection.
