[0002] The atomizing nozzle is one of the most important components of the evaporative light scattering detector. Its function is to atomize the eluent flowing out of the liquid chromatography system at the front end of the ELSD to form an aerosol. The particle size, uniformity, and injection direction and speed of the aerosol are all determined by the nozzle. The slight vibration of the needle in the nozzle will cause noise in the detector at the back end of the instrument.

[0003] In the prior art, the application number is CN202123180738.5, and the application name is an atomizing nozzle for an evaporative light scattering detector. The technical scheme recorded therein includes a nozzle body that is roughly cylindrical, an inner cylinder is embedded in the nozzle body, and an annular airflow gap with one end closed is provided between the nozzle body and the inner cylinder. An air inlet pipe opening for passing high-pressure air or high-pressure nitrogen and communicating with the airflow gap is provided on the side wall at one end of the nozzle body away from the airflow outlet, and a joint is threadedly embedded in the inner cylinder, an atomizing drainage tube is provided on the joint, the atomizing drainage tube extends to the end of the inner cylinder, an ultrasonic transducer is provided on the joint, a gap of 0.3-0.5 mm is left between the atomizing drainage tube and the ultrasonic transducer, and the atomizing drainage tube is directly opposite to the small hole in the middle of the ultrasonic transducer.
