SprayIt is a double-layer structure, with the outer tube serving as the carrier gas passage and the inner tube as the sample tube. The inner and outer tubes are positioned, and the carrier flow enters the outer tube, forming a high-speed airflow and negative pressure at the nozzle, guiding the sample solution to spray out and form a sample aerosol. Normally, the design and application range of ICP atomizers is for samples with a solid solubility of 1%. ICP atomizers have outstanding advantages such as high sensitivity and good accuracy, and can be applied to various organic and inorganic samples. The use efficiency of ICP atomizer, combined with the application of swirl chamber, can achieve excellent detection limits for conventional low salt samples. Similarly, the ICP atomizer also has a high salt design, which can adapt to salt content up to 15%. But pay attention to cleaning, otherwise blockage may occur. For high salt samples, * is a D-type atomizer, which should be equipped with a double-layer mist chamber and an A-type swirl mist chamber, connected to the atomizer. Mainly adjust the depth and tightness of the atomizer inserted into the swirl chamber. Note: The spray at the top of the atomizer requires the atomizer to be fully inserted to make the seal ring tight without air leakage.
Maintenance of spray
After using the atomizer for a period of time, some sediment may accumulate or blockage may occur. In order to make the analysis data more reliable, the atomization effect *. Usually, appropriate cleaning solvents can be used to soak and dissolve the sediment on the atomizer, eliminating its impact, but do not use ultrasonic cleaners.
Fault handling and maintenance
1. Blow gas in the opposite direction from the nozzle, or use a syringe to fill water and inject it in the opposite direction to ensure smooth flow.
2. Drip a drop of concentrated hydrofluoric acid from the nozzle into the inner tube, rinse with water after about 5 seconds, and then blow back with gas
