AI Technical Summary

Technical Problem

Existing powder injection devices are prone to powder adsorption onto the inner wall of the cylinder due to static electricity during use, which affects the injection effect.

Method used

A powder injection device was designed, which uses an plexiglass hood with an ion emitter blower mechanism on it. Static electricity is eliminated by an ion fan. The hood is teardrop-shaped to reduce airflow disturbance, and a ventilation pipe is installed on the hood to ensure airflow stability.

Benefits of technology

It effectively eliminates static electricity, reduces powder adsorption, improves the stability and convenience of the sample introduction device, and ensures airflow stability.
