Is atomic fluorescence spectrometer harmful to human body?

As long as the operation is standardized, the instrument is harmless to people. If it is harmful, you should generally pay attention to the following points: 1. Pay attention to the safety of electricity use. Before using any instrument, check whether the circuit connection is correct and whether there is any leakage to prevent electric shock. 2. When preparing samples, pay attention to the use and preparation specifications of chemicals and safe operation specifications. Toxic or volatile samples should be prepared in a ventilated kitchen, and operators should wear corresponding protective masks, gloves and laboratory clothes. 3. After the sample is put in, close the cover of the sample bin to prevent the incident light from exposing the sample bin. (In fact, the incident light is generally ultraviolet-visible light emitted by xenon lamps, and only the ultraviolet band is harmful to people. ) 4. After the sample is tested, the sample should be recycled specially, and it is not allowed to be poured into the pool at will, so as not to pollute the environment and cause harm to the health of yourself and others.
