KBr, or potassium bromide, is a substance that can pose certain dangers if not handled properly.
5 Key Points to Consider
1. Respiratory Irritation
One of the primary dangers of KBr is its potential to irritate the lungs.
Repeated exposure can lead to bronchitis, characterized by symptoms like cough, phlegm, and shortness of breath.
2. Nervous System Effects
KBr can also impact the nervous system.
This can result in symptoms such as headaches, irritability, impaired thinking, and even personality changes.
3. Hygroscopic Nature
KBr is hygroscopic, meaning it can absorb water from the air.
This can affect its performance in FTIR measurements, so it's crucial to keep it dry.
4. Pellet Production
When making KBr pellets, it's important to heat the anvils and die set beforehand to ensure dryness.
Using dry KBr powder and ensuring all components are at the same temperature helps avoid cloudy or wet pellets.
If keeping the powder dry is challenging, grinding your own powder from random cuttings of KBr can be an alternative.
5. Spectroscopic Grade Purity
The quality of the KBr or halide salt powder used should always be of spectroscopic grade purity.
This ensures optimal results in your measurements.
