Jul 1，2026
Firstly, pulverize the KBr powder into a 200-mesh size followed by drying at 110°Celsius to remove any bound water molecule. Then uniformly mixing a small amount of your ground sample (0.2% - 1%) with spectroscopy-grade KBr powder. Next, the sample pellet is pulverized and placed into a pellet-forming die. Further, a force of 8 tons is applied under vacuum for several minutes to form a transparent sample pellet.
