Step 1: Assemble the die and install the sample.

Step 1: Assemble the die according to the operation diagram. Place the boric acid-mixed sample powder into the die cavity.

Step 2: Pressurize the die in a hydraulic press.

Step 2: Position the assembled die in the center of your laboratory press. Apply the required pressure based on your sample and desired pellet density.

Step 3: After pressing, reconfigure the die for demolding (as per the release diagram). Carefully eject the formed pellet from the die sleeve, typically using the press or a dedicated ejector.

Step 4: Gently retrieve the finished pellet. Your sample is now optimally prepared for XRF analysis.

The press allows for precise adjustment of pressure and speed, ensuring reproducible results and efficient batch production.

How Does A KBr Pellet Press Work?

The KBr pellet method is based on the fact that potassium bromide becomes plastic under high pressure and forms a transparent matrix when compressed. This matrix allows infrared light to pass through, making it ideal for IR spectroscopy. The sample is mixed with KBr powder in a specific ratio (typically 1:100 to 1:200, sample to KBr) to ensure even distribution and minimal blockage of IR light.

What Materials Are Commonly Used To Make Press Molds?

Press molds are typically made from durable materials such as Cr12MoV alloy steel, carbide (e.g., YT15), and hardened steel. These materials are chosen for their high hardness, durability, and resistance to wear and high pressure, ensuring long-lasting performance in laboratory environments.
