Comparison of Pressing Method and Fused Glass Disc Method
Processing Method | Pressing Method | Fused Glass Disc Method |
Sample | All powders | Limited to oxide powders |
Quantitative Accuracy | Poor | Very good |
Preparation Time | 1 minute | 10~20 minutes |
Price | Low price | High price |
Comprehensive evaluation:
(1) The pressing method is often used for occasions with few varieties and low requirements for analytical errors, while the glass fusion method is often used for occasions with high requirements for errors. Because the fusion method can overcome the influence of particle size effect and mineral effect.
(2) In most cases, the powder is composed of irregular fine crystals. In the glass fusion method, the crystals disappear and become a microscopically uniform sample, thus improving the accuracy and meeting the error requirements of the analysis standard.
