Particle Size Meter FAQ
Q: What is the difference between wet and dry measurement modes in a Particle size meter?
A: Wet measurement mode uses liquid dispersion media (typically water or solvents) to separate particles and prevent aggregation, ideal for samples that dissolve or disperse in liquids. Dry measurement mode uses air dispersion for powders that might be affected by liquids or when analyzing airborne particles. Our Particle size meter offers both modes with automatic switching capability.
Q: How often should I calibrate my Particle size meter?
A: We recommend weekly verification checks using standard reference materials and full calibration every 3 months for routine analysis. For GMP environments or critical applications, calibration should be performed monthly. Our instruments include automated calibration verification protocols to simplify this process.
Advanced Analysis Capabilities
| Analysis Type | Description | Applications |
|---|---|---|

Particle Size Meter FAQ (Continued)
Q: Can your Particle size meter handle highly concentrated samples?
A: Yes, our instrument features advanced multiple scattering correction algorithms that can accurately measure samples with up to 40% solids concentration. For opaque samples, we offer a special high-concentration cell attachment that maintains measurement accuracy even in challenging conditions. However, we generally recommend diluting to optimal concentration ranges for most precise results.
