Silica vs. PSL Spheres: Why Silica Particles Are Better in High‑Temperature
In the world of precision metrology and cleanroom validation, accuracy is non-negotiable. For decades, Polystyrene Latex (PSL) spheres have been the industry standard for calibrating particle counters and inspecting wafers. However, as semiconductor and pharmaceutical manufacturing processes push into higher temperature ranges, the limitations of PSL have become apparent. Enter Silica (SiO2) particles. While both […]
