Static light scattering nanoparticle size analyzer SALD-7500nano

opticalfor nanotechnologyfor research

Overview
Delivering 10 times the sensitivity of previous models, this analyzer measures low-concentration or high-light-absorption nanoparticles with improved detection capability. It performs continuous measurements of particle size and size distribution at one-second intervals across a wide range from 7 nm to 800 μm. Options support high-concentration samples (up to 20 wt%) and trace-volume samples (down to 15 μL). Typical application areas include nanotechnology, life sciences, and fine-bubble analysis.

Key capabilities

• Approximately 10× higher sensitivity in the nano range compared with conventional instruments
• Continuous measurement of particle size and distribution at 1 s intervals
• Wide measurement range: 7 nm to 800 μm
• Capability to measure very low concentration samples (below 1 ppm)
• Options for high-concentration samples (up to 20 wt%)
• Trace-sample measurement option down to 15 μL

Highlighted features

• Wide measurement range (7 nm–800 μm) enabling continuous monitoring from primary particles to sub-visible contaminants using a single light source and optical system
• Single detection face continuously captures forward-scattered light up to 60° for seamless coverage of the target particle size range
• Automatic refractive index calculation function reduces manual input and potential user error
