Principles of measurement
Particle Size Measurement: Kinetic Light Scattering
Molecular weight measurement: Debye graph method (static scattered light intensity)
Measuring range
Particle Size: 0.3 nm to 10 μm
Molecular Weight: 1000 to 2 x 107 Da (Debye Graph)
540 to 2 x 107 Da (MHS Equation)*1: Maximum sample concentration 40 wt%*2
Particle size measurement accuracy
Measurement accuracy is 2% for NIST polystyrene rubber spheres (excluding variation in standard beads)
Measure angle: 90° and 173° (automatic or manual selection)
Measuring cell: Cuvettes
Measurement time
Approx. 2 minutes under normal conditions
(From the start of the measurement to the display of the particle measurement result)
Required sample volume: Minimum sample volume 12 μL*3 to 1000 μL (varies depending on cell material)
Usable liquid: Water, ethanol, organic solvents
