<주장비>
1. Nano Particle Size Analyzer
1-1. Feature
1) Simplified sample preparation with little or no dilution for size mearsurement (<40wt%)
2) Comprehensinve range of low volume cells (12ul - 1ml)
3) Non-invasive back scatter technology built-in for increaserd sensitivity and accuracy
of nano particle < 1nm in size and <1000Da in Molecular weight

1-2. Measurement Method
1) Backscatter (more than 173 degree) preferred for concentrated dispersions.
2) Mixed mode measurement(FFR + SFR) method and Electrophoretic mobility measurement
for the Zeta-potential measurement.
3) Organic solvent sample can be measured by Smoluchowski formula and Huckel formula in
analysis software
4) When we measure a particle size, we can make sure Aggregation and dispersion which be
known to quality of particle through measurement quality report and correlogram.
5) Premium system for the ultimate in colloid and protein characterization and also
Microrheological characterization available (optional)
