원리와 특징

Features

 ㆍIt measures particle size and zeta potential in a wide concentration range from dilute to a concentrated solution (~40%) 

 ㆍMulti-angle mesurement enables measurement of particle size distrubution with high resolution

 ㆍZeta potential of the flat sample can be measured under a hypersaline environment

 ㆍParticle concentration can be measured using the static light scattering method

 ㆍMicroheology measurements is possible by the dynamic light scattering method

 ㆍIt is possible to evaluate the network structure and non-uniformity of the gel by measuring multiple points of the gel sample

 ㆍContinuous measurement of particle size and zeta potential is possible with a standard flow cell

 ㆍIt has a wide temperature range between 0 and 90℃

 ㆍDegeneartion, phase transition temperature analysis of proteins, etc. are possible by the temperature gradient funtion

 ㆍIt provides highly precise zeta potential measurment results by measuring the electro-osmosis flow and plot analysis in the cell
