Particle sizer has extended temp range
particle characterisation systems, which enable scientists to
measure particle size at temperatures of up to 120C, extending the
range from the standard 90C.
Measurements at high temperatures are especially applicable to applications performed in the laboratory as the stability, chemical reactivity, opacity, flowability are affected by the size and characteristics of the particles within them.
Measuring the size of a polymer dispersion at close to the melting point of the polymer can provide important information about phase, shape or conformation changes.This can be used in research for characterising the polymer dispersion and designing manufacturing processes for polymers with melting points above 90C.
Particle size analysis using dynamic light scattering requires the sample be a liquid, so the system must have the capability of measuring at temperatures above this melting point.
The Malvern Zetasizer Nano series uses patented technologies to deliver particle size measurement in the range 0.6 to 6000nm and measure the zeta potential of particles from 5nm to 10mm in diameter.
The series is suitable for the measurement of highly dilute proteins and polymers as well as the ability to analyse emulsions at high concentrations. All measurement routines are highly automated and an optional unit, the MPT-2 autotitrator, is available to simplify the systematic study of size and zeta potential as a function of variables such as pH, conductivity or additive concentration.
