The DelsaNano
series from Beckman
Coulter is a new generation of instruments that use photon correlation spectroscopy
(PCS), which determines particle size by measuring the rate of fluctuations
in laser light intensity scattered by particles as they diffuse through a fluid,
for size analysis measurements and/or electrophoretic light scattering (ELS),
which determines electrophoretic movement of charged particles under an applied
electric field from the Doppler shift of scattered light, for zeta potential
determination.
The DelsaNano
series has a broad range of capabilities, including conventional static
and automatic titration measurements for both size and zeta potential distributions
of suspended particles in a wide range of size and concentration. The
DelsaNano can also measure zeta potential of a solid surface or film.
The DelsaNano
series includes the following models:
- DelsaNano
S: Size analysis - 0.6 nm - 7µm
- DelsaNano
C: Size and zeta potential measurement of particles in liquid suspension
or zeta potential measurement of solid surfaces
- DelsaNano
AT: Optional accessory for the automatic titration of sample suspensions.
Titration range from pH 1 to pH 13
