AutoTitrator
This module gives the Nicomp 380/ZLS the ability to automatically make
multiple measurements on the same sample over a series of different
pH's or ionic concentrations. This allows iso-electric points to be
determined.
Phase Analysis Light Scattering (PALS)
The use of Phase Analysis (instead of the standard amplitude analysis)
allows for the more accurate and precise measurement of small Doppler
shifts. This means that zeta potential measurements can be made in high
ionic strength or high dielectric environments (like alcohols and organic
solvents).
Autodilution
This patented feature eliminates the need for manual dilution of concentrated
samples. Autodilution makes particle size analysis quick and easy, with
no training required. Results are highly reproducible, especially useful
for multiple users.
High Powered Lasers/APD Detector
The Nicomp 380 can be equipped with various high-powered lasers as well
as a high-gain Avalanche Photodiode Detector to increase signal-to-noise
and sensitivity in systems that do not scatter light well. Proteins,
micelles, other macromolecular-based systems, and nanoparticles are
often dilute (1 mg/ml or less) and are made of atoms that do not scatter
light well. The high-powered laser options offer the ability to obtain
accurate results in a short period of time.
Multiangle
Particles larger than 200 nm do not scatter light isotropically in all
directions. It is possible to make DLS measurements more sensitive to
certain sized particles by changing the angle of detection. The Nicomp
380 can be equipped with a mini-goniometer that moves the optical fiber
between 12 and 150 degrees by 1-degree increments.
Autosampler
Offers the ability to run samples in batches unattended. Adding the
27-sample Autosampler module can increase the efficiency of data production
and allows users to get more out of the Nicomp.
