The new SZ-100 dynamic light scattering (DLS) system measures particle size, zeta potential, molecular weight, and second virial coefficient all in one instrument. This is the most advanced DLS system available with the ability to measure particle size at 90 and backscatter - at both the cell center for low concentration samples and at the cell wall for high concentration. The system automatically selects the optimun optical configuration based on scattering intensity. The unique disposable zeta potential cells feature carbon coated electrodes, extending the number of measurements possible in each cell well beyond that of gold or palladium electrodes.

Considerable research has been conducted exploring the use of nanoparticles composed of biopolymers as a drug delivery vehicle. Since the design goal for nanoparticles is in the range of 100 nm, much of the particle size analysis in this field has been done using dynamic light scattering (DLS) but laser diffraction is also capable of measuring many of these samples as well. This application note describes two experiments where laser diffraction proved capable of determining both the base biopolymer nanoparticles and also larger particles outside of the range of DLS.

Polystyrene latex (PSL) beads are popular size standards for particle analysis since they are well characterized, readily available, and relatively inexpensive. Thus, they are often used for instrument qualification.

This application note (AN197) shows the ability of the new HORIBA SZ-100 to characterize these samples. Click here to visit the Download Center where you can read this and other Application Notes.

HORIBA Scientific will be attending the fall ACS meeting this year in Denver, Colorado August 29th through September 1st. We will be showing our newest particle size analyzer the SZ-100 and will have technology specialists on hand to discuss particle size, raman and fluorescence spectroscopy.

You can find us at booth #1612. Jeff Bodycomb and Eunah Lee will be presenting information on high speed physical and chemical characterization of mixed particulates using static image analysis and Raman microscopy on Thursday, September 1st at 9 AM in room 707.
