Particle Characterization
Greetings from your friends at HORIBA Instruments!
Our latest edition welcomes you to attend two webinars and download a new application note on gold nanoparticles, a new technical note on the LB-550 Dynamic Light Scattering technique, and two new test methods for measuring LUDOX silica on the LA-950 and LB-550. We're also announcing an analyzer trade-in program so you can get a discount for your older analyzers. Like the new trade-in program, our Academic Stimulus and Lunch and Learn initiatives are active through the end of 2009!
Webinar on Nanotechnology
Please join us for our web-based seminar (or Webinar) Tuesday, July 21 at 1:30 PM Eastern (10:30 AM Pacific) on nanotechnology and nanoparticles.
While the term "nanotechnology" has evolved in recent years, a major branch of this research is centered on particles in the range of 1 -100 nm where particles exhibit novel properties due to their size. Topics covered include:
- Defining the size scales involved
- Characterization techniques
- Sample preparation
- Nanoparticle applications
Attending the Webinar is easy and free of charge. We will be glad to help you understand how to attend.

Webinar on Sampling and Dispersion
Please join us for our web-based seminar (or Webinar) Tuesday, July 7 at 1:30 PM Eastern (10:30 AM Pacific) on the important role of sampling and dispersion when using laser diffraction. This is another lecture taken from the diffraction customer training courses, or "boot camps". Topics covered include:
- Sources of error in particle size measurement
- Good, better, and best sampling techniques
- Surfactant selection
- Use of ultrasound
Attending this Webinar is free of charge and registration is simple and quick.

Trade-In and Move-Up to the Latest Particle Characterization Technology!
Beginning July 1, HORIBA will offer the best possible trade-in value for your old instrumentation! This program includes any laser diffraction (LA series), dynamic light scattering (LB series), image analysis (CAMSIZER, PSA300), acoustic attenuation (DT series), electroacoustic spectroscopy (DT series) or BET surface area analyzers (SA series) - even non-HORIBA instruments. You could save up to 40% off any new system. Replacing an older analyzer with the newest technology available makes the particle analysis task easier and faster, while also providing higher quality data. A variety of financing options are available in combination with any trade-in discount to help you obtain the state of the art that much more easily.
Contact us today to get more details on upgrading to the latest in particle characterization instrumentation.
Particle Size Analysis of Gold Nanoparticles
Scientific interest in well dispersed suspensions of colloidal gold (or nanoparticles) can be traced back to ancient times. Original uses of colloidal gold included potions, stained glass and other artistic expressions. Current research using gold dispersions remains quite active and controlling the size and morphology of the particles is critical.
Recently, the National Institute of Standards and Technology (NIST) has developed Reference Materials (RMs) of gold nanoparticles that are nominally 10, 30 and 60 nm. This application note describes a procedure and shows results from a study analyzing the NIST RM samples.

The LB-550 DLS Technique
The LB-550 Dynamic Light Scattering (DLS) System measures particle size from 1nm to 6 um at concentrations up to 40%. All DLS systems measure light scattering effects arising from the Brownian motion of particles in suspension. Unlike systems using correlators, the LB-550 uses a fast Fourier transform to create a power spectrum from the light scattering fluctuations. The power spectrum is then used to create the particle size distribution. This technical note explains the underlying principles used by the LB-550.

Analytical Test Methods for LUDOX™ Silica
Our recent Technical Note, TN158 Particle Size and Charge Reference Material (You need to be logged in), triggered several inquiries to our technical support team on how to best measure this sample. In response, we have created two new Analytical Test Methods (ATMs) for measuring LUDOX™ silica on both the LB-550 and LA-950 systems.
Analytical Test Method ATM107 Measuring LUDOX™ on the LA-950 (You need to be logged in).
Analytical Test Method ATM108 Measuring LUDOX™ on the LB-550(You need to be logged in).
The HORIBA PSA "Academic Stimulus" Program Meeting the Needs of Today's Scholars
For New College/University Customers: Through the end of 2009, the HORIBA PSA group will guarantee the best possible discount - up to 12% - to universities and academic centers in the United States. Additionally, a free second year warranty will be included.
For our Existing College/University Customers: We invite you and your advisor/grad students to submit an abstract for an application note showing data from a HORIBA PSA system. If your submission is approved, we will post the completed document on our global website and you'll receive $500 and an iPod Nano to show our thanks.

The HORIBA "Lunch and Learn" Seminar Series
Our new "Lunch and Learn" series is designed to bring you valuable technical advice in a format that is fun, convenient and informative. An expert from our Particle Size Analysis (PSA) team will present a one hour seminar during your lunch break while you enjoy lunch courtesy of HORIBA.
All you need to do is host the event in a conference room and invite any interested scientists. The topics offered in the seminar series include:
- A Structured Approach to Particle Size Method Development
- Size Analysis of Nano-Particles
- Getting the Most From Your Laser Diffraction Particle Size Analyzer
- Characterization of Geological Samples and Sediment Particle
- Characterization in the Pharmaceutical Industry
If you are interested in a Lunch and Learn seminar at your facility, click here to contact us directly.
HORIBA's Donation to Penn State has Arrived!
The Center for Innovative Sintered Products (CISP) at Penn State has recently received a HORIBA LA-950 Particle Size Analyzer, which enables students to test metals, ceramics, pharmaceuticals and other powders in a variety of fluids.
The Researchers at CISP now have the most advanced laser diffration particle size analyzer for their research. The LA-950 measures particles in the 10 nanometer range all the way up to 3.0 mm.
