SESSION 1: 9:00 AM TO 10:30 AM - BIRCH ROOM
"The Particle Size Paradox"

Jack G. Saad, Associate Scientist, Micromeritics Instrument Corp.
Particle size is an important piece of information for research
and development, quality control, and quality assurance as
well as understanding the small physical details in a milling
or powder compaction process. These details can contribute
to potential desired and undesired products. With recent
technological advances, particles are now measured using
various analytical techniques and instrumentation. Different
analytical techniques seldom provide the same value for
particle size. The “paradox” of particle sizing is that all the
different values are the correct value. A survey of six different
particle size techniques are discussed and compared.
This talk will explore:
• Dynamic image analysis
• Sedimentation
• Static light-scattering (laser diffraction)
• Electric sensing zone
• Air permeability
• Dynamic light scattering (DLS)

SESSION 2: 11:00 AM TO 11:45 AM - BIRCH ROOM
"Understanding Size by DLS & Zeta Potential Applications"

Jack Saad, Associate Scientist, Micromeritics Instrument Corp.
One of the most common techniques used today is Dynamic
Light Scattering (DLS) to determine and monitor the size of
nanoparticles, proteins, emulsions, and other sub-micron
materials. DLS instruments are typically coupled with the
ability to determine zeta potential by electrophoretic light
scattering. It is often the case where DLS and zeta potential
is used by a supplier of material, a purchaser of material, or a
partner company and now your company or lab is required
to use this technology without an understanding of “why.”
In addition, to “why,” many researchers consider size to
be size and have trouble explaining why size of particles
determined by SEM or TEM do not match size by DLS.
This talk will explore:
• How size is determined by DLS and why is it
different from size by SEM and TEM.
• What zeta potential is and how to use the data,
• The relationship between size and zeta potential

SESSION 3: 1:00 PM TO 2:00 PM - BIRCH ROOM
"External Morphology and Elemental"

Characterization of Catalyst by Desktop SEM-EDS
Jeff Sherman, PhD, Vice President, Micromeritics Instrument Corp.
The characterization of surface topography has become
increasingly important in catalyst characterization and
through the increasing resolution and simplification
of microscopic devices, such as SEM, (scanning
electron microscopy), the move from sophisticated
and dedicated operations to a benchtop, user friendly
device has transformed the industry. The simplification
of SEM into an operator-friendly instrument permits
any user to perform microstructural analysis and
nondestructive testing of catalyst to identify its textural
character and to determine the elemental composition.
This talk will explore:
• Under one-minute catalyst surface topography
investigation with up to 130,000x magnification
• Understanding data from SEM and
how to apply to your research
• Elemental composition examination using SEM-EDS

SESSION 4: 2:15 PM TO 4:00 PM- BIRCH ROOM
"Techniques (and Challenges) for Characterizing Heterogeneous Catalysts"

Jeffrey. Kenvin, Ph.D. Senior Scientist, Micromeritics Instrument Corp.
The classic techniques for characterizing heterogeneous
catalysts can be divided into two categories -- static
(manometric) and dynamic (flow). The earliest technique
and most widely practiced is static adsorption and this
method may be used to explore both physical and
chemical sorption of gases on heterogeneous catalysts.
This talk will explore:
• Reactive techniques for active site characterization
to determine the nature of the catalytic site
• Integration of micro reactor studies with classic temperature
programmed and pulse sorption techniques
• Analyzing catalyst development and process evaluations
in real-time in a microscale environment
