Interphex 2011 will be held at New York's Jacob K. Javits Convention Center
on March 29 - 31, 2011. More than 650 suppliers and 1,000 product lines will
fill the show floor's four exhibit zones. In addition, there will be more than
thirty technical sessions, roundtables, live in-depth interviews, a new meeting
service, and a series of special events.
Micromeritics, located in Booth 1230, will not only display a
variety of its own products, but also material characterization instrumentation
represented by its Particulate Systems brand. With the addition of this brand,
Micromeritics currently offers one of broadest ranges of particle
characterization instruments and services on the market.
Micromeritics and Particulate Systems offer a number of instruments that each
utilize a different method to determine particle size distribution of
pharmaceutical powders, including one for characterizing particle shape. Methods
include Static Laser Light Scattering, Dynamic Laser Light Scattering,
Electrical Sensing Zone, and Dynamic Image Analysis.
Utilizing a state-of-the-art CCD detector containing over three million
detector elements, Mie theory, and unique design and data reduction features,
the Saturn DigiSizer II High-Definition Digital Particle Size Analyzer measures
particle size in a range of 40 nanometers to 2.5 millimeters. It provides an
extremely high level of resolution and sensitivity not available in other laser
particle sizing systems. The Elzone II 5390 Particle Size Analyzer determines
the size, number, concentration, and mass of a wide variety of organic and
inorganic materials. Unlike other measurement techniques, the electrical sensing
zone method (Coulter Principle) is capable of accurately sizing samples of
varying optical properties, densities, colors, and shapes. The Elzone determines
particle size in a range suitable for a wide variety of industrial and
biological specimens down to 0.4 micrometer.
Particulate Systems Particle Insight Dynamic Image Analyzer is ideal for
applications where the shape, not just the diameter, of raw materials is
critical to the performance of the final product. The Particle Insight offers up
to 28 different shape parameters analyzed in real-time in either aqueous or
organic solvent suspensions. The system measures particles in a range from 3
micrometers up to 300 micrometers in its standard configuration. With its
temperature stabilization feature, the Cordouan VASCO DLS Particle Size
Analyzers are unique dynamic light scattering (DLS) nanosizing instruments
capable of measuring particle size in a range from 6 micrometers to 1 nanometer.
Its optical configuration design provides superior detection efficiency for
opaque sample, decreases the instrument sensitivity to 'multiple scattering
artifact', and strongly reduces the laser thermal effect allowing very accurate
measurements even in concentrated and dark dispersions.
Surface area and porosity are important physical properties that influence
the quality and utility of many pharmaceutical materials and products. From
increasing the speed and efficiency of a routine quality control analysis to
providing the accuracy, resolution, and data reduction for exacting research
requirements, Micromeritics offers an instrument to fit the application. The
TriStar II 3020 Surface Area and Porosity System is a fully automated,
three-station instrument capable of increasing the speed and efficiency of
quality control analyses, with the accuracy, resolution, and data reduction to
meet most research requirements. The instrument includes a dedicated saturation
pressure port and three analysis ports that operate simultaneously and
independently of one another. A krypton option allows measurements in the very
low surface area range.
Gas pycnometry is a common analytical technique that uses a gas displacement
method to measure volume accurately. These volume measurements can be used to
calculate absolute density which is an important physical characteristic to many
pharmaceutical applications. Micromertics AccuPyc II 1340 Gas Displacement
Pycnometry System is a fast, fully automatic analysis system that provides
high-speed, high-precision volume measurements and density calculations. The
AccuPyc determines absolute density of powders, solids, and slurries having
volumes from 0.01 to 350 cm3 with superior accuracy. For those who require high
throughput, an integrated control and analysis module can run up to five
additional external analysis modules. Each module can have a different size
sample chamber (1 cm3, 10 cm3, 100 cm3, 350 cm3) providing even more
versatility. In addition, obtaining skeletal volume measurements using the
AccuPyc combined with envelope volume from Micromeritics' GeoPyc 1360 allows
the user an alternative low-cost method to quickly determine total pore volume
and percent porosity in a dry environment. This information has proven to be
useful in controlling the mechanical properties of pharmaceutical material,
compression force settings on the roller compactor, and subsequent tablet press
settings.
