Micromeritics to Showcase a Variety of New Instruments at Pittcon 2010

Published on February 17, 2010 at 8:01 PM

Pittcon, one of the world's premier annual conferences devoted to laboratory science and instrumentation, takes place from February 28 through March 5, 2010, at the Orange County Convention Center in Orlando, FL.

Micromeritics, located in Booth 1721, will introduce significant developments in material characterization instrumentation. This year's exhibition presents a great opportunity to get a look at a variety of new instruments and instrument options available from Micromeritics, as well as the opportunity to speak personally with the company's technical and sales representatives.

The new generation Saturn DigiSizer® II High-Definition Digital Particle Size Analyzer utilizes a state-of-the-art CCD detector containing over three million detector elements, Mie theory, and unique design and data reduction features to provide an extremely high level of resolution and sensitivity not available in other laser particle sizing systems. The Saturn DigiSizer II analyzes and measures particles over a range of 40 nanometers to 2.5 millimeters. Features such as fully automated sampling and low-volume sample handling units and a complete system for circulating the dispersing liquid/sample mixture through the cell and reservoir make the Saturn DigiSizer ideal for a wide range of production, research, and quality control applications.

The MicroStar Residual Gas Analyzer features a quadrupole mass spectrometer that complements the Micromeritics AutoChem 2910, 2920, and 2950 dynamic chemisorption analyzers and is ideally suited for pulse chemisorption studies and temperature-programmed reactions. It allows the user to follow the evolution of residual gases from the AutoChem and use the resulting data to determine reaction kinetics, product selectivity, and reaction yields; all of which are vital components of a successful catalyst development program. Unlike traditional temperature-programmed desorption or reduction experiments where only one active gas is monitored, the MicroStar provides continuous monitoring of reaction products (up to 128 different masses).

Micromeritics' ASAP 2020 is now available with new vapor and water vapor options. This added versatility provides researchers and formulators the capability to characterize the surface area and porosity of materials both before and after exposure to vapors or moisture. The ASAP 2020 vapor option allows characterization of large samples including tablets, pellets, granulated food, powders, and desiccant packs and is compatible with a wide range of vapors including benzene, toluene, xylene, ethers, aldehydes, alcohols, and amines. The ASAP 2020 water vapor option is an ideal tool for performing a detailed characterization of pharmaceuticals, food, cosmetics, and many other materials that sorb moisture. The moisture adsorption isotherm may be used to understand the water activity of a material which may influence chemical stability, microbial activity, flow properties, compaction, hardness, and dissolution rates. Unlike traditional gravimetric moisture analysis, the ASAP 2020 water vapor option allows the user to characterize large samples.

Micromeritics' ASAP 2420 enhanced micropore option extends the low-pressure measurement capabilities of the instrument and allows enhanced performance for characterizing microporous materials using nitrogen, argon, carbon dioxide, hydrogen, and other fixed gases. The ASAP 2420 design allows for high-performance/high sample throughput with six independently operated ports for adsorption analysis and a fully automated sample preparation module with twelve independently controlled stations. The multiport capabilities of the ASAP 2420 provide an ideal platform for research and quality control laboratories requiring high-throughput material characterization including: BET surface area, pore volume distributions, pore area distributions, micropore analysis, and NLDFT modeling of adsorption isotherms.

Since the formation of Particulate Systems and its acquisition of the Particle Insight Dynamic Image Analyzer, this Micromeritics brand has added a number of new products and announced a strategic collaboration with Surface Measurement Systems Limited.

The HPVA-100 High-Pressure Volumetric Analyzer uses the static volumetric method to measure high-pressure adsorption isotherms with hydrogen, methane, carbon dioxide, and other gases. Applications include catalysts, zeolites, activated carbons, carbon nanotubes, hydrides, and metal-organic frameworks. The operating pressure of the HPVA ranges from high vacuum to 200 bars. Sample temperatures during analysis can range from cryogenic to 500 oC.

The Magnetic Analyzer MA-1040 detects minute quantities of iron in a wide range of materials including high-purity glass used in fiber optics to plastics used in wiring insulation. With sensitivity as low as 0.00001% magnetic content, the MA-1040 can also be used to detect low magnetic iron levels in food, precious gems, pharmaceuticals, and many other materials.

The collaboration of Particulate Systems with Surface Measurement Systems Limited gives distribution rights to Particulate Systems for key Surface Measurement Systems products in selected regions of the world. These products include the DVS Dynamic Vapor Sorption Systems, which utilize dynamic gas flow and the gravimetric technique to produce high-resolution adsorption and desorption isotherms of water and organic vapors on solid materials.
