Micromeritics to Showcase New Instruments at the 2006 Pittsburgh Conference - 3/09/2006
The Elzone II 5390 Particle Size Analyzer, utilizes the electrical sensing zone method to size samples without being affected by optical properties, densities, colors, and shapes. The Elzone quickly and accurately determines the size, number, concentration, and mass of a wide variety of organic and inorganic materials. Easy-to-use automated features include: start-up, run, and shut-down routines; blockage detection and clearing; flushing/rinsing; and calibration. The Elzone determines particle size in a range suitable for a wide variety of industrial, biological, and geological specimens. A high level of accuracy, resolution, speed, ease-of-use, and a compact size make the Elzone equally suitable for industry, quality control, and research and development laboratories. The Gemini VI Surface Area Analyzer boasts improvements that benefit those applications requiring extended analysis time and high stability. Upgrades from the Gemini V include a larger cabinet which allows for longer sample tubes and a larger, taller Dewar. The new larger Dewar not only extends the life of the cryogen bath, but also provides a very stable thermal environment in which to measure the isotherm. The results are improved repeatability from one sample to the next and sufficient analysis time for a complete adsorption - desorption isotherm. Another improvement is the capability to monitor continuously the saturation vapor pressure (P0) of the adsorptive using a dedicated P0 tube and transducer. The result is a more meticulously determined relative pressure. These improvements combined with features such as automatically generated or user-defined pressure tables with user-selected endpoints, free-space determination and correction options, and a variety of reports make the Gemini VI a valuable tool for the determination of surface area and pore size distribution. The ASAP 2420 Accelerated Surface Area and Porosimetry System introduced in January will be featured at Pittcon as well. This powerful instrument is specifically designed for laboratories where high sample throughput is a strategic priority. With six independently operated preparation and analysis ports, a new analysis can begin as soon as another is finished. This provides an important advantage over many multiport instruments that require all samples to be prepared or analyzed at the same time. Another key, standard feature of the ASAP 2420 is a programmable and fully automated sample preparation module with twelve independently operated ports. Samples may be added or removed from degas ports without disturbing the treatment of other samples undergoing preparation or analysis. Accurate extended analysis is accomplished with larger Dewars and Isothermal jackets. In addition to typical reports such as BET and Langmuir surface area, t-Plot, and BJH pore size distribution, the ASAP 2420 also features the STSA thickness curve, and DFT (NLDFT)pore size and surface energy reports. High throughput, reliability, versatility, and high quality data describe the new ASAP 2420. The new ElectroPrep™ 053 provides a constant supply of filtered electrolyte for the Elzone II 5390. The ElectroPrep recirculates electrolyte through a filter cartridge that retains particles greater than 0.1 to 0.2 micrometers in diameter. In typical usage, one preparation of electrolyte may last for several months.
