Micromeritics to Showcase a Variety of New Instruments at Pittcon 2008 - 2/22/2008
Pittcon is one of the world’s premier annual conferences devoted to laboratory science and instrumentation. This year, Pittcon takes place March 2 through March 7 at the Ernest N. Morial Convention Center in New Orleans, Louisiana. Micromeritics, located in Booths 2620 and 2621, will be introducing some of the latest developments in particle characterization instrumentation.
This year’s exhibition presents a great opportunity to get a hands-on look at a variety of new instruments available from Micromeritics, as well as the opportunity to speak personally with our technical, sales, and customer support associates.
The TriStar II 3020 Surface Area and Porosity Analyzer is a fully automated, three-station analyzer that can measure surface areas as low as 0.01 m2/g using nitrogen and features a new krypton option that can measure surface areas down to 0.001 m2/g. A dedicated Po port is standard, allowing the user to measure the saturation pressure on a continuous basis. The TriStar II can collect up to 1000 data points. Minute details of the isotherm can be observed and recorded providing high resolution and revealing pore structure details. A 2.75-liter Dewar and extended length sample tubes allow complete adsorption and desorption isotherms to be collected without operator intervention. Enhanced product support features include: video clips, Ethernet communication between the computer and TriStar II, bar code reader capability, built-in electronic test points and diagnostic software, ability to perform remote diagnostics via the internet, and the ability to read and compare historical TriStar and Gemini data to TriStar II data.
The new ASAP 2050 Xtended Pressure Sorption Analyzer is an easy-to-use instrument capable of collecting physisorption data in an elevated-pressure environment. While retaining design elements of Micromeritics’ popular ASAP 2020, the ASAP 2050 analysis manifold is equipped with a pressure transducer capable of operating from vacuum to 10 atmospheres. Custom straight-walled, stainless-steel sample tubes are capable of safely withstanding temperatures and pressures well beyond the system’s specifications. Two independent vacuum systems allow simultaneous preparation of two samples and analysis of another. Sample preparation and analysis can occur concurrently without interruption and without the risk of cross-contamination. The instrument is particularly well suited for fuel cell, hydrogen storage, and pressure swing adsorption research applications.
The AccuPyc II 1340 1-cm3 Gas Displacement Pycnometer is designed for those who typically analyze a very limited amount of sample. The AccuPyc features improvements in design that allow the volume of small amounts of sample to be accurately detected and measured with enhanced reliability to within a fraction of a microliter. A novel manifold design utilizes high-reliability, high-precision valves that seal more securely so that small leaks do not contribute to variability of results. High-compression, minimum-volume seals around the pressure transducer minimize helium storage and leakage. This shortens the time to complete a run cycle and practically eliminates the development of temperature gradients that would otherwise compromise results. The AccuPyc II 1340 1-cm3 also features an ultra-low noise transducer amplifier that results in faster equilibration.
The AutoChem 2950 HP High Pressure Chemical Adsorption Analyzer is an automated catalyst characterization system capable of preparing and analyzing samples at elevated pressures up to 1000 psia and at temperatures from -100 to 1100 oC. The instrument can perform a variety of experiments including pulse chemisorption, BET surface area, temperature-programmed reduction (TPR), desorption (TPD), oxidation (TPO), and reaction analyses. Equipped with all the features of Micromeritics’ AutoChem II 2920, this instrument is suitable for a variety of applications including fuel cell and hydrogen storage research. This micro-reactor, combined with a mass spectrometer, can also be used to determine product yields and catalytic activity under commercially viable conditions.
