Effective Solutions for Material Characterization

RAPID AND PRECISE SURFACE AREA MEASUREMENTS Surface area and porosity are important physical properties that influence the quality and utility of many materials and products. Therefore, it is critically important that these characteristics be accurately determined and controlled. Likewise, knowledge of surface area and especially porosity often is an important key to understanding the formation, structure, and potential application of many natural materials. High Sample Throughput with Analytical Versatility The Micromeritics® TriStar II Plus is a fully automated surface area and porosity analyzer...

Incremental or fixed dosing routines prevent overshooting pressure points while minimizing analysis time. Three analysis ports operate simultaneously and independently of one another. Three BET surface area measurements can be performed in less than 20 minutes. For additional throughput, four Micromeritics TriStar units can be operated with one computer. The unique analysis manifold is designed for highly-accurate gas management. A dedicated P0 port is standard, allowing the measurement of saturation pressure on a continuous basis. Saturation pressure can be entered manually, measured continuously,...

Additive Manufacturing Surface area is a critical tool in investigating the kinetics of the sintering process and product properties. Particles having rough surfaces or internal porosity will generally exhibit higher specific surface areas. Therefore, surface area indicates the amount of sample surface available to react with other component particles and / or the surrounding environment. Carbon Black The wear lifetime, traction, and performance of tires are related to the surface area of carbon blacks used in their production. Controlling the porosity of artificial bone allows it to imitate...

ENHANCED SOFTWARE CAPABILITIES, DATA REDUCTION, AND INSTRUMENT MONITORING MicroActive Software for TriStar II Plus The intuitive Micromeritics MicroActive control software for the TriStar II Plus enables the user to interactively evaluate isotherm data and reduce the time required to obtain surface area and porosity results. It is not necessary to generate reports to view results. Calculations, such as the BET surface area transform plot, can be easily generated, and adjusted. The selection bars allow for a range of data points to be quickly and easily selected. As a result, the summary of values...

EXTERNAL SAMPLE PREPARATION DEVICES Sample Preparation Devices Micromeritics offers numerous sample preparation devices for surface area and pore volume analysis. These devices combine flowing gas and/or vacuum with heat to remove atmospheric contaminants, such as water vapor and adsorbed gas, from the surface and pores of the sample. The quality of the data produced by surface area and pore volume analyses depends greatly on the cleanliness of the sample surface. All of Micromeritics sample preparation devices accept He, N2, Ar, and other non-corrosive gases. The Micromeritics Smart VacPrep™...

The Micromeritics FlowPrep 060 applies both heat and a stream of inert gas to the sample. The heat causes contaminants to desorb from the surface and the stream of inert gas sweeps them out of the sample tube. The unit lets you choose the temperature, gas, and flow rate best suited for your sample material and application. Needle valves allow you to introduce the flowing gas slowly to prevent fluidization of samples. Cryogen Transfer System The Micromeritics Cryogen Transfer System allows transferring liquid nitrogen or liquid argon from a nonpressurized storage dewar into smaller containers...
