TriStar II Plus 3030

The Micromeritics TriStar II Plus is a fully automated surface area and porosity analyzer that delivers a rapid high throughput analysis with high accuracy. The three-station unit increases the speed and efficiency of routine quality control analyses, yet has the accuracy, resolution, and data reduction capability to serve research requirements. The instrument combines versatility in analysis methods and data reduction to allow analyses that are customized to application needs.

• The TriStar II Plus provides an efficient high throughput system with three sample ports operating simultaneously and independently. For additional throughput, up to four units can be operated with one computer.

• Surface areas as low as 0.01 m²/g can be measured with the standard nitrogen system. A Krypton Option can extend surface area measurements to as low as 0.001 m₂/g.

• The TriStar II Plus accommodates analysis with a variety of adsorbates including argon, carbon dioxide, and other noncorrosive gases such as butane, methane, and other light hydrocarbons.

• Free space can be measured, calculated, or manually entered providing maximum flexibility in accommodating special sample types and emphasizing speed when needed.

• Isothermal Jackets ensure a constant thermal profile along with the full length of both sample and saturation pressure (P₀) tubes.

• Micromeritics MicroActive data reduction and control software enables the user to interactively calculate surface area and porosity. User-selectable data ranges through the graphic interface allow direct modeling for BET, t-Plot, Langmuir, and DFT interpretation.

• The enhanced software capabilities allow comprehensive pore size distribution data by gas adsorption & mercury intrusion overlay and advanced NLDFT.

• MicroActive software for the TriStar II Plus also includes a powerful utility that allows the user to overlay a mercury porosimetry pore size distribution with a pore size distribution calculated from gas adsorption isotherms. This import function allows users to rapidly view micropore, mesopore, and macropore distributions in one easy-to-use application₂ / g fajlagos felület is mérhető.
• The Advanced NLDFT model allows the user to combine the information gathered from nitrogen and carbon dioxide isotherms to deliver a full pore size distribution on materials (such as carbon slit pores) where pores of molecular sizes are present. The range of pore size analysis in this method is extended to smaller pore sizes compared to the standard nitrogen analysis. This is since CO2 can access some very small micropores that are not accessible to N2 at cryogenic temperatures due to size restrictions, connectivity problems, or extremely slow diffusion

 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.

 Adsorbents

Knowledge of surface area, total pore volume, and pore size distribution is important for quality control of industrial adsorbents and in the development of separation processes. Surface area and porosity characteristics affect the selectivity of an adsorbent.

 Batteries and Fuel Cells

Optimizing the surface area and porosity of the components improves storage capacity and energy generation.

 Activated Carbons

Surface area and porosity must be optimized within narrow ranges to accomplish gasoline vapor recovery in automobiles, solvent recovery in painting operations, or pollution controls in wastewater management.

 Paints and Coatings

The surface area of a pigment or filler influences the gloss, texture, color, color saturation, brightness, solids content, and film adhesion properties. The porosity of a print media coating is important in offset printing where it affects blistering, ink receptivity, and ink holdout.

 Pharmaceuticals

Surface area and porosity play major roles in the purification, processing, blending, tableting, and packaging of pharmaceutical products as well as their useful shelf life, dissolution rate, and bioavailability.

 Catalysts

The active surface area and pore structure of catalysts influence production rates. Limiting the pore size allows only molecules of desired sizes to enter and exit, creating a selective catalyst that will produce primarily the desired product.

 Ceramics

Surface area and porosity affect the curing and bonding of greenware and influence strength, texture, appearance, and density of finished goods. The surface area of glazes and glass frits affects shrinkage, crazing, and crawling. Nanotubes

 Carbon Black

The wear lifetime, traction, and performance of tires are related to the surface area of carbon blacks used in their production. Medical Implants Controlling the porosity of artificial bone allows it to imitate real bone that the body will accept and allow tissue to be grown around it.

 Nanotubes

Nanotube surface area and micro porosity are used to predict the capacity of a material to store hydrogen.
