TriStar II Series Surface Area and Porosity Analyzers

Information on the surface area and porosity of materials can be vital in understanding their nature, predicting their behaviour in use and assessing their quality. In choosing an analytical instrument to investigate these factors, key considerations include accuracy, speed and affordability. On all three counts, analysts will find that the TriStar II series from Micromeritics scores highly.

Comprising two models, the TriStar II and the TriStar II PLUS, it is a three-station surface area and porosity analyzer with full automation. It not only makes routine quality control analysis quicker and more efficient but satisfies the requirements of most researchers. In terms of delivering accuracy, resolution and data reduction, its capabilities are impressive – and yet it comes at a very attractive price.

This versatile instrument includes a Krypton Option which allows measurement of very small surface areas. Its combination of analysis methods and data reduction can be adapted to each specific application to optimise analysis. For laboratories with particularly high demands in relation to throughput and data quality, the TriStar II PLUS adds a number of extra hardware and software features to the TriStar II package.

In view of its small footprint, the number of features packed into the TriStar II is quite exceptional. A few examples will be given here, but a visit to www.micromeritics.com will reveal many more.

Simultaneous, independent use of its three analysis ports allows three BET surface area measurements to be completed within just 20 minutes. Throughput can be increased further by using one computer to operate up to four TriStar analyzers.

The standard nitrogen system will deal with surface area measurements down to 0.01 m2/g, but argon and carbon dioxide, as well as other non-corrosive gases including butane, methane and similar light hydrocarbons, can also be accommodated. Measurements as small as 0.001 m2/g are possible using the Krypton Option.

Other capabilities include: continuous measurement of saturation pressure; incremental or fixed dosing; measurement, calculation or manual entering of free space; operator-free collection of complete adsorption and desorption isotherms; collection of up to 1,000 data points; versatile data archiving and networking. The full list of functions, support features and options is much longer.
