Micromeritics introduced its latest material-characterisation instrumentation at Pittcon, which took place 9-12 March at McCormick Place in Chicago.
Included was the Gemini VII 2390 series surface area analysers, which produce accurate and repeatable surface area and porosity results.
The Gemini VII series permits low to high surface-area measurements without requiring exotic gases such as argon or krypton.
The Gemini VII 2390 is available in three model options.
The Gemini VII 2390a is ideal for rapid and accurate surface-area determinations.
It also provides standard methods for: single-point and multipoint BET and Langmuir surface areas, total pore volume, micropore analysis by the t-method and much more.
The Gemini VII 2390p provides additional precision with the addition of a saturation pressure tube, allowing the user to monitor the saturation pressure of the adsorptive on a continuous basis.
The instrument is designed to provide a rapid measurement of the adsorption isotherm.
The Gemini VII 2390t has all the capability of the 2390p, with the additional ability to perform a BJH or Dollimore-Heal pore-size distribution using adsorption and desorption isotherms of up to 1000 points.
This instrument also features a saturation pressure tube as well as a larger Dewar and longer sample tubes for extended analysis.
All models can be operated stand-alone or connected to a computer running Micromeritics's Gemini VII Windows software, greatly expanding data reduction and reporting capabilities.
The TriStar II 3020 Surface Area and Porosity Analyzer is an automated three-station analyser that can measure surface areas as low as 0.01M2/g using nitrogen.
It features a new krypton option that can measure surface areas down to 0.001M2/g.
A dedicated saturation pressure 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-litre 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 and the ability to read and compare historical TriStar and Gemini data to TriStar II data.
Micromeritics's first product addition under its Particulate Systems brand is the new Particle Insight dynamic image analyzer.
The Particle Insight is ideal for applications where the shape and diameter of raw materials is critical to the performance of the final product.
The Particle Insight offers up to 28 different shape parameters analysed in real-time in either aqueous or organic-solvent suspensions.
The system operates in a range suitable for a variety of industrial, biological and geological specimens from 3um up to 300um in its standard configuration.
Its recirculating sample module and precision optics acquire and report statistically valid measurements quickly, an essential quality control capability in many manufacturing processes.
Particle Insight features include the ability to track sample shape changes over time and the ability to store a collection of particle images.
The user also has the option of viewing only those particle images that meet any combination of the analyzer's 28-shape parameters.
Micromeritics's compact Mercury QuikVac can quickly clean-up mercury spills.
It can collect liquid mercury droplets and mercury-contaminated particulate matter.
Its compact size and light weight make it ideal for laboratory applications.
A replaceable 0.3-0.5 micron activated carbon filter traps mercury vapours and exhausts clean and safe air.
The instrument also includes a large-capacity 250ml recovery bottle.
