Benefits

• Ultra-stable detector eliminates drift and need for constant readjustment.
• Cold trap conveniently located in front vs. side placement, as in other instruments. This placement reduces the chance of breakage as compared to side placement.
• Single-injection calibration requires only one control setting. Adaptable to any non corrosive adsorbate mix.
• All controls and displays are at eye/arm level, out of spill zone.
• Built-in sample preparation.
• The FlowSorb III 2310 features a built-in dewar elevator for completely automated analysis and rewarming fan for rapidly warming the sample tube to increase the speed of sample analysis
• The thermal conductivity detector eliminates temperature-induced drift resulting in highly repeatable results.
• Single-injection calibration provides fast start-up and high sample throughput.
• The FlowSorb III 2305 features a dewar support latch system that provides one-hand convenience and safeguards against liquid nitrogen spills.
• Five different types of sample tubes are available including a monolith-type tube for large samples.

 

Applications

Pharmaceuticals

Porosity and surface area play major roles in the purification, processing, blending, tableting, and packaging of pharmaceutical products as well as a drug’s useful shelf life, its dissolution rate, and bio-availability.

Ceramics

Pore area and porosity affect the curing and bonding of greenware and influence strength, texture, appearance, and density of finished goods.

Adsorbents

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

Catalyst

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.

Aerospace

Surface area and porosity of heat shields and insulating materials affect weight and function.

Fuel Cells

Fuel cell electrodes require controlled porosity with high surface area to produce adequate power density.

Geoscience

Porosity is important in groundwater hydrology and petroleum exploration because it relates to the quantity of fluid that a structure can contain as well as how much effort will be required to extract it.

Filtration

Pore size, pore volume, pore shape, and pore tortuosity are of interest to filter manufacturers. Often, pore shape has a more direct effect upon filtration than pore size because it strongly correlates with filtration performance and fouling.

Construction Materials

Diffusion, permeability, and capillary flow play important roles in the degradation processes in concrete, cement, and other construction materials.

Paper

The porosity of print media coating is important in offset printing where it affects blistering, ink receptivity, and ink holdout.

Medical Implants

Surface area and porosity of heat shields and insulating materials affect weight and function.
