ASAP 2020 Applications

A World of Applications

The fully automated ASAP 2020 is an essential tool for providing surface area and porosity measurements on a wide variety of materials. Here are just a few of the most commonly used applications:

Pharmaceuticals – Surface area and porosity play major roles in the ability to purify, process, blend, tablet, and package a drug substance. The useful shelf life and the dissolution rate (governing how rapidly the medicine becomes available to the body) depend upon the surface area and porosity of the material.

Ceramics – Surface area and porosity information helps to determine curing and bonding procedures, ensure adequate green strength, and produce a final product of desired strength, texture, appearance, and density.

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

Carbon Black – Tire manufacturers have discovered that the surface area of carbons affects the wear lifetime, traction, and performance of tires. The intended use of the tire, or the type of vehicle on which it will be placed, determines whether low or high surface area carbons will be required.

Paints and Coatings – The surface area of the pigment or filler influences the gloss, texture, color, color saturation, brightness, solids content, and film adhesion properties. Porosity can control application properties such as fluidity, drying or setting time, and film thickness.

Catalysts – The active surface area and the porous structure of catalysts have a great influence on production rates. Limiting the pore size allows only molecules of desired sizes to enter and leave, creating a selective catalyst that will produce primarily the desired product. Chemisorption experiments are valuable for the selection of catalysts for a particular purpose, qualification of catalyst vendors, and the testing of a catalyst’s performance over time to establish when the catalyst should be reactivated or replaced.

Projectile Propellant – The surface area of propellants used in the manufacture of munitions directly affects the burn rate. Too high a rate can be dangerous; too low a rate can cause malfunctions and inaccuracy.

Medical Implants – The surface area and porosity of the materials used in medical implants influence the adhesion of the material to bone or natural tissue.

Cosmetics – Surface area is often used by cosmetic manufacturers as a predictor of particle size when agglomeration tendencies of the fine powders make analysis with a particle-sizing instrument difficult.

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

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

Fuel Cells – Fuel cell electrodes require high surface area with controlled porosity to produce optimum power density

Electronics - The manufacture of compact, miniature capacitors using a minimum of costly raw material requires the development of controlled, high surface area material with a carefully designed pore network,
