Micromeritics ASAP 2000, ASAP 2010, and ASAP 2400 analyzers perform surface area measurements by the static volumetric method. When analyzing samples on these instruments, the samples are first out-gassed using heat and/or vacuum. Typically, nitrogen is the analysis gas for the surface area measurements; however, krypton is available for very low surface areas.

Micromeritics FlowSorb II 2300 performs single point surface area measurements by the flowing gas method producing quick and accurate results.

Micromeritics TriStar 3000 gas adsorption analyzer provides surface area measurements in a fast and efficient manner using a three sample station set up.

IMPORTANCE:

The surface area of materials is important to the formulator of compounds ranging from aluminas to pharmaceuticals to catalytic supports and ceramics. For example, the dissolution time of drugs may be determined by surface area.

RESULTS:

Reports vary from approximately 5 pages for a 5 point surface area (B.E.T or LANGMUIR) to one page for a single point surface area report.
