what does surface area measure
There are different methods used to measure surface area and each method can yield different results. Most methods are based on the isothermal adsorption of nitrogen. Either a single point or multipoint method is used to calculate the surface area.he total to determine the method used to determine surface area, Table 1, showed that six of the respondents used a single point surface area of a catalyst can be measured by either a multipoint or single point technique.
