ABSTRACT:
The surface area of a plurality of samples is measured in an apparatus in which these samples are all included in a housing, subjected to adsorption of the adsorbing fluid and seriatim moved into a desorption zone in which one sample at a time is subjected to a desorption step. In another embodiment, a plurality of individual sample holders are each provided with an individual heating element to allow seriatim desorption by switching the heating of the samples from one heating element to the next. No movement of the sample holders is required in this embodiment. The apparatus and operation lends itself to automation.
