Title:
METHOD AND DEVICE FOR ANALYZING SAMPLE
Document Type and Number:
Japanese Patent JPS6126841
Kind Code:
A
Abstract:
An automatic adsorption and desorption analyzer for independently performing analyses on a plurality of powder samples includes a manifold connected through a plurality of independently operated valves to a corresponding plurality of sample cells. A pressure transducer measures the manifold pressure and a plurality of pressure transducers are respectively coupled to the sample cells to independently measure the pressure at each of the sample cells. The system measures the volume of gas adsorbed (desorbed) by each of the samples that is required to establish specified equilibrium pressures at the sample cells, thereby to provide pressure-volume points which can be used to prepare adsorption (or desorption) isotherms, BET curves, and other information concerning the properties of the samples.
