摘要： A pressurizable sample chamber of known volume holds a sample with unknown porosity characteristics. The sample chamber has a known pressure (or vacuum). A flow controller preferably controls the flow of the pure gas to be adsorbed by the sample in the sample chamber. A pressure monitor preferably monitors the pressure in the sample chamber. Once the pressure approaches a target pressure, the flow controller is closed. The pressure monitor continues to monitor the pressure until it stops changing when an equilibrium is attained. The amount of gas introduced into the system through the flow controller and the volume and final pressure of the sample chamber are used to calculate the amount of gas adsorbed. This calculation is subsequently used to determine the porosity characteristics of the sample. Some of these characteristics include, but are not limited to, pore distribution and surface area.

摘要： Methods, systems, and computer program products determine absorption, specific gravity, and/or porosity of construction materials undergoing analysis corresponding to different measurements of material samples divided from a “parent” construction material sample. Dry and wet weights of the samples are obtained under different conditions. In certain embodiments, the material sample is an aggregate that is held in liquid in a volumetric container and the container with the liquid and aggregate is weighed. Another weight of a second sample can be obtained. The second sample is encased in an evacuated vacuum-sealed bag that is opened while immersed in a liquid bath, at which time the weight can be obtained. The weight data can be used to calculate the parameter of interest. Other methods obtain one wet weight of the sample when it is positioned into the liquid bath at atmospheric pressure and the other weight is obtained when the sample is first held in an evacuated state in a sealed (compressible) bag is opened in the liquid bath. The weights can be used to determine the two densities. Other methods employ evacuating a chamber holding a quantity of material sample under water in the container or subcontainer and obtaining weights of the sample under several conditions. Another method increases the pressure in the chamber and obtains weights of the sample under various conditions. Each of the methods determine the material property based on the measured weights. Related devices are also described.

摘要： A method and apparatus for measuring the gas amounts adsorbed on a powder which directly measures pressure changes in a gas supply chamber with the use of differential pressure sensors between the gas supply chamber and a reference chamber which gas amount is maintained constant. Calculations of the gas amounts adsorbed are based on the pressure changes in a sample cell and the pressure changes in the gas supply chamber or a gas reference chamber. The method and apparatus of this invention measures the adsorption or desorption isotherm or gas uptake at constant pressure curve of a powder with, as compared with presently available measurement techniques, increased accuracy and resolution. The experimental data can be analyzed to obtain information on the surface area, pore size distribution, pore volume, pore structure and diffusion coefficient of the powder.

摘要： The invention concerns an apparatus for the titration and circulation of gases to determine metal hydride storing properties, with improved response time, greater dynamic range in terms of the usable amount of powder and the maximum pressure accessible and increased sensitivity. The invention also concerns a circulating apparatus considerably reducing the time for analysing and determining the properties of absorbent and adsorbent materials during a large number of adsorption-desorption cycles. Both sets of apparatus are provided with a reference tube inside their oven, near the sample-holder. Said sample-holder tube and reference tube are connected on either side of the differential pressure sensor, thereby considerably enhancing the overall performance of the titration system.

摘要： Testing process and apparatus for determining absorption properties of a porous specimen. The porous specimen is brought in a predetermined state of contact with the body of water held by a reservoir, for inducing water absorption in the porous specimen. A weight of the porous specimen is monitored for a predetermined time period once the contact is established to produce weight data over time. The predetermined state of contact is maintained substantially constant during the time period by permanent circulation of water in the reservoir. The absorption properties of the porous specimen are determined as a function of the weight data over time.

摘要： For use in a sorption analysis system, a method compensating for measuring error due to the time-dependent evaporation of liquid coolant and the resulting change in the level of the coolant and temperature increase around the stem of the sample cell, during a gas sorption analysis of a sample in the sample cell. This error compensation does not inhibit coolant evaporation and is without recourse to mechanical means or other physical contrivances for causing the system to act as if the coolant were not evaporating. This method employs fixed and time-dependent data, including: changing coolant level and sample cell stem temperature changes, both of which can be obtained off-line, cold zone volume changes, and volumes of adsorptive gas transferred into the sample cell, to generate progressive error correction; whereby, system output is being corrected throughout the duration of the sorption analysis.
