摘要： A high pressure mercury porosimeter for continuous pore volume distribution measurements that simultaneously receives two or more test sample penetrometers, each containing a powder or porous solid sample to be tested. Two or more individual tests can be simultaneously performed per high pressure cycle in a single porosimeter. Only one access port is required to access 2 or more penetrometers greatly increasing sampling throughput, reducing multiple test time requirements without significant equipment cost increase.

摘要： As understood, the effectiveness of using mercury penetration or intrusion into a powder sample to measure the pore volume distribution thereof is based on negative capillarity, i.e. that a porous solid will repulse a non-wetting liquid, such as mercury, except as the mercury is forced into the pores thereof by pressure. Whereas in the prior art the mercury is intruded into the powder sample at pressures in an ascending order, but with gaps therebetween and thus according to a "discontinuous" pressure pattern, the within inventive method practices the mercury intrusion technique according to an ascending pressure pattern that is "continuous". The pore volume distribution curve produced by the within inventive method is thus more accurate than that of prior art data-gathering methods, since it is produced without interpolation between curve-plotting data points.
摘要翻译：如所理解的，使用汞渗透或侵入粉末样品以测量其孔体积分布的有效性基于负的毛细作用，即，多孔固体将会使非润湿液体（例如汞）反冲洗，除非汞是通过压力迫使其进入其孔。而在现有技术中，汞以升序的压力侵入到粉末样品中，但是在其间具有间隙，因此根据“不连续的”压力图案，本发明的方法根据上升压力图来实施汞侵入技术那就是“连续”。因此，本发明方法产生的孔体积分布曲线比现有技术的数据收集方法更精确，因为它在曲线绘制数据点之间没有内插的情况下产生。

A plurality of isolation valves are connected within the plurality of supply lines. At least one isolation valve is connected between the at least one pressure measurement device and the manifold, and between the at least one pressure measurement device and the at least one sample cell. At least one vacuum supply evacuates the manifold, the at least one sample cell, the plurality of supply lines, the plurality of isolation valves, and the at least one pressure measurement device. The apparatus minimizes errors associated with sorption measurements on sample material at temperatures below the critical temperature of the sorbable gas supply.

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.

摘要： An adsorption and desorption analyzer for performing analyses on samples comprises a manifold for selectively storing one or two gases or vapors having different critical temperatures, at least two cells constructed and arranged to store a sample for analysis, a supply line having an isolation valve connecting each cell to the manifold, an absolute pressure transducer for monitoring the pressure in the manifold, vacuum means, a microprocessor for controlling the operation of the isolation valves and the application of gas or vapor or vacuum to the manifold and a coupling line having a differential pressure transducer having a smaller range than the range of the absolute pressure transducer, enables an operator to determine data points for characteristics of the samples under study more precisely and more rapidly than is possible using an analyzer having an identical absolute pressure transducer for each cell to determine the characteristics of the samples stored in the cells. The analyzer is also constructed and arranged to determine the characteristics of additional samples in addition to the first pair of samples compared.

摘要： 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.
