pressure vs composition diagram and the equipment to measure it

Gas sorption analysis is important in many fields of materials science and consumer product development. Some examples of current hot areas of technology involving gas-solid (or gas liquid) interactions include the development of energy storage materials, improved catalysts for petrochemical processing, advanced pharmaceuticals and food industries. At present, there is tremendous interest in the development of innovative materials for the transition to renewable energy. The science of gas sorption has become particularly critical in the advancement of materials for storing fuel gases such as hydrogen or natural gas, as well as for sequestration of greenhouse gases. Some exciting prospects for the chemical storage of gases include high-surface area and nanomaterials (graphitic carbons, CNT, zeolites, Metal-Organic-Framework MOFs). In the field of hydrogen-storage, a host of novel materials are being developed including high-pressure metalhydrides, light-weight complex hydrides, destabilized multicomponent chemical hydrides and amides, and other crossover materials such as ammonia borane encapsulated into mesoporous silica scaffolding.

Of prime interest in the discovery of these and many other new materials is the characterization of gas absorption, adsorption and desorption kinetics, capacity, thermodynamic properties, as well as cycling performance of reversible materials. Also important is the ability to measure the tolerance of catalyst, chemicals, and consumer products to air, moisture and low-level contaminants. These wide-ranging requirements and the need to perform analysis at both a research and a production level (milligrams to kilograms) have driven the development of the H-Sorb 2600, the ultimate tool for gas sorption analysis.

how to make a pressure composition diagram

Pressure-Composition Isotherms (PCT or PCI) is one of the most informative sorption measurements. The result is a plot of the equilibrium absorbed gas concentration in the material as a function of pressure and temperature.

The volumetric approach to PCI measurements consists of adding (or removing) gas to the sample volume in a small dose from one of the calibrated reservoirs and waiting for the resulting gas/solid equilibrium. The PCI curve is produced from the concentration of gas sorbed and the final pressure of each dose in a series of many doses that either increase (absorption) or decrease (desorption) in pressure. This is essentially a gas titration process.

The PCI plot will typically show an equilibrium plateau associated with the co-existence of the remaining unreacted material and the gas-reacted material, thus providing a complete phase diagram. For example, metal hydride materials that reversibly react with hydrogen show a well-defined plateau between the solid solution a-phase, where hydrogen is randomly dissolved within the solid matrix, and the b-phase, where hydrogen is in distinct structural sites and has bonded to the host solid material. In addition, precise dosing PCI measurements can provide detailed information on the presence of crystal structure changes, new phases and sorption kinetics as a function of gas concentration.
