NOVA touch ® Software ? surface area & pore size analyzer 10 Before performing gas sorption exper- iments, solid surfaces must be freed from contaminants such as water and oils. Surface cleaning (degassing) is most often carried out by placing a sample of the solid in a glass cell and heating it under vacuum or flowing gas. Figure 1 Illustrates how a solid particle containing cracks and orifices (pores) of different sizes and shapes may look after its pre - treatment. Once clean, the sample is brought to a constant temperature by means of an external bath. Then, small amounts of a gas (the adsorbate) are admitted in steps into the evacuated sample chamber. Gas molecules that stick to the surface of the solid (adsorbent) are said to be adsorbed and tend to form a thin layer that covers the entire adsorbent surface. Based on the well-known Brunauer, Emmett and Teller (B.E.T.) theory, one can estimate the number of molecules required to cover the adsorbent surface with a monolayer of adsorbed molecules, N m (see Figure 2 ). Multiplying N m by the cross-sectional area of an adsorbate molecule yields the sample’s surface area. Continued addition of gas molecules beyond monolayer formation leads to the gradual stacking of multiple layers (or multilayers). Their formation occurs in parallel to capillary condensation (see Figure 3 ). The latter process is approximated by the Kelvin equation, which quantifies the proportionality between residual (or equilibrium) gas pressure and the size of capillaries capable of condensing gas within them. Methods such as the classical one by Barrett, Joyner and Halenda (B.J.H.), or the more accurate Density Functional Theory (DFT) models, allow the com- putation of pore sizes from equilibrium gas pressures. Experimental isotherms of adsorbed gas volumes versus relative pressures (at equilibrium) are converted to cumulative or differential pore size distributions. As the equilibrium adsorbate pressures approach saturation, the pores become completely filled with adsorbate (see Figure 4 ). Knowing the density of the adsorbate, one can calculate the volume it occupies and, consequently, the total pore volume of the sample. If at this stage the adsorp - tion process is reversed by withdrawing known amounts of gas from the system in steps, one generates desorption isotherms. The resulting hysteresis leads to isotherm shapes that can be related to those expected from particular pore shapes.

Quantachrome supplies complete assemblies which include two-stage regulators with dual gauges, cylinder connector, isolation valve and 1/8" gas line connector. The regulators feature stainless steel, non-venting diaphragms and the appropriate CGA fitting for specific gases. Different assemblies are available for nitrogen (and other inert gases including helium), hydrogen, carbon monoxide, oxidizing gases, etc. Rotary Micro Riffler As in most powder and porous materials characteriza - tion studies, surface area and pore size determinations generally require sub-samples much smaller than the original samples. The Rotary Micro Riffler uses the most accurate way of splitting a powder sample into smaller fractions - spin riffling. Its vibrating hopper features adjustable feed rates and its variable-speed collector uses standard or micro test tubes for representative sub-sample collection. Small Cold Zone For Increased Sensitivity Coolant level controlled here creates a small cold zone. Coolant level controlled here creates a large cold zone. Some Instruments N OVAtouch Measurements at lower absolute pressures can also be very effective in this regard, and this is why krypton (whose saturation pressure at liquid nitrogen tempera - ture is approximately 1/300 th that of nitrogen at the same temperature) is often employed when measuring extremely low surface areas (less than one square meter total for example). The amount of unadsorbed gas is also a function of the temperature of the free space: the higher it is the fewer molecules it contains for a given pressure, and the lower it is the more molecules are present at the same pressure. In any manometric instrument part of the free space is “warm” (not in coolant), and part is “cold” (submerged in coolant). Therefore it is advantageous to minimize the volume of free space that is cold, since every cm 3 at liquid nitrogen temperature (77.4K) contains almost four times as many unadsorbed molecules as every cm 3 does around room temperature (e.g., 298K). It is true that for any cell geometry more of it should be warm and less should be cold for maximum sensitivity. The sensitivity of a manometric sorption analyzer depends on the internal volume of the measurement zone (free space) and how many adsorbate molecules remain unadsorbed. The goal always therefore is to minimize the amount of unadsorbed gas occupying the free space. For that purpose, filler rods that occupy the stem portion of the sample cell are commonly employed. Additionally the bulbous portion of the sample cell can be selected to minimize the free space that is consistent with the bulk volume of the sample and its adsorption capacity.
