To illustrate the importance of a universal data format for adsorption data, we can compare data contained within an AIF to data digitized from a figure in a manuscript for the same experiment. The porous material DUT-6 (also referred to as MOF-205) is a metal-organic framework produced from zinc nitrate and two different different ligands; 2,6naphthalenedicarboxylate and benzene-1,3,5-tribenzoate. DUT-6 has mesopores of 2.4 nm, with dodecahedral geometry, and smaller cages of 0.9 nm that produce an extremely porous material with large adsorption capacities for n-butane (up to 1.1 g g -1 at 293 K), methane (230 mg g -1 at 100 bar and 298 K) and hydrogen (60 mg g -1 at 50 bar and 77 K). In the original manuscript, the nitrogen adsorption isotherm at 77 K was reported using relative pressure and a linear axis (Figure ). From this plot, the isotherm can be classified as type Ib, clearly exhibiting characteristics of a hierarchal pore system with micropores and mesopores. There is evidently a distinct step p/p 0 = 0.17, however, from this plot it is not possible to correctly identify low pressure features. The low pressure regions are important for understanding the process of sequential pore filling or for independent application of analysis methods, such as the Brunauer-Emmett-Teller (BET) method. The reported isotherm was digitized using WebPlotDigitizer, which uses a time-consuming but powerful point-picking methodology. In this methodology, each point in the graph is identified by clicking on the image area , and the location of the point in on-screen pixels is then converted to data values based on an axes calibration. The digitized isotherm and the data from the experiment, when plotted on semi-log axes, clearly shows that important low pressure information, such as the point of initial pore-filling, is lost when this information is simply included as a figure in a manuscript (Figure ).
