Table summarizes the diffusion rates obtained by FT-CSFR and sine wave CSFR to show how the FT technique compares to traditional CSFR. Additionally, Figure shows a parity plot between FT-CSFR and CSFR measured rates to visually compare the data. In general, FT-CSFR agrees with CSFR within about a factor of 3, which is excellent agreement considering the significantly shortened acquisition time of this technique. Also, the agreement between FT-CSFR and CSFR is consistent across several orders of magnitude of the measured rate, with the greatest error associated with the measurement of MOF-303 at 10% RH, which is near the steep portion of the isotherm. Diffusion rate measurements at or near the isotherm step are typically the most difficult to measure via CSFR, as shown in previous work, and this is also the case for FT-CSFR. Additionally, it is worth noting that FT-CSFR neither consistently over-or underestimates the diffusion rates, as seen in Figure .
