Diffraction calibration standards showing (a) the concentration dependence of the 104 diffraction peak of calcite for slurry concentrations of 0.1–1.0 wt% under flow using the slurry cell shown in Fig. 2[link](c) with a 2 mm path length, (b) linear calibration curves of the integrated calcite 104 peak areas and heights as a function of concentration (intercepts were set to 0 and the calculated standard error of the slope is also provided), (c) the concentration dependence of the diffraction pattern of theophylline form II at slurry concentrations of 1.5–10.0 wt% in iso­propanol/water solutions, and (d) linear calibration curves of the integrated theophylline form II 310 diffraction peak areas and heights as a function of concentration, highlighting the fitted linear equation parameters.
