Powder XRD profiles of a diastereomeric salt sample, showing the open air drying process starting from its wet state during repeated diffraction measurement series with prolonged measurement time in open air. (: first run, as short as 3 min; : immediately repeated run with a longer measurement time of 15 min; : third run consecutively and taking as long as 40 min.
