Abstract

Deterioration of crystal surfaces during removal fromsolution prior to observation poses a problem for ex situ (atomicforce) microscopy studies. We use potash alum (KAl(SO4)2·12H2O) crystals as a model system and investigatethe variation of the following parameters: size, orientation, liftingrate, humidity, airflow, rinsing, and pollution. A model to describethe effects occurring during removal is developed and implicationsfor other systems are presented to minimize the discrepancy betweenin situ and ex situ surfaces. This discrepancy is minimized for potashalum when a crystal is lifted slowly from its solution in a verticalposition at a humidity below room humidity and in the absence of airflow.
