In the OIP quality control environment, the risk of out-of-specification (OOS) measurements can be minimized by using the GCIP concept to identify and control errors.
In the OIP quality control environment, the complexity of the method can be a contributory cause of measurements that are deemed to be out-of-specification (OOS). The Good Cascade Impactor Practice (GCIP) concept is a means whereby the risk of such an occurrence can be minimized by following a logical process through which errors caused by the operator (MAN), the apparatus itself (MACHINE), the assay method (ANALYSIS or MEASUREMENT) and finally the formulation/delivery device (MATERIAL) are identified and controlled.
