Traditionally, the commonly used method for determining residue limits is predicated over the Fourman and Mullen approach, often called therapeutic dose–centered calculation.11 As well as a visually clear floor, this solution makes use of the greater stringent of the subsequent two criteria:

Appropriate use of air-locks and pressure cascade to confine possible airborne contaminant in just a specified location;
