WitrynaIdentification of potential impurities. Conduct QSAR analysis and expert review. Is the impurity likely to be genotoxic? Assessment of carryover. Does the impurity pose significant risk of carryover? Classify as non-genotoxic –treat as a general impurity. No further action. Quantification. Analyse level of impurity. Safety testing. WitrynaThe carryover of impurities (for example, sodium, chloride, copper, silica) with steam can be divided into two parts: mechanical carryover of the impurity with liquid water droplets entrained with the steam, and vaporous carryover of the impurity in steam. The total carryover is a sum of the mechanical and vaporous carryover. reading to luton train
