VHP Sterilization<br />
Process Parameters<br />
Temperature • Determination <strong>of</strong> temperature differences in the <strong>Isolator</strong><br />
• Reproducibility <strong>of</strong> temperature pr<strong>of</strong>iles<br />
Relative Humidity • Development <strong>of</strong> conditioning phase:<br />
Determination <strong>of</strong> time to reach max. relative humidity<br />
• Reproducibility <strong>of</strong> RH-pr<strong>of</strong>ile<br />
VHP-Concentration • Development <strong>of</strong> conditioning phase:<br />
Determination <strong>of</strong> time to reach max. VHP concentration<br />
• Reproducible run <strong>of</strong> concentration curve<br />
• Definition <strong>of</strong> “worst case” environmental conditions:<br />
low gas concentration at low temperatures in the isolator<br />
VHP-Distribution • Uniform distribution <strong>of</strong> VHP with chemical indicators<br />
