<p num="1"><br/><br/><br/>A nebulant suitable for sterilization comprising finely divided liquid <br/>droplets suspended in a gas, said droplets including a solute, which is <br/>advantageously hydrogen peroxide and a solvent, for example water, wherein the <br/>droplets have a concentration of greater than 60 wt% of solute and an average <br/>diameter of less than 1.0 micron, preferably less than 0.8 microns. <br/>Sterilization using the nebulant may be carried out in suitably adapted <br/>apparatus by nebulising a solution comprising a sterilizing agent in a solvent <br/>to form a nebulant of finely divided particles of the solution in a gas <br/>stream, said solution including a solvent having a lower boiling point than <br/>the sterilizing agent; subjecting the nebulant to energy of a kind and for a <br/>duration sufficient to vaporize solvent in preference to sterilizing agent, <br/>whereby to increase the concentration of the agent in the nebulant particles; <br/>removing the solvent vaporized from the gas stream at or above atmospheric <br/>pressure and, if necessary, cooling the nebulant to below 70~ C; and exposing <br/>a surface to be sterilized to the nebulant of concentrated sterilizing agent <br/>for a time sufficient to sterilize the surface.<br/></p> |
