Abstract
A system for abatement of sterilizing gas may include a device package having a device disposed therein and a sterilizing gas abatement member disposed adjacent to the device package. The sterilizing gas abatement member may comprise a base material and a catalyst comprising sulfonic acid functional groups. The catalyst is configured to abate a sterilizing gas.
Claims20
A system for abatement of sterilizing gas, the system comprising:
- a device package having a device disposed therein;
- and
- a sterilizing gas abatement member disposed adjacent to the device package, the sterilizing gas abatement member comprising:
- a base material;
- and
- a catalyst comprising dye molecules having sulfonic acid functional groups;
- wherein the catalyst is configured to abate a sterilizing gas present adjacent to the device package.
A sterilizing gas abatement system comprising:
- a container configured to hold one or more sterilized devices;
- a sterilizing gas abatement member positioned within or surrounding the container, the sterilizing gas abatement member comprising:
- a porous matrix formed from a base material and a catalyst;
- wherein the base material provides structural integrity to the porous matrix;
- wherein the catalyst comprises dye molecules having sulfonic acid functional groups;
- and
- wherein the catalyst is configured to convert ethylene oxide gas to ethylene glycol.
A method of manufacturing a sterilizing gas abatement member, the method comprising:
- mixing a base material with an acid and water solution to form a first mixture;
- acidifying dye molecules having sulfonate functional groups;
- adding the acidified dye molecules to the first mixture to form a second mixture;
- pouring the second mixture into a mold;
- and
- removing water from the second mixture to form a porous matrix.
