A system according to claim 1 wherein the container is impermeable to microorganisms. 3. A system according to claim 1 wherein the second space is detachable from the first space. 4. A system according to claim 1 wherein the container comprises a pouch. 5. A system according to claim 1 wherein the indicator comprises a biological indicator. 6. A system according to claim 1 wherein the indicator comprises a chemical indicator. 7. A system according to claim 6 wherein the container comprises a pouch and wherein the chemical indicator is printed on the pouch inside the second space. 8. A system according to claim 1 and further comprising a flow restriction between the first space and the second space. 9. A system according to claim 1 wherein the first space is divided into two or more subspaces connected in series between the source of antimicrobial fluid and the second space. 10. A system according to claim 1 wherein the antimicrobial fluid comprises hydrogen peroxide. 11. A system according to claim 1 and further comprising a fan adapted to assist flow through the container from the source of antimicrobial fluid to the second space. 12. A system for monitoring a sterilization or disinfection process comprising:a container defining a first space and a second space, the first space and second space being in fluid communication with each other;the first space being adapted to contain one or more articles to be sterilized or disinfected;the second space having therein at least one indicator for indicating at least one parameter relevant to the sterilization or disinfection process;a flow restriction between the first space and the second space;an antimicrobial source for providing an antimicrobial agent to the first space; andwherein the second space is in fluid communication with the antimicrobial source only through the first space. 13. A system for monitoring a sterilization or disinfection process comprising:a container defining a first space and a second space, the first space and second space being in fluid communication with each other;the first space being adapted to contain one or more articles to be sterilized or disinfected;the second space having therein at least one indicator for indicating at least one parameter relevant to the sterilization or disinfection process;the first space being divided into two or more subspaces connected in series between the source of antimicrobial fluid and the second space;an antimicrobial source for providing an antimicrobial agent to the first space; andwherein the second space is in fluid communication with the antimicrobial source only through the first space. 14. A system according to claim 13 wherein at least a portion of the subspaces are detachable from the container. 15. A system for monitoring a sterilization or disinfection process comprising:a container defining a first space and a second space, the first space and second space being in fluid communication with each other;the first space being adapted to contain one or more articles to be sterilized or disinfec ted;the second space having therein at least one indicator for indicating at least one parameter relevant to the sterilization or disinfection process;an antimicrobial source for providing an antimicrobial agent to the first space wherein the antimicrobial fluid comprises hydrogen peroxide; andwherein the second space is in fluid communication with the antimicrobial source only through the first space. 16. A system for monitoring a sterilization or disinfection process comprising:a container defining a first space and a second space, the first space and second space being in fluid communication with each other;the first space being adapted to contain one or more articles to be sterilized or disinfected;the second space having therein at least one indicator for indicating at least one parameter relevant to the sterilization or disinfection process;an antimicrobial source for providing an antimicrobial agent to the first space;wherein the second space is in fluid communication with the antimicrobial source only through the first space; andfurther comprising a fan adapted to assist flow through the container from the source of antimicrobial fluid to the second space. 17. A method for monitoring a disinfection or sterilization procedure comprising the steps of:providing a container having a first space and a second space in fluid communication with each other;placing an article to be disinfected or sterilized into the first space;placing at least one indicator into the second space;providing an antimicrobial agent to the first space;flowing said antimicrobial agent to the second space only from the first space and reading a relevant function of the disinfection or sterilization procedure with the indicator; andwherein the antimicrobial agent comprises hydrogen peroxide. 18. A method according to claim 19 wherein the antimicrobial agent comprises hydrogen peroxide vapor. 19.
