Decontamination vs disinfection
Decontamination – a process that eliminates viable bioburden via use of chemical agents.
Disinfection – The process by which surface bioburden is reduced to a safe level or eliminated. Some disinfection agents are effective only against vegetative microbes, while others possess additional capability to effectively kill bacterial and fungal spores.
Depyrogenation – A process used to destroy or remove pyrogens (e.g. endotoxin).
