Abstract
Multiple early-load-release evaluations of sterilizing effectiveness for both “dry” and “wet” sterilizer loads, are made available by selective spectroscopic quantitative measurements of peak absorption of electromagnetic radiation, in selected UV and visible-light wavelength spectra developed for evaluating thermally-responsive change, in a fluid-state indicator material, which is correlated with the sterilizing effect of a selected cycle on bacterial spores of a sterilizer load. Biological evaluation of sterilizing effectiveness is made available with the same test devices, free of the risk of contamination, by measuring peak absorption of electromagentic radiation at developed wavelength spectra which evaluate pH change, if any, due to spore-growth, or the absence thereof, following a predetermined spore incubation period subsequent to completion of the thermal sterilizing cycle.
