Title: Testing for bacterial sterilizing effectiveness, and test indicator manufacture and use
Inventor: GILLIS JOHN R
IPC: A61L2/28
Filed: 2002-09-23
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.

Abstract: A complexing ligand for forming a complex with a cation, the ligand comprising an aromatic component including two or more attachment sites for the cation, an optionally substituted amine, such as an aminoalkylene group, and a hydrocarbon chain of from 1 to 12 carbon atoms in length. The amine component of the ligand is capable of taking on an internal counterion (H+) so that the complex of the target cation and ligand has an overall neutral charge. Such ligands can be used to extract a target cation or cations from an aqueous solution. This has particular application for the separation of aluminium and silicon in aqueous liqors in a Bayer process. The ligand can be a simple compound formed by the Mannich condensation of catechol with formaldehyde and an amine. The ligand may alternatively be a bis-ligand, a polymer or an ion exchange resin. A range of new compounds and intermediates are also described.
