US Patent:

20140004208, Jan 2, 2014

Filed:

Jun 29, 2012

Appl. No.:

13/537632

Inventors:

Jeffry Golden - Creve Coeur MO, US
Paul Brister - O'Fallon MO, US

Assignee:

BioMed Protect, LLC - S. Louis MO

International Classification:

A01N 59/00
A01P 1/00

US Classification:

424616

Abstract:

In one embodiment, a disinfectant composition includes a peroxide, a peracid, an anionic surfactant, a nonionic polymer, and one or both of a linear fatty alcohol and an alkyl pyrrolidone. The disinfectants provide greater killing rates for microbial populations in short periods of time, and therefore can be considered to be fast-acting disinfectants.

Charles Martin - Ellisville MO, US

Assignee:

BioMed Protect ,LLC - St., Louis

International Classification:

A01N 25/30

US Classification:

422 24, 424616, 422 28

Abstract:

A method is provided for the microbicidal treatment of a surface such as sanitization, disinfection, sterilization, and decontamination of a surface or object by use of an anti-microbial composition comprising an aqueous solution of peracetic acid and hydrogen peroxide with acetic acid, water soluble polymer containing lactam, and phosphate ester surfactant and little or no stabilizer, and according to the method enhanced microbicidal efficacy is obtained when the composition is applied onto a surface as a thin film wetting the surface so that a shorter contact time for a desired fractional reduction in microbial population is obtained Still further, the compositions comprise photosensitizer for light-activated anti-microbial efficacy.

International Classification:

G01N 21/76
G01N 21/75

US Classification:

436 94

Abstract:

An analytic method for the determination of the concentration of polysaccharide polymer in solution comprises the in-line derivatization of the polymer by reaction with sulfonate dye. The reaction results in an analyte-derivative, carried in a mobile phase, that can be detected and quantitatively determined by ultraviolet absorption or by fluorescence measurement. The method can provide sensitive and precise measurement in spite of limited solubility of the analyte.

US Classification:

Abstract:

A method is described to determine the remaining sorption capacity of activated-carbon-sorbent gas filters by measuring the breakthrough time for a test gas challenge to a test filter with known and controlled test conditions that include flow rate and temperature and the use of a calibration curve that has been established by prior testing of the test filter sorbent medium in calibration tests where the filter is exposed to a known quantity of gas surrogate for the challenge gases that the filter may sorb in service and then testing the test filter medium by challenge with a sparged gas that can be selectively detected to determine the breakthrough as a function of test gas. The apparatus using such a method comprises a portable system that includes a sparging test gas generator, a carrier gas system, a test filter canister holder, and a selective detector that can quantitatively monitor the test gas exiting the test filter canister. The method and apparatus can be used to determine the remaining sorption capacity of activated carbons filters, e.g., ASZM-TEDA carbon filters such as those used for building defense against chemical toxant attack, industrial accidents, and for tactical collective protection and for industrial ventilation and compliance with environmental regulations.
