US Patent:

41070054, Aug 15, 1978

Filed:

Nov 11, 1976

Appl. No.:

5/741163

Inventors:

Vincent F. D'Agostino - Huntington Station NY
Joseph Y. Lee - Lake Grove NY
Edward H. Cook - Lewiston NY

Assignee:

Hooker Chemicals & Plastics Corporation - Niagara Falls NY
RAI Research Corporation - Hauppauge NY

International Classification:

C25B 116
C25B 124
C25B 1308

US Classification:

204 98

Abstract:

This disclosure is directed to fluorocarbon polymers, polymeric membranes, and electrochemical cells and processes. The polymers and membranes are produced by radiation techniques to provide improved products. For example,. alpha. ,. beta. ,. beta. -trifluorostyrene in an inert organic solvent is grafted onto an inert film, such as tetrafluoroethylene-hexafluoropropylene copolymer, by irradiation, i. e. with Co-60 gamma radiation at a dose of several Mrad. The grafted film is then sulfonated, preferably in a chlorosulfonic acid bath. The resulting film is useful as a membrane or diaphragm in various electrochemical cells such as chlor-alkali or fuel cells.

7/563648

Inventors:

International Classification:

G12B 1300
G01N 2159

US Classification:

356243

Abstract:

An apparatus for the calibration and quality assurance of a multichannel spectrophotometer, particularly an ELISA spectrophotometer, comprises film selectively exposed in the presence of a color to produce a series of filters having a known first color and linearly increasing optical density. The response of the spectrophotometer is measured against the known color and linearly increasing optical density. Additional filters of at least one additional color permit checking the color response of the spectrophotometer. An algorithm determines whether the response conforms to predetermined conditions. An output is produced to provide a record of the calibration and quality assurance of the spectrophotometer. The invention has particular utility for conducting calibration and quality assurance of ELISA spectrophotometers used in clinical laboratory screening for infectious diseases, such as Hepatitis B. and the AIDS viruses.
