  • Patent number: 7741102
    Abstract: The present invention relates to sensitive SE(R)RS based methods for detecting analytes such as explosives and drugs, which may be present in a sample at extremely low levels. The methods may be generally carried out in situ employing novel chemistry which is compatible with flow-cell technology and with time-scales and concentrations required for rapid and informative screening of large numbers of samples. The present invention also relates to novel compounds e.g. synthons and apparatus for use with the methods disclosed.
    Type: Grant

  • Patent number: 6750187
    Abstract: A method of removing cooked-, baked-, or burnt-on food soil from cookware and tableware comprising delivering a plurality of compositions including at least one organic solvent composition into the same or different cycles of an automatic dishwashing machine and washing the soiled cookware/tableware in the resulting solvent-containing wash liquor. The method includes the storage and delivery of organic solvent compositions and dishwashing detergent composition from multi-compartment containers. The method provides excellent removal of stubborn soils which are very difficult to remove in a conventional automatic dishwashing process.

  • Patent number: 6740628
    Abstract: A method of removing cooked-, baked-, or burnt-on food soil from cookware and tableware comprising washing the cookware/tableware in an automatic dishwashing machine in the presence of an organic solvent system having a volatile organic content of less than about 50% by weight and a wash liquor concentration of from about 100 ppm to about 10000 ppm. The method includes the storage and delivery of organic solvent compositions and dishwashing detergent composition from multi-compartment containers. The method provides excellent removal of stubborn soils which are very difficult to remove in a conventional automatic dishwashing process.
