  • the present invention relates to apparatus for use in the detection of the aicoho! content of a iiquid such as a beverage, in addition the present invention relates to a method for detecting the alcohol content of a liquid such as a beverage.
  • An alcoholic beverage is a drink which contains typically about 3% to about 40% alcohol.
  • Such beverages can generally be divided into four main classes. These are beers which are fermented from grain mash, ciders which are fermented from fruit juice, wine which is fermented from grape juice, and distilled beverages. Distilled beverages are those where the alcohol is concentrated by distillation. These distilled beverages, which have an alcohol content of at least 20% by volume, are generally referred to as spirits. However, most distilled beverages have an alcohol content around 40%.
  • This counterfeit product may simply be over-diluted such that it does not have the alcohol content which the purchaser is expected.
  • the counterfeit beverage may be made from cheap materials and not have the taste of the genuine beverage.
  • testing the alcohol content requires samples to be sent to a laboratory for analysis.
  • test would be useful to other users such as bar, nightclub, venue or restaurant operators and staff.
  • medica! staff in an emergency situation to check the a!coho! content in a beverage bottle found with a patient.
  • a suitable test may even be useful in offices and education establishments.
  • Apparatus for detecting alcohol in the blood which comprises a chamber associated with a delivery path for a sample volume; conditioning means for the chamber to temperature condition the sample volume in a vapour equilization with air in a head space for the chamber; and a fuel ceil associated with the head space to sample the vapour equilizatson to determine the present electrical voltage in the fuei cell indicative of alcohol level in the vapour equilizatson relative to a temperature condition.
  • This arrangement enables the blood alcohol content to be calculated by reference to a calibration curve. This arrangement enables the rapid detection of blood alcohol to be detected.
  • apparatus for detecting alcohol in a liquid comprising:
  • a fuel cell associated with the cover such that in use the fuel cell is in contact with the interior of the liquid container, said fuel cell being configured to determine the electrical voltage in the fuel cell, said fuel cell being indicative of the type and/or amount of alcohol present.
  • the cover may simply be a plate which can be placed over a container such as a glass or bottle containing the liquid. When the cover is in position, the fuel cell will be in contact with the head space between the top of the liquid and the underside of the cover.
