  • FROZEN FOOD THAWING
    Publication number: 20160286847
    Abstract: A method for thawing frozen food provided in a thawing appliance, the thawing appliance having a membrane forming a barrier between the frozen food and a fluid, the fluid at least partly surrounding the frozen food in use to transfer heat from the fluid to a corresponding surface area of the frozen food, the method including: controlling the fluid 5 at a thawing temperature; monitoring a state of the thawing of the frozen food and generating a state indicator; and controlling the fluid at a conservation temperature when the state indicator indicates a thawing completion state.

  • Sample support for desorption
    Patent number: 7582863
    Abstract: An apparatus and method for regenerating ion samples for a mass spectrometer are provided. Source samples are loaded on a support which is heated by a laser beam, desorbing the sample without ionization. The desorbed sample is carried by a carrier gas flow through a transfer tube, at the output of which it is ionized by corona discharge or photo-ionization. The obtained ionized sample may be analyzed in a mass spectrometer or used to serve any other appropriate purpose.
    Type: Grant
