Patents by Inventor Thomas Summers West

Thomas Summers West has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Atomic absorption and fluorescence spectroscopy
    Patent number: 3947125
    Abstract: In analysing a sample by atomic absorption or atomic fluorescence spectroscopy, the cloud of free atoms which interact with incident radiation is produced by heating a graphite body, disposed below the interaction region, on which the sample has been deposited. The body is heated in an inert atmosphere by passing electric current through it. Compact forms of apparatus which may replace the burner system of a conventional spectrometer utilise a horizontally disposed graphite rod around which flows a stream of inert gas.

  • Analytical spectroelectrochemistry
    Patent number: 3947124
    Abstract: In a method of analytical spectrometry, material to be analysed is introduced in solution between a pair of charged electrodes so as to produce a light-absorbing atomic or molecular species by electrolysis at an electrode surface. A beam of light of an appropriate wavelength is directed through the solution into the vicinity of the relevant surface and light emerging from this vicinity is detected. Specific forms of apparatus are described for practising the method, using either absorption or fluorescence techniques.
