Spectroscopic analysis of chemical substances
An intense electric field is employed as the external source of energy in carrying to a spectroscopic
analysis of a chemical composition. The substance to be analyzed is placed between an insulated
conductive electrode and a ground reference. A high voltage is then applied to the electrode to
generate an electric field of a predetermined intensity within the test sample. As a result of the
energy absorbed, the constituents of the sample are caused to release their characteristic spectral
emissions. These emissions are optically filtered to isolate the wavelength of interest which is
passed to a light detector and registered on a photon counting system. The procedure is especially
and uniquely applicable for conducting an in situ chemical analysis of human sweat, thus offering a
valuable aid in the diagnosis of various medical abnormalities.
US Patent No: 4203848
Processes of making a porous membrane material from polyvinylidene fluoride, and products
Covers processes for making microporous membranes and molecular filtration membranes from
vinylidene fluoride polymers, and the products so produced. A continuous version of the process
consists of applying a layer of a solution of a polyvinylidene fluoride polymer to a rigidly
supported surface of a backing belt to form a film, then passing the belt through a formation bath,
in which the membrane is formed. To form the polymer solution, the polymer is dissolved in a
liquid vehicle that will dissolve up to about 25% by weight of the polymer at a temperature of at
least 50.degree. C. but that dissolves substantially less of the polymer at about 20.degree. C. (room
temperature). The polymer solution is formed at 50.degree. C. or higher, and the formation bath is
maintained at about room temperature. The formation bath is a mixture of the liquid vehicle solvent
with a second liquid that is miscible with the solvent but that is not itself a solvent for the polymer.
The film is maintained immersed in the formation bath until it has been converted to a porous
membrane whose pore structure is essentially fully formed, by leaching of the solvent from the film
