摘要:
A method is provided for separating superalloy metal powder from contaminants, such as process-produced contaminants, by enhancing the magnetic properties thereof in a carburizing atmosphere followed by magnetic separation of the contaminants from the superalloy metal powder to thereby enhance the concentration of the contaminants. Heating or mechanical agitation or both are employed to resist agglomeration of the metal powder before magnetic separation thereof from the contaminants. Certain preferred times and temperatures are disclosed.

The present invention provides a method and apparatus for processing to improve the properties of pyrolysis oil and, as a result, the commercial value of the same. The net result is creation of an oil with a much lighter color in lieu of the black color, reducing or elimination the undesired sulfury/amine aroma and reducing the amount of PAH which is believed to be a carcinogen.

Methods and apparatus for monitoring air samples for the presence of the explosive TATP are disclosed. A preferred approach employs proton transfer reaction mass spectrometry PTR-MS). The system may be operated continuously on a real time or near real time basis. A delivery tube of specific dimensions and materials is employed to introduce the sample into the ionization chamber which in turn generates the ions which are delivered to the mass spectrometer for determining the m/z values. The system may employ a plurality of ionization chambers to reduce the amount of false negative identifiers. A multiple inlet ion funnel may be employed to combine the ions from each of the ionization chambers. Chemical ionization may be employed. A validation module may be employed to reduce the amount of false positive identifiers.
