    Abstract: A system (10) for detecting and analyzing chemical and biological constituents in a sample (12). The system (10) includes a spectrometer (18) for passively receiving emissions (22) from the sample (12) to detect the constituents therein. A cold device (28) is positioned within the field-of-view of the spectrometer (18) at an opposite side of the sample (12) from the spectrometer (18). The cold device (28) provides a low temperature background relative to the sample (12) so as to increase the emissions (22) from the sample (12) and also to reduce the background emission. The system may further comprise a sample chamber (14) for containing the sample. Alternatively, the system may comprise a transmission sample window onto which the sample is provided or the system may be arranged for remotely investigating a sample cloud in the free atmosphere.

    Abstract: The present invention relates to a new analysis method to determine chemical compositions and states of metal materials. It includes the continuous steps of: using metallic discharge electrodes to perform the continuous spark discharge on the sample which is moved relative to the electrodes; dispersing the excited spark spectrum to form the linear spectrum with preset wavelength; recording the positions of every single spark discharge and the spectrum signals rapidly and at real-time; transferring the spectrum signals into electrical signals which are then inputted into signal memory; using a computer to statistically analyze the linear spectrum obtained from the single spark discharge, by which the distribution of chemical compositions, segregation, porosity and inclusion in the sample are resulted and then outputting these results. According to the present invention, the sample is subject to continuous excitation and synchronous scanning without pre-sparking, and every single spark spectrum signals is rapid collected and digital analyzed. Thus the original state of inclusion in sample without re-melting is obtained and various parameters for elements in sample, such as chemical compositions, segregation, porosity and inclusion content and distribution of these parameters are able to be simultaneously determined with one time scanning.
