Abstract: There is provided a content determination assistance system capable of efficiently assisting in identifying a mixture that is highly likely to be contained in a sample. The content determination assistance system records characteristic mass spectrum data for each of known compounds. The content determination assistance system extracts the corresponding current-sample mass spectrum from the current-sample mass spectrum data, and detects a high intensity mass spectra from the corresponding current-sample mass spectrum. The content determination assistance system outputs a degree of concordance in the mass spectrum between a known compound subject to determination and a current sample using the characteristic mass spectrum and the high intensity mass spectrum.

Abstract: A sample crushing device is provided having a function of stably absorbing vibration of a support member supporting a sample container and vibration of other members which accompanies the vibration. When a rotating shaft 20 is rotated and driven by rotation driving mechanism, revolving motions of a first support member 12 around an axis line C1 of a rotating shaft 20 and rotational movement of an inclined shaft 10 around an axis line C2 arm restrained by a base 1 via first elastic members 14. As a result, the first support member 12 and sample containers 41 are vibrated in plural directions, and samples housed in the sample containers 41 are crushed by crushing media. Vibration of the first support member 12 in plural directions is absorbed by a base 1 via the first elastic members 14 coupled with each of the first support member 12 and the base 1.

Abstract: An unknown polymer is pyrolyzed by a pyrolizer and a produced mixture of pyrolytic products is separated into the pyrolytic products by a separating column. The separated pyrolytic products are detected by a mass spectrometer to generate a chromatogram. Ion intensities contained in all total ion intensities making up peaks in the chromatogram are added, for each ion of the same mass, to plot a combined mass spectrum of the unknown polymer. Combined mass spectra of a plurality of known polymers are generated in the same manner as with the combined mass spectrum of the unknown polymer, and stored as a library. The library is searched for the combined mass spectrum of one of the known polymers which agrees with a high probability percentage with the combined mass spectrum of the unknown polymer.

Abstract: A sample concentration device is provided in which a gaseous sample is concentrated by cooling a portion of a gas transfer line through which the sample is introduced into a detecting apparatus, such as a gas chromatograph or the like. The device is characterized by a cooling device for cooling a portion of the gas transfer line, which is housed in a constant temperature chamber, by spraying a coolant from a nozzle facing the portion of the gas transfer line, and by a gas flow device for creating a substantially dry gas flow through the nozzle to prevent the nozzle from becoming plugged with ice formed by freezing of moisture in the air inside the constant temperature chamber when the coolant spray is stopped. An outer jacket surrounding a portion of the gas transfer line which is subjected to cooling is also disclosed.
