<p>Provided is a polymer sample analyzer from which chemical findings on the optical deterioration of a polymer material are available in a very short time. The analyzer is equipped with a gas phase component production unit for producing a plurality of gas phase components, a carrier gas introduction unit for introducing a carrier gas into the gas phase component production unit, a separation unit for separating the gas phase components into each component, and a detection unit 5 for detecting the each component thus separated. The analyzer is equipped further with a UV irradiation unit for exposing the polymer sample to UV ray, an atmospheric gas introduction unit for introducing an atmospheric gas into the gas phase component production unit and a gas switching unit for switching a gas to be introduced into the separation unit between the carrier gas and the atmospheric gas. Under the atmosphere of a gas introduced from the atmospheric gas introduction unit, the polymer sample is deteriorated and decomposed by exposure to UV ray from the UV irradiation unit. After deterioration and decomposition, a gas to be introduced into the separation unit 4 is switched to the carrier gas by the gas switching unit and the gas phase components are introduced into the separation unit by the aid of the carrier gas.</p> |
