ABSTRACT:
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 unit5for 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 unit4is 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.
