Patent ID: 6937695

Claim:
An analyzing apparatus comprising: a small-angle X-ray scattering device that can detect X-rays scattered at a small angle to an axis of an X-ray applied to a sample, wherein the small-angle X-ray scattering device comprises: an X-ray source for generating X-rays, an X-ray collecting means for focusing X-rays at one point, and a two-dimensional X-ray detector for detecting X-rays at various points in a plane; a mass spectrometer capable of measuring the mass number of gas generated by the sample; sample-holding means for holding the sample at a position which is common to the small-angle X-ray scattering device and the mass spectrometer, wherein the sample-holding means is connected to provide the gas generated by the sample to the mass spectrometer using a carrier gas; sample temperature-controlling means for controlling a temperature of the sample; and control means for controlling the small-angle X-ray scattering device and the mass spectrometer, causing the same to detect the X-rays and analyze the gas generated by the sample at the same time.
