ABSTRACT:
A plurality of molecule components included in a gas are to be ionized at the same time by PI method. For instance, a plurality of molecule components included in a gas generated at a certain instance are accurately analyzed in real time based on PI method. A gas analyzer is provided with a gas transfer apparatus for transferring a gas generated from a sample in a sample chamber to an analyzing chamber; an ionizer for ionizing the gas; a quadruple filter for separating ions by mass/charge ratio; and an ion detector for detecting the separated ions. The ionizer is provided with an ionizing region arranged in the vicinity of a gas exhaust of the gas transfer apparatus, and a lamp for applying light on the ionizing region. Since the lamp outputs light which has light directivity lower than that of a laser beam and travels by spreading, the gas entered the ionizing region in the ionizer receives light in a wide range, and the gas components inside are ionized at the same time.
