    • 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.
    • 包含在气体中的多个分子成分将通过PI法同时离子化。 例如,在某种情况下产生的气体中包含的多个分子成分可以基于PI法实时准确分析。 气体分析装置具备:气体传送装置,用于将样本室中的样品产生的气体转移到分析室; 用于离子化气体的离子发生器; 用于通过质量/电荷比分离离子的四重滤波器; 以及用于检测分离的离子的离子检测器。 电离器设置有布置在气体传送装置的排气附近的电离区域和用于在电离区域上施加光的灯。 由于灯输出光指向性低于激光束的光并通过扩展而行进,所以进入离子发生器中的电离区域的气体接收到宽范围的光,同时内部的气体成分被离子化。
