Abstract: A headspace sampler includes: a sample gas collection channel whose one end communicates with a needle; a pressure gas introduction channel and an exhaust channel that communicate with the other end of the channel in parallel via a branching pipe; a pressure control device that delivers pressure gas to the pressure gas introduction channel at a predetermined pressure; solenoid valves provided in the pressure gas introduction channel and the exhaust channel, respectively; and switching means for switching a state where a measuring pipe is inserted in the sample gas collection channel and a state where the measuring pipe is shorted away from the channel, wherein a pressure sensor is provided on an upstream side of the solenoid valve in the exhaust channel.

Abstract: In a mass analysis data analyzing apparatus, centroid data is used as mass spectrum data to be analyzed. First, peaks on the centroid data are specified in order of intensity as a standard peak for identifying an isotopic cluster. The isotopic cluster is detected by comparing an emerging pattern of peaks near the standard peak and an emerging pattern of peaks of an expected isotopic cluster in the case where each valence is assumed. The valence of the determined isotopic cluster is set as the valence of the peaks belonging to the isotopic cluster, and the peak at the forefront of cluster is selected as a monoisotopic peak. With such a mass analysis data analyzing apparatus, it is possible to determine the valence of each peak and identify the monoisotopic peak in a mass spectrum.
