To accomplish this, a small resin reaction cell for the sample solution and acid (initiator for CO<jats:sub>2</jats:sub> liberation) was devised and placed in a commercially available air-tight glass container with a Petri dish to form a microdiffusion analysis unit. The analysis was based on the principles of the conventional manual titration method that uses Ba(OH)<jats:sub>2</jats:sub> as the CO<jats:sub>2</jats:sub> absorbent. Using the new device, 99.5% recovery, with a relative standard deviation of 4.5% (n = 8), was achieved in a test analysis for 0.03 mmol of CO<jats:sub>2</jats:sub> liberated from a Na<jats:sub>2</jats:sub>CO<jats:sub>3</jats:sub> solution as a simulated sample. The analytical performance of the new device was almost comparable to that of conventional units under the experimental conditions of this study. Applying this new device for analyzing fluid samples from volcanic areas will contribute to enhancing the performance by reducing the possibility of CO<jats:sub>2</jats:sub> contamination and by simplifying the process by eliminating the need for preparatory cleaning for fixative application.</jats:p>\n                <jats:p><jats:bold>Graphical Abstract</jats:bold></jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1380025431138055562","@type":"Researcher","foaf:name":[{"@value":"Muga Yaguchi"}]},{"@id":"https://cir.nii.ac.jp/crid/1380025431138055558","@type":"Researcher","foaf:name":[{"@value":"Takeshi Ohba"}]}],"publication":{"publicationIdentifier":[{"@type":"EISSN","@value":"18805981"}],"prism:publicationName":[{"@value":"Earth, Planets and Space"}],"dc:publisher":[{"@value":"Springer Science and Business Media LLC"}],"prism:publicationDate":"2024-11-11","prism:volume":"76","prism:number":"1"},"reviewed":"false","dcterms:accessRights":"http://purl.org/coar/access_right/c_abf2","dc:rights":["https://creativecommons.org/licenses/by/4.0","https://creativecommons.org/licenses/by/4.0"],"url":[{"@id":"https://link.springer.com/content/pdf/10.1186/s40623-024-02062-z.pdf"},{"@id":"https://link.springer.com/article/10.1186/s40623-024-02062-z/fulltext.html"}],"createdAt":"2024-11-11","modifiedAt":"2024-11-11","project":[{"@id":"https://cir.nii.ac.jp/crid/1040285300660745984","@type":"Project","projectIdentifier":[{"@type":"KAKEN","@value":"19KK0084"},{"@type":"JGN","@value":"JP19KK0084"},{"@type":"URI","@value":"https://kaken.nii.ac.jp/grant/KAKENHI-PROJECT-19KK0084/"}],"notation":[{"@language":"ja","@value":"フィリピン・タール火山におけるその場観測に基づくマグマシステムの発達過程の研究"},{"@language":"en","@value":"Understanding the magma system at Taal volcano, Philippines, based on in-situ geophysical observations"}]}],"relatedProduct":[{"@id":"https://cir.nii.ac.jp/crid/1360005744245266688","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["references"],"jpcoar:relatedTitle":[{"@value":"Time Variation in the Chemical and Isotopic Composition of Fumarolic Gasses at Kusatsu-Shirane Volcano, Japan"}]},{"@id":"https://cir.nii.ac.jp/crid/1360298755629672576","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["references"],"jpcoar:relatedTitle":[{"@value":"A Depression Containing CO2-Enriched Water at the Bottom of Lake Monoun, Cameroon, and Implications for the 1984 Limnic Eruption"}]},{"@id":"https://cir.nii.ac.jp/crid/1360306913836209536","@type":"Article","relationType":["references"],"jpcoar:relatedTitle":[{"@value":"The control and measurement of ‘CO2’ during fermentations"}]},{"@id":"https://cir.nii.ac.jp/crid/1362825895320243328","@type":"Article","relationType":["references"],"jpcoar:relatedTitle":[{"@value":"Long‐term variations of the Campi Flegrei, Italy, volcanic system as revealed by the monitoring of hydrothermal activity"}]},{"@id":"https://cir.nii.ac.jp/crid/1362825895670076800","@type":"Article","relationType":["references"],"jpcoar:relatedTitle":[{"@value":"Recent pH and CO2 profiles at Lakes Nyos and Monoun, Cameroon: implications for the degassing strategy and its numerical simulation"}]},{"@id":"https://cir.nii.ac.jp/crid/1363670318473699328","@type":"Article","relationType":["references"],"jpcoar:relatedTitle":[{"@value":"Formation process of recent fumarolic gases at the Mt.
