The basic idea of this technique is that the absorption process of molecules by laser irradiation is monitored as the pressure enhancement in a gas cell by use of a differential pressure gauge. The system is composed of a tunable IR laser system, sample cell, differential pressure gauge, and data accumulation system. Using this system, the measurements of the IR absorption spectra for cyclohexane (50 ppm) and ammonia (100 ppm) are demonstrated. By comparison of the current IR-DP spectra with conventional Fourier-transform infrared spectra, the spectral resolution is found to be about 3 cm−1, reflecting the laser resolution. Furthermore, the estimated pressure enhancement based on a simple model is consistent with the experimental results. These results suggest that the newly developed IR-DP technique is one of a powerful tool for trace gas detection.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_1617186643794":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_publisher":"AIP Publishing","subitem_publisher_language":"en"}]},"item_1617186702042":{"attribute_name":"Language","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_1617186901218":{"attribute_name":"Funding Reference","attribute_value_mlt":[{"subitem_award_numbers":{"subitem_award_number":"20H02691","subitem_award_uri":"https://kaken.nii.ac.jp/grant/KAKENHI-PROJECT-20H02691/"},"subitem_award_titles":[{"subitem_award_title":"反応遷移状態における励起化学種の構造制御による反応分岐発現機構の解明","subitem_award_title_language":"ja"},{"subitem_award_title":"Control of branching ratio of reaction products by regulating the orientation of reactive complex in the transition state","subitem_award_title_language":"en"}],"subitem_funder_identifiers":{"subitem_funder_identifier_type":"Crossref Funder","subitem_funder_identifier_type_uri":"https://doi.org/10.13039/501100001691"},"subitem_funder_names":[{"subitem_funder_name":"日本学術振興会","subitem_funder_name_language":"ja"},{"subitem_funder_name":"Japan Society for the Promotion of Science","subitem_funder_name_language":"en"}]},{"subitem_award_numbers":{"subitem_award_number":"22K19047","subitem_award_uri":"https://kaken.nii.ac.jp/en/grant/KAKENHI-PROJECT-22K19047/"},"subitem_award_titles":[{"subitem_award_title":"超微差圧計測システムによる新規ガス分析装置の開発と生体ガス分析への応用","subitem_award_title_language":"ja"},{"subitem_award_title":"Development of new gas analyzer using differential pressure measurement system and its application to biogas analysis","subitem_award_title_language":"en"}],"subitem_funder_identifiers":{"subitem_funder_identifier_type":"Crossref Funder","subitem_funder_identifier_type_uri":"https://doi.org/10.13039/501100001691"},"subitem_funder_names":[{"subitem_funder_name":"日本学術振興会","subitem_funder_name_language":"ja"},{"subitem_funder_name":"Japan Society for the Promotion of Science","subitem_funder_name_language":"en"}]}]},"item_1617187056579":{"attribute_name":"Bibliographic Information","attribute_value_mlt":[{"bibliographicIssueDates":{"bibliographicIssueDate":"2024-12","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"12","bibliographicPageStart":"125106","bibliographicVolumeNumber":"95","bibliographic_titles":[{"bibliographic_title":"Review of Scientific Instruments","bibliographic_titleLang":"en"}]}]},"item_1617258105262":{"attribute_name":"Resource Type","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_1617265215918":{"attribute_name":"Version Type","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_1617353299429":{"attribute_name":"Relation","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1063/5.0234925","subitem_relation_type_select":"DOI"}}]},"item_1617605131499":{"attribute_name":"File","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2025-05-26"}],"filename":"RevSI_95_125106.pdf","filesize":[{"value":"1021 KB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"objectType":"fulltext","url":"https://hiroshima.repo.nii.ac.jp/record/2040655/files/RevSI_95_125106.pdf"},"version_id":"53a0e8b9-5789-461f-89cc-835efe34f51c"}]},"item_title":"Development of new gas analytical technique for infrared spectroscopy combined with differential pressure measurements","item_type_id":"40036","owner":"7","path":["1730444907710"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2025-05-26"},"publish_date":"2025-05-26","publish_status":"0","recid":"2040655","relation_version_is_last":true,"title":["Development of new gas analytical technique for infrared spectroscopy combined with differential pressure measurements"],"weko_creator_id":"7","weko_shared_id":-1},"updated":"2025-05-26T04:05:21.284146+00:00"}
