A simple theoretical model correctly predicts the dependence of the CO signal on chopping frequency and concentration dependence but is inadequate in describing the pressure dependence. Concentrations as low as 50 ppmv were measured by operating the cell in a double pass mode. </jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1383670318680988545","@type":"Researcher","foaf:name":[{"@value":"T.
