Ftir film thickness
WebFirstly, limited surface sensitivity (typical limit of detection is a film thickness of 100 nm) Only specific inorganic species exhibit an FTIR … Webused to produce a film of the desired thickness or pathlength. A constant pathlength is highly desirable when performing quantitative analyses. Overall, sample preparation is easier for liquid transmission studies when compared to solid transmis-sion sampling but both suffer from inevitable reproducibility issues given the complexity of the sample
