QCLAS and CRDS-Based CO Quantification as Aimed at in Breath Measurements
Figure 9
CO R(12) line measured with the cw-QCL CRDS setup on mixtures of 100 nmol/mol and 10 nmol/mol CO in nitrogen, respectively, at 1000 hPa total pressure. The straight lines are Lorentz profiles fitted to the experimental data (a). (b) Measured spectrometric amount fraction results compared to gravimetric reference values.
