Quantum Cascade Laser Infrared Spectroscopy for Online Monitoring of Hydroxylamine Nitrate

Figure 4

Calibration curves for hydroxylamine nitrate using the QCL-ATR system. The response was very similar for the peaks at 3.77 and 7.46 μm, with the latter giving better linearity. The sensitivity at 9.81 μm was half that seen at the shorter wavelengths.
