In the near infrared region of wavelengths 1.1 to 2.5 μm, there is absorption by OH groups in water (1.45 μm band, 1.9 μm band) and absorption by CH groups of alcoholic beverages (2.1 to 2.5 μm). With transmission measurement results, we were able to obtain the characteristic spectr...
tab allows you to set up hardware checks during data collection – i.e.: it checks if water and CO2 levels are too high (no purge gas running), if there is ice buildup on the detector and so on. Should aproblem arise, you will get a “warning” during data collection. The ...

Peak overlap plagues conventional one-dimensional infrared spectroscopy. In contrast, two-dimensional infrared spectroscopy expands the peaks in two dimensions, improves spectral resolution by reducing the number of overlapping peaks, and establishes explicit assignments by means of correlation analyses of ban...
