===Infrared absorption===
Sugars also have known [[infrared]] absorption spectra and this has made it possible to develop instruments for measuring sugar concentration using mid-infrared (MIR), [[Nondispersive infrared sensor|non-dispersive infrared]] (NDIR), and [[Fourier-transform infrared spectroscopy|Fourier transform infrared]] (FT-IR) techniques. In-line instruments are available that allow constant monitoring of sugar content in sugar refineries, beverage plants, wineries, etc. As with any other instruments, MIR and FT-IR instruments can be calibrated against pure sucrose solutions and thus report in °Bx, but there are other possibilities with these technologies, as they have the potential to distinguish between sugars and interfering substances. Newer MIR and NDIR instruments have up to five analyzing channels that allow corrections for interference between ingredients.
