How does it work
The principle of spectroscopy is to expose a sample to polychromatic radiation.
This causes vibrational excitation of covalent bonds in the molecules present in the sample. Each molecule has a unique fingerprint of absorption as the various molecular bonds only can absorb very specific frequencies and amounts of energy.
SIBA records the reflected spectra in-line in a loop from the mash tank and through a unique multivariate calibration complex it determines and provides a full profiling of the molecules present in the mash, including the key parameters needed by the brewers to control the mashing process.
SIBA operates in the Mid infrared area (MIR) where the first order excitation of the key molecules of the mashing process occurs.
SIBA thus provides very accurate measuring results.
A systems operating in the Near infrared area (NIR) would only give rise to excitation of second or third orders in the key molecules of the mashing process. This would only provide sketchy and uncertain information of the molecular presence of no use to the analyses of the mashing process.
