Research and quality control laboratories benefit from NIRS alike. While researchers can accelerate their experimentation, QC departments benefit from the ability to analyze hundreds of samples per day – both saving substantial amounts of time and money.
The heart of the interferometer consists of two bi-refringing crystal wedges. By moving one wedge, a part of the light undergoes a phase shift. This phase shift alters the polarization of the entire beam. After passing a polarization filter the interferogram is detected. All wavelengths are measured simultaneously.
While the number of parameters measurable within a calibration model is only limited by computing power and complexity of the analysis, it is common to analyze 15-30 properties at the same time.
