The NIRS DA1650 is a Diode array (DDA) based NIR reflectance and transflectance analyser with a scanning range of 1100 – 1650 nm. Beyond 1650nm, DDA technology becomes quite unreliable. That is why we chose to limit the wavelength range of the NIRS DA1650 to a maximum of 1650nm, and because we also know that going beyond 1650nm will not have a dramatic impact on your results accuracy and repeatability.
The wavelength gives accurate results for standard parameters such as protein and moisture and ash. If however, you want to achieve the ultimate in measurement of ash, consider also the NIRS DS2500 Flour analyser, see here. This operates on a broader wavelength using monochromator technology giving great results for ash and specialty parameters such as colour.
Practical DDA technology
DDA technology is highly practical and low maintenance, for example, changing the lamp used in the instrument does not require any intensity correction. The NIRS DA1650 also provides internal standards in order to automatically control the stability of the spectrometer with time, which makes this instruments very low maintenance overall.
Calibrations can also be transferred to a process control solution such as ProFoss also based on DDA.
