Katerine Loaiza and Érika Giraldo are in charge of the process of validation of the new NIRS in the FLAR’s Rice Quality Laboratory.

Modern, friendly, efficient and with an immediate results report, the NIRS ™ DS2500 (1) is incorporated into the FLAR’s Rice Quality Laboratory as one of the equipment that will provide more complete quality analysis results, in less time, to different research programs of the International Center for Tropical Agriculture (CIAT, by its Spanish acronym) and FLAR member countries.


Since the creation of FLAR, we have been working together with CIAT for the constant improvement of the Rice Quality Laboratory, an effort that has resulted in the acquisition of equipment that allows us to expand the evaluation capacity of rice lines and hybrids. Eighteen years ago, the NIRS ™ System 6500 enabled a jump in the capacity of assessment of amylose content, from colorimetric analysis (a manual method) to the near-infrared spectroscopy methodology offered by the NIRS. This meant an increase in the precision and the number of samples analyzed daily, as well as the reduction in the emission of chemical wastes, necessary with the colorimetric method.


With the arrival of the NIRS ™ DS2500, we take a new leap in rice quality analyzes that will be of great help to the FLAR Rice Breeding Program as well as to other CIAT research programs. Katerine Loaiza, Coordinator of the FLAR’s Rice Quality Laboratory, explained some advantages of this new tool.


Benefits of the NIRS ™ DS2500

Although the NIRS™ System 6500 and the NIRS™ DS2500 share Near Infrared Reflectance technology, the latter represents advances in terms of sample analysis time, increased power, accuracy, and performance. Also, advances in the robustness of the instrument, allow a high performance, even in the harshest conditions of production (humidity, dust, vibrations, and temperature fluctuations).


But perhaps where the greatest benefit of the NIRS ™ DS2500, as Katerine Loaiza indicates, is in the calibration of the equipment. “This instrument allows us, besides making calibrations in flour, to use the sample of brown rice. This represents a more efficient use of time for the preparation of the sample, since in this case it is not necessary to peel, polish and mill the grain. “


The new acquisition, obtained thanks to the investment of CIAT and FLAR, also offers advantages in obtaining results, since the software that supports it generates a report of results in real time and allows the visualization of graphs, analysis of trends and the storage of a greater number of Spectra.

Projections of use

Even though the NIRS™ DS2500 is already installed in the FLAR’s Rice Quality Laboratory, the incorporation of this new technology requires a validation period that will start in 2017 and will include the use of both NIRS instruments simultaneously .


This tool will also be available for other CIAT programs, such as HarvestPlus, to assist in the nutritional analysis of biofortified crops, and the Tropical Forage Program.
