08/02/2015: NIR speed improves with introduction of dynamic sub-sampling

The use of Near Infra-red transmittance analysis techniques, as used by the FOSS Infratec™ 1241, has become a standard for whole grain analysis at the point of receival.

One key to the success of this technique has been the speed of the analysis allowing a sample to be analysed in around one minute. A second success factor has been the ability to analyse a relatively large sample compared to alternative techniques. This is achieved through analysis of multiple sub-samples combined with mathematical averaging of results to provide a robust prediction of the results.

Increasing the number of sub-samples has been shown to improve the repeatability of a measurement.

Conversely, reducing the number can have the opposite effect. In other words, the effect of sub-sampling with homogeneous samples is negligible whereas with inhomogeneous samples, the sub-sampling is critical.

Speed remains a critical element of efficient grain receival and any gains that can be made can improve overall efficiency of the operation. With sub-sampling being one of the contributors to overall analysis time, the opportunity to reduce these where possible - without impacting accuracy - is a useful improvement that can add value to a grain company.
