The Samuel Roberts Noble Foundation, Inc.   Near infrared spectroscopy aiding scientists' efforts; workshop set
 

Near infrared spectroscopy (NIRS) sounds like science fiction. In reality, this technologically advanced tool is shaping how scientists gather and verify information.

Near infrared spectroscopy uses a particular band of infrared light. This light is shone on an object or a substance, and reflections are then interpreted using computers performing high speed calculations. The result: the reflection from the infrared light reveals the composition of the substance.

Scientists at The Samuel Roberts Noble Foundation use NIRS to estimate protein and fiber content, digestibility and nutritional information of forage samples. The Noble Foundation agricultural consultants can also use the test results to develop livestock feeding programs for farmers and ranchers.

Likewise, researchers in the medical industry can scan unknown compounds and determine their chemical makeup. Commercial candy companies, such as Hershey's, use the technology as a quality control method, scanning outgoing chocolate to make sure it possesses similar consistencies.

"It sounds a bit like magic," said Andy Hopkins, Ph.D., principal investigator at the Noble Foundation. "However, the results have been confirmed by chemical tests in the laboratory."

While these chemical tests can produce the desired results, near infrared technology is quicker and far cheaper, enabling researchers to expand their information gathering efforts.

"We can assemble a large amount of data in an efficient manner," Hopkins said. "In my research, we're looking at improving digestibility in particular forages. So if I have the capability of examining 10,000 samples instead of just several hundred, then I'm more confident in my findings. Additionally, we can forgo the extensive cost of performing the same work in the laboratory."

To help standardize and coordinate the use of infrared instrument, almost 40 universities and private laboratories nationwide formed the Near Infrared Spectroscopy Consortium (NIRSC). The Noble Foundation will host a workshop for the NIRSC from Monday, Aug. 11, to Wednesday, Aug. 13, at its Ardmore campus.

The workshop will allow new members and nonmembers to learn more about the consortium and how to utilize its resources. Attendees also will have the opportunity to learn about various NIRS platforms.
