Light reflectance measurements in the near-infrared region are being developed to measure several non-cellulosic components in cotton. A newly developed filter-type spectrometer is sufficiently fast enough to inspect cotton while it is being graded for market. After selecting several filters to measure total sugars and other filters for stickiness, the new instrument method predicted total sugars within 0.13% and white fly insect stickiness within 0.5 minicard units.
