Near-Infrared Spectroscopy Imaging

FIGURE 31.17 Near Infrared Spectroscopy images depict the change in skin hydration state one hour after water wash versus a wash with an emollient BW. The increase in dark areas indicate greater hydration after washing with the emollient BW. The change in hydration state for a lotion treated site is included for reference.

Near-infrared chemical imaging instrumentation is rugged and flexible, suitable for both the laboratory and the manufacturing environment. Therefore analysis methods developed in the laboratory can often be tailored for implementation near-line or at-line. NIR-CI is also a massively parallel approach to NIR spectroscopy, making the technique well suited for high-throughput applications.

Near-infrared chemical imaging using multichannel detectors inherits many of the attributes of conventional NIR spectroscopy using a single-channel detector. In addition to its well-documented capabilities as a spectroscopic technique, in comparison to other vibrational imaging approaches, it has unparalleled flexibility in terms of managing widely varying sample size, placement, shape and color. As has been shown with the three examples presented in this chapter, the technique easily...
