Thin-layer chromatography is a standard laboratory method in chemistry used to identify compounds, assess purity and track a reaction’s progress. It involves an adsorbent film on a glass plate or other carrier on which samples of interest are placed. As the components of the sample travel through the film, they separate, enabling analysis. The problem is that scanning densitometry, the standard measurement technique used with thin-layer chromatography, has some drawbacks. In densitometry, a light typically diffusely reflects off a plate and into a detector, quantifying absorbance and...Read full article

    chromatography
    The chemical method of separating compounds dissolved in one phase (usually mobile) through its equilibration with a second phase (usually stationary). The mechanism of separation may involve partition, adsorption, permeation or exclusion, or ion exchange.
    densitometry
    The detection and analysis of the transmission and reflection properties of objects and photographic images.
    digital camera
    A camera that converts a collected image into pixels that are black or white digital or shades of gray. The digital data may then be manipulated to enhance or otherwise modify the resulting viewed image.
