The "Eye Dropper Size" determines the number of pixels TLC Analyzer averages together to form a single point in the resulting line graph. The left and right margins are then chosen (shown at 5 pixel margins, respectively). The user loads a digital image and then chooses what row(s) in the picture to scan (shown at row 890). The image used in this example is mainly green so the corresponding graph shows high green values, relatively low blue and K values, and almost 0 red values.Ī screen shot of TLC Analyzer. The brightness of the pixels is also graphed and is represented by the K-value. A graph is produced at the bottom-left of the program window that shows the red, green and blue pixel values of the scanned portion of the image. To the right of the image, options are available to change the image margins, scan row and eye dropper size which allows a user to analyze a specific portion of the image. For this purpose, TLC Analyzer is much easier to use and quicker than a photo-editing program.Ī screenshot of the program TLC Analyzer shows an image loaded into the top half of the program window. Thus, a digital image is essentially a matrix of numbers, and TLC Analyzer "virtually" pans across the matrix, combining moving averages to create a graph.
In contrast, a digital image is made up of many rows and columns of "dots" called pixels. TLC scanners pan across an HPTLC plate with a beam of light emitted through an adjustable slit. IntroductionĮssentially, TLC Analyzer is a simulated TLC scanner.

On this webpage you can download and learn how to use the software that enables DE-TLC: TLC Analyzer. Since this technique is less expensive than other quantitative chromatographic methods, DE-TLC is ideal for high school and college labs. Digitally enhanced TLC is a valuable tool that can be added to every chemist's TLC toolbox. Then, on a computer, using either TLC Analyzer, the public domain software written for this work, or common photo-editing software, one can quickly produce multi-spectral scans, densitograms, and calibration curves-output previously available only from more expensive equipment or complex procedures. A fluorescent TLC plate is illuminated with UV light and a picture of the plate is taken with a digital camera. This novel, digitally enhanced TLC (DE-TLC) is easy to use. If digital photography is combined with regular TLC, it can perform highly improved qualitative analysis as well as make accurate quantitative analysis possible. Unfortunately, HPTLC requires expensive equipment that most high schools and colleges cannot afford.
The more accurate high-performance TLC (HPTLC) is better suited for quantitative analysis.
