Use of the software processing of scanned chromatogram images in quantitative planar chromatography

The results of quantitative TLC analysis using the software processing of scanned chromatogram images are demonstrated by the example of the separation and determination of food dyes. The chromatograms obtained were digitized by scanning with a flatbed scanner. Quantitative analysis was performed using special-purpose software. The use of the software processing of scanned images does not require expensive analytical C, instruments and provides an unbiased quantitative evaluation of substances in a chromatographic peak with a minimum of time expenditure.
