A thin-layer chromatography method for identifying material present in a sample on a location including the steps of provide a thin-layer chromatography plate, wetting a swab is with a solvent providing a wetted swab, contacted the location of interest is with the wetted swab to obtain the sample providing a wetted swab with sample, placing the wetted swab with sample in the solvent to dissolve the sample and provide a solvent with sample, dipping a micropipette into the solvent with sample to obtain an amount of the solvent with sample, spotting the amount of the solvent with sample on the thin-layer chromatography plate, allowed the amount of the solvent with sample on the thin-layer chromatography plate to dry providing a thin-layer chromatography plate with sample, placing the a thin-layer chromatography plate with sample into a developing chamber with solvent mixture, allowing the thin-layer chromatography plate with sample to develop producing a developed thin-layer chromatography plate with sample, removing the developed thin-layer chromatography plate with sample from the developing chamber, and illuminating the developed thin-layer chromatography plate with sample with ultra violet light to produce an image for identifying the material present in the sample.
