Paper chromatography is one of several chromatographic methods that is used in the laboratory to separate various components of a mixture. The mixture is place at the origin of the paper strip, and then solvent is allowed to flow up/down the paper strip via capillary action. As the solven migrates, so do the various components of the mixture, but they do so at different rates, depending on their solubility in the solvent and their affinity for the paper.

Interestingly the watch's papers mention ref. 101.027X link the "secret reference" L1 with a white gold case and silver dial secret because Lange link never publicized it and not the typical steel Lange 1 ref. 101.026. The entire package is an interesting piece of Lange history but in the end a steel Lange 1 is a steel Lange 1 which is to say an extremely rare watchmost estimates put production link at about 30 pieces.
