Chromatography

Chromatography is a technique for separating the components in a complex mixture. The mixture flows though a medium and the individual substances that make up the mixture are deposited at different distances from the point of inflow. In contemporary chemistry the resulting image is incidental and largely ignored. The emphasis there is on analysis of the types and amounts of the components.
In biodynamics the technique was originally named capillary dynamolysis and is used to create a picture of the substance that can be interpreted directly. Approached in this way it can reveal something of the inner nature of a substance - its vitality and dynamics.

Below are a number of chromatograms I have made of different substances. In making these images, I followed the procedure and recommendations of E.E. Pfeiffer described in "Chromatography Applied to Quality Testing" 1984, Bio-Dynamic Literature, Wyoming, USA.

Essentially, a circular filter paper (Whatman #1) with a cylindrical paper wick sitting in a 0.5% solution of silver nitrate is allowed to absorb the solution, which spreads by capillary action, to a certain diameter. The wick is removed and the paper is dried. Meanwhile, the substance to be tested is mixed with a 0.1 to 1% solution of sodium hydroxide and let stand for a period of time. The prepared filter paper is then allowed to absorb this solution and the substance spreads over the paper. When it has spread to a certain distance, the wick is removed and the paper dried. The paper is then exposed to indirect sunlight to let the image develop.
