In thin layer chromatography, two sheets of sheet are pressed to join the binder
Drop method that is used to filter paper or gauze will spread to the upper end of the absorbent plate, so that the agent along the plate down, this method is suitable for the continuous development of small Rf value of compounds; two-dimensional chromatography sample points in the corner of the square plate, first launched in one direction, then the rotation angle of 90 degrees the position, then another agent spread out, suitable for the separation of complex compounds.
And the expansion way of soft board without adhesive is inclined 10 - 15 angle upward method.
The difference between an adhesive and an adhesive in the test is that the chromatographic plate with adhesive is expanded by the rising method, about which the plate is perpendicular to the container with an expanding agent and the inclination is 45 to 60 degrees upward;
