Chromatographic medium
09726650 · 2017-08-08 · ·

A chromatographic medium having a separating agent layer, which is used to separate target substances, a filling agent layer, which is used to fix the target substances before the target substances are separated, and a permeation layer, which is used to enable permeation of the target substances separated by the separating agent layer, wherein the filling agent layer comes into contact with the separating agent layer via a plane that intersects the direction of development of the target substances in the chromatographic medium and is positioned on the upstream side in the direction of development, the separating agent layer exhibits separability of the target substances and optical responsiveness to ultraviolet rays, and the permeation layer exhibits an optical responsiveness that is different from those of the target substances and the separating agent layer.

Method and apparatus for automatic chromatography of thin-layer plates

A method for the automatic chromatography of thin-layer plates for thin-layer chromatography with a development chamber 1 in which a thin-layer plate D is completely enclosed, sealed-off and isolated from the external environment. In the development chamber, a front space containing an inner atmosphere is located on the front face of the separation layer of the thin-layer plate. The depth of the front space is about 2 mm and a maximum 3 mm. An inlet is provided at one end of the front space and an outlet is provided at the other end of the front space. During the chromatographic development, a stream of gas of particular composition determined by the user is created throughout the entire front space, the entire inner atmosphere being set in motion, without stagnant or stationary gas phase.

METHOD AND SYSTEM FOR SOLVENTLESS CALIBRATION OF VOLATILE OR SEMI-VOLATILE COMPOUNDS

A system for solventless calibration of volatile or semi-volatile compounds and methods thereof. The system includes a fluid path having a first end configured to be operably coupled to a fluid source and a second end configured to be operably coupled to the analytical instrument. A solid sorbent is disposed along the fluid path and is configured to absorb an analyte. The flow of fluid along the fluid path from the first end to the second end causes absorbed analyte to be desorbed from the solid sorbent at a desired concentration to the instrument.
