Abstract
According to one aspect of the disclosure, there is provided an apparatus (210) for performing electrochromatography. The apparatus (210) includes a die block (222) which is movable to exert a pressure greater than atmospheric pressure on a chromatography sample plate during performance of an electrochromatography procedure. A method of performing electrochromatography is also disclosed.
Claims47
A method of performing electrochromatography, the method comprising the steps of:
- urging a die block toward a stationary phase supported on a sample plate so as to exert a pressure which is greater than atmospheric pressure against the stationary phase, and
- creating an electrical potential across the stationary phase with a first electrode and a second electrode so as to cause a liquid mobile phase to be advanced across the stationary phase.
An apparatus for performing electrochromatography, the apparatus comprising:
- a plate holder configured to support a sample plate, and
- a die block, at least one of the die block and the plate holder being movable relative to the other so as to exert a force which is greater than atmospheric pressure on the sample plate when the sample plate is positioned in the plate holder.
An apparatus for performing electrochromatography, the apparatus comprising:
- a plate holder configured to support a sample plate,
- a first die block, and
- a second die block, the first die block and the second die block being movable relative to one another so as to exert a force which is greater than atmospheric pressure on the sample plate when the sample plate is positioned in the plate holder.
An apparatus for performing electrochromatography, the apparatus comprising:
- a plate holder configured to support a sample plate,
- a die block, at least one of the die block and the plate holder being movable relative to the other so as to exert a force which is greater than atmospheric pressure on the sample plate when the sample plate is positioned in the plate holder, and
- a thermally conducting, electrically insulating sheet positioned between the die block and the plate holder.
An apparatus for performing electrochromatography, the apparatus comprising:
- a sample plate, and
- a die block, at least one of the die block and the sample plate being movable relative to the other so as to exert a force which is greater than atmospheric pressure on the sample plate.
