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.
Claims10
A method of performing electrochromatography, the method comprising the steps of:
- positioning a sample plate in a plate holder;
- positioning a frame member in contact with the plate holder to form an assembled plate holder;
- positioning the assembled plate holder between a pair of die blocks;
- urging a die block of the pair of die blocks with a ram through an opening defined in the body of the frame member toward a stationary phase supported on the 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.
