Abstract
A method of processing a sample comprising introducing a sample into a flow-through device containing a porous solid media therein, and thereafter subjecting the device to microwave energy. Also disclosed is a flow through device including solid porous media therein and attached active components.
Claims26
A chromatography apparatus comprising
- a chromatography sample module comprising
- a flow-through member having an inlet and an outlet, and
- a media within said flow-through member, said media being spaced from said inlet, so that said flow-through member defines a receiving region adapted to receiving a head piece for making a seal with said flow-through member,
- said media including attached active components;
- a sample on said media,
- said sample including reagents that undergo a chemical reaction to form a reaction product through exposure to energy from an energy source;
- and
- a radiation energy source for emitting radiation energy.

A chromatography apparatus comprising
- a chromatography sample module comprising a tubular member that is sized to fit entirely within the end of a chromatography column containing a separation media carrying a sample, said module having an inlet and an outlet, and chromatography media within said tubular member and spaced from said inlet, so that said tubular member defines a receiving region adapted to receive a head piece, said tubular member sized to be sealed within said chromatography column with a sealing device used to seal said chromatography column,
- said chromatography media including attached active components;
- a sample on said chromatography media,
- said sample including reagents that undergo a chemical reaction to form a reaction product through exposure to energy from an energy source;
- and
- a radiation energy source for emitting radiation energy.
3 more elements
A chromatography apparatus comprising
- a chromatography sample module comprising
- a flow-through member having walls and having an inlet end and an outlet end;
- a media disposed within said flow-through member, said media being spaced from said inlet end so that said walls extend above said media and so that said flow-through member defines a receiving region adapted to receive a head piece;
- a sample carried on said media,
- said media including attached active components,
- said sample including reagents that undergo a chemical reaction to form a reaction product through exposure to energy from an energy source;
- and
- a radiation energy source for emitting radiation energy.
