Abstract
This application discloses cards comprising sintered porous plastic which may be employed in liquid sample collection, storage, transport and/or delivery to an analytical device. Sintered porous plastic materials provide a unique porous structure, an inert substrate, precise liquid holding capability, are quick drying, and easy to cut and handle.
Claims22
A card for receiving a liquid sample, the card comprising:
- (a) at least one sintered porous plastic liquid sample receiving spot;
- and
- (b) a non-porous non-sample receiving region surrounding the at least one liquid sample receiving spot.
-17. (canceled)
A method for liquid sample collection, storage, transport, and/or delivery to an analytical device comprising:
- providing a card comprising at least one sintered porous plastic liquid sample receiving spot and a non-porous region surrounding the at least one liquid sample receiving spot;
- applying a liquid sample to the at least one liquid sample receiving spot;
- removing at least a portion of the at least one liquid sample receiving spot from the card;
- and,
- storing the removed portion of the liquid sample receiving spot, transporting the removed portion of the liquid receiving spot or delivering the removed portion of the liquid sample receiving spot to an analytical device.
2 more elements
