Abstract:
An extraction apparatus includes extraction fluid sources (9), modifying agent source (3), extraction cartridges (2) with extraction chambers (1), and collection vessels (13) connected by tubing and multiport valves (16, 17, 18, 19, 20, 21) for ease of automation.
Abstract:
The invention relates to reagents, methods, devices and systems for comminuting, extracting and detecting drug, pesticide, herbicide and steroid analytes in solid biological samples originating e.g. from man, domestic animals, plants, amphibians, insects and reptiles.
Abstract:
An apparatus for comminuting biological specimens includes a receiving component (12) provided with a drive source (16, 18), a sample retainer (52) configured for retaining at least one biological specimen and for engagement in the receiving component, and a single use comminution mechanism (66, 68, 70) in operational relationship with the sample retainer. The drive source is configured for driving the comminution mechanism. A collector (42) is associated with the receiving component (12) for receiving comminuted product generated by the comminution mechanism.
Abstract:
A transportable automated analyte extraction apparatus is provided which includes at least an extraction fluid supply in communication with an extraction chamber, and a collection vessel in communication with the extraction chamber, wherein the extraction chamber includes a sample cartridge. The analyte extraction apparatus preferably utilizes supercritical extraction fluids and a modifying reagent, collectively called the extraction solution, to extract analyte from a sample. The extracted analyte can then be subjected to subsequent testing.
Abstract:
An apparatus (10) for comminuting biological specimens includes a receiving component (28) provided with a drive source (30), at least one sample retainer (26) configured for accommodating at least one biological specimen and constructed and arranged for engagement in the receiving component. The sample retainer (26) includes a first component (80) configured for receiving a specimen prior to comminution and a second component (96) for receiving the specimen after comminution. In addition, the sample retainer (26) is insertable into the receiving component (28) as a single piece.
