Abstract
Kits and processes for detecting analytes present in solid materials, especially soil or foodstuffs. The kits and processes utilize a tubular apparatus, fitted or fittable with a piston, cap and filter, as a scoop and both to extract the analyte from the solid material into the extraction liquid and to separate the extraction liquid from the solid material.
Claims18
A process of extracting an analyte from a sample of solid material, said process comprising the steps of:
- 1) scooping solid material into, the open end of a tubular device using the tubular device as a scoop, said tubular device being fitted with a piston,
- 2) contacting the solid material with an extraction liquid, and
- 3) separating the extraction liquid from the solid material by filtration, wherein steps (1), (2), and (3), are done in a chamber inside the same tubular device, wherein for step (2) said chamber is sealed to prevent leakage of liquid and wherein for step (3) said tubular device comprises a filter at one end and a piston at the other end so that movement of the piston towards the filter will push the liquid but not the solid material through the filter thereby separating the liquid from the solid material.
