?:definition
  • Automated laboratory samplers designed to extract organic samples from solid materials using solvents at high pressure and temperature. These samplers typically include an extraction cell, pump, high-pressure gas container, set of solvent containers, oven, and a collection vial for the samples. The solvent is moved through the heated extraction cell. When the extraction is complete, compressed gas (e.g., nitrogen) moves the solvent to the collection vial for analysis. High-pressure/-temperature automated samplers are used to obtain samples of pharmaceuticals, including herbal products and pollutants (e.g., pesticides, explosives) from environmental samples.
