  2. Dialysis tubing - Wikipedia

    en.wikipedia.org/wiki/Dialysis_tubing

    Dialysis tubing, also known as Visking tubing, is an artificial semi-permeable membrane tubing [1] used in separation techniques, that facilitates the flow of tiny molecules in solution based on differential diffusion.

  3. Viskase - Wikipedia

    en.wikipedia.org/wiki/Viskase

    Viskase (formerly Visking) is a global corporation based out of Lombard, Illinois, United States that supplies plastic, cellulose, and fibrous film and packaging to the food service industry, including casings for processed meats such as hot dogs and sausages.

  4. Dialysis (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Dialysis_(chemistry)

    Dialysis is the process used to change the matrix of molecules in a sample by differentiating molecules by the classification of size. [6] [7] It relies on diffusion, which is the random, thermal movement of molecules in solution (Brownian motion) that leads to the net movement of molecules from an area of higher concentration to a lower concentration until equilibrium is reached.

  5. Feeding tube - Wikipedia

    en.wikipedia.org/wiki/Feeding_tube

    A gastric feeding tube (G-tube or "button") is a tube inserted through a small incision in the abdomen into the stomach and is used for long-term enteral nutrition. One type is the percutaneous endoscopic gastrostomy (PEG) tube which is placed endoscopically. The position of the endoscope can be visualized on the outside of the person's abdomen ...

  6. Microwave digestion - Wikipedia

    en.wikipedia.org/wiki/Microwave_digestion

    Microwave digestion is a chemical technique used to decompose sample material into a solution suitable for quantitative elemental analysis. [1] It is commonly used to prepare samples for analysis using inductively coupled plasma mass spectrometry (ICP-MS) , atomic absorption spectroscopy , and atomic emission spectroscopy (including ICP-AES ).

  7. Digestive enzyme - Wikipedia

    en.wikipedia.org/wiki/Digestive_enzyme

    Digestive enzymes take part in the chemical process of digestion, which follows the mechanical process of digestion. Food consists of macromolecules of proteins, carbohydrates, and fats that need to be broken down chemically by digestive enzymes in the mouth , stomach , pancreas , and duodenum , before being able to be absorbed into the ...

  8. Kjeldahl method - Wikipedia

    en.wikipedia.org/wiki/Kjeldahl_method

    The Kjeldahl method or Kjeldahl digestion (Danish pronunciation: [ˈkʰelˌtɛˀl]) in analytical chemistry is a method for the quantitative determination of a sample's organic nitrogen plus ammonia/ammonium (NH 3 /NH 4 +). Without modification, other forms of inorganic nitrogen, for instance nitrate, are not included in this measurement.

  9. TNO intestinal model - Wikipedia

    en.wikipedia.org/wiki/TNO_intestinal_model

    TNO (gastro-) Intestinal Models (“TIM”) is a system of models mimicking the digestive tract. The system was developed by TNO, the Netherlands Organisation for Applied Scientific Research.
