It relies on pumps to pass a pressurized liquid solvent containing the sample mixture through a column filled with a solid adsorbent material.G2-M DNA damage checkpoint: The G2-M DNA damage checkpoint is an important cell cycle checkpoint in eukaryotic organisms ranging from yeast to mammals. This checkpoint ensures that cells don't initiate mitosis before they have a chance to repair damaged DNA after replication.Dioxetane: A dioxetane or dioxacyclobutane is an organic compound with formula C2O2H4, whose backbone is a four-membered ring of two oxygen atoms and two carbon atoms. There are two isomers:Perchloromethyl mercaptanConcentration effect: In the study of inhaled anesthetics, the concentration effect is the increase in the rate that the Fa(alveolar concentration)/Fi(inspired concentration) ratio rises as the alveolar concentration of that gas is increased. In simple terms, the higher the concentration of gas administered, the faster the alveolar concentration of that gas approaches the inspired concentration.FerroceneSodium ferric gluconate complexIron chelate: Iron chelate, also known as chelated iron, is a soluble complex of iron, sodium and a chelating agent such as ethylenediaminetetraacetate (EDTA), EDDHA, or others, used to make the iron soluble in water and, for the purposes of agriculture, accessible to plants.Thiourea dioxidePhenolic acid: Phenolic acids or phenolcarboxylic acids are types of aromatic acid compound.
